Engineering thermoplastics compounding underpins global automotive, electronics, and industrial manufacturing.
Overview
On April 30, 2026, U.S.-based private equity firm Lone Star Funds announced the completion of one of the most significant consolidation moves in the engineering plastics industry in years: the simultaneous acquisition of RadiciGroup’s High Performance Polymers and Specialty Chemicals businesses, and the signing of binding agreements to acquire DOMO Engineered Materials — the company behind the globally recognized TECHNYL® polyamide brand. The two transactions, executed in parallel, create a new standalone global platform for polyamide compounding that will carry the RadiciGroup, DOMO, and TECHNYL® brands under unified ownership. The combined entity is positioned as an independent tier-1 compounder serving the automotive, electrical and electronics, industrial, construction, and consumer markets worldwide.
The Dual Acquisition: What Was Announced and When
Lone Star announced on April 30, 2026 that an affiliate of Lone Star Fund XII, L.P. has completed the acquisition of RadiciGroup, with its High Performance Polymers and Specialty Chemicals business areas, and has signed binding transaction agreements for the acquisition of DOMO Engineered Materials, with closing expected to occur imminently.
The simultaneous and highly complex acquisition of these businesses will bring together two established platforms to form a global, independent tier-1 compounder, with a broad and complementary product portfolio, expanded geographic reach, and enhanced capabilities to serve a diversified range of end markets.
Jochen Fabritius has been appointed CEO of the combined organization. He brings over 25 years of industry and consulting experience and has been leading companies in the Lone Star portfolio for the last 10 years.
Donald Quintin, CEO of Lone Star, described the transaction as a deal that "creates a scaled platform with significant industrial and technological capabilities" that "will not only strengthen the competitive positioning of the business globally, but also provide the resources and stability needed to drive innovation, support customers and protect industrial know-how and employment."
Who Are RadiciGroup and DOMO Engineered Materials?
RadiciGroup is an Italian family-owned industrial group founded in 1941 and headquartered in Bergamo, Italy. With 3,000 employees, sales of €1,069 million in 2023, and a network of production units and sales offices across Europe, North and South America, and Asia, RadiciGroup is a global leader in the production of a wide range of chemical intermediates, polyamide polymers, high-performance engineering polymers, and advanced textile solutions.
The Chemicals Area generates roughly €300 million in revenue, while the Polymers Area contributes about €500 million. The Novara site alone spans over 350,000 square meters and specializes in polyamide 66 production, a critical material for high-performance applications. RadiciGroup’s engineering polymer portfolio covers glass and mineral fiber reinforced nylons, flame-retardant grades, and recycled and bio-based polyamide solutions for demanding end markets.
DOMO Engineered Materials is the engineering materials division of Belgium-based DOMO Group. With nearly 70 years of experience, the TECHNYL® brand supports a wide range of high-performance applications in the automotive, electrical and electronics, building and construction, consumer goods, and industrial sectors. TECHNYL® is one of the most established PA66-based engineering plastics brands in the world, with deep penetration in European and global automotive supply chains.
DOMO Engineered Materials offers a comprehensive portfolio including STAR and MAX for lightweighting and metal replacement; ONE, RED, and PROTECT for heat and flame resistance; SAFE for water and food contact applications; PURE for electrical applications; and SHAPE for extrusion. The TECHNYL® 4EARTH range includes recycled and bio-based materials.
What the Combined Platform Looks Like
The merger creates a polyamide compounding group with full vertical integration — from chemical intermediates through polymer production to finished engineering compounds — across Europe, the Americas, and Asia. Following completion, the combined platform will leverage well-established brands, including RadiciGroup, DOMO, and TECHNYL®, while continuing to serve customers with a reinforced commitment to quality, reliability, and technical innovation.
The future combined business will have a broad and complementary product portfolio, expanded geographic reach, and enhanced capabilities to serve markets including automotive, construction, consumer, and industrial applications.
The vertical depth of the combined entity is rare in the engineering plastics industry. Most compounders buy base polyamide resin from chemical producers and compound it into finished grades. The RadiciGroup + DOMO combination controls both the upstream chemistry — adipic acid and hexamethylenediamine intermediates for PA66, and caprolactam-based chains for PA6 — and the downstream compounding and formulation stages. This structure gives the combined group significant cost insulation during resin price volatility and the ability to develop proprietary polymer architectures not accessible to toll compounders.
The Polytechnyl Thread: TECHNYL® Brand Secured, French Production Shutting Down
A parallel development gives additional context to the DOMO transaction. Polytechnyl entered judicial restructuring proceedings, known in France as redressement judiciaire, earlier this year. The Lyon Commercial Court approved Lone Star’s acquisition of key Polytechnyl assets. Polytechnyl had been a key player in engineering polymers, particularly after acquiring the TECHNYL brand from Solvay in 2020.
However, the asset rescue comes with a significant industrial cost. Lone Star is acquiring Polytechnyl’s brand and R&D operations but shutting down nylon production at the French manufacturing site. This means the TECHNYL® brand, its R&D pipeline, and its formulation know-how transfer to the new combined group — but production from that specific site will end.
The three-way convergence of RadiciGroup, DOMO Engineered Materials, and Polytechnyl’s brand assets under a single owner is not accidental. It reflects a deliberate strategy to assemble a polyamide compounding platform with the broadest possible portfolio of PA grades, application expertise, and brand equity, regardless of which production sites are retained.
Why Polyamide Compounding Is Attracting Major Capital Right Now
Polyamides — PA6 and PA66 in particular — are among the most strategically important engineering thermoplastics in global manufacturing. They sit at the intersection of several high-growth demand vectors in 2026:
Automotive lightweighting and electrification. As vehicle platforms shift from combustion to electric powertrains, the materials mix inside a vehicle changes substantially. High-voltage connectors, battery housings, thermal management components, and structural brackets that previously used metal are increasingly specified in glass-filled or flame-retardant polyamide. The TECHNYL® PROTECT and ONE grades are directly positioned for this transition.
Electrical and electronics miniaturization. Consumer electronics, industrial automation, and power infrastructure components are pushing connector and housing materials to higher thermal class ratings — above 130°C continuous use — where standard polyamide formulations are being replaced by upgraded heat-stabilized or high-flow PA grades.
Sustainability mandates. European automotive OEMs are requiring increasing recycled content in purchased polymer components. Both RadiciGroup and DOMO have invested in recycled-content polyamide grades — TECHNYL® 4EARTH and RadiciGroup’s bio-based solutions — that allow downstream processors to meet end-of-life vehicle and circular economy requirements.
Supply chain consolidation preference. Tier-1 automotive suppliers increasingly prefer to qualify fewer, larger material suppliers who can guarantee global supply consistency across multiple manufacturing regions. A combined RadiciGroup + DOMO entity is better positioned to offer that guarantee than either company operating independently.
What This Consolidation Means for Downstream Processors
For injection molders, extruders, and compounders that process polyamide-based engineering plastics, the Lone Star consolidation carries several practical implications:
Broader portfolio under one qualification. If your facility is currently qualified on both TECHNYL® and RadiciGroup grades for similar applications, the combined supplier relationship simplifies commercial negotiations — but also reduces the number of independent supplier relationships available for dual-sourcing strategies.
R&D investment likely to accelerate. Lone Star’s stated rationale explicitly includes accelerating innovation. A combined R&D budget, combined formulation database, and combined application engineering team should shorten the development cycle for new high-performance grades — particularly in EV, battery, and high-temperature electrical applications.
Pricing dynamics may shift. Consolidation in a specialty materials segment typically reduces short-term competitive pressure between the merged parties. Downstream processors should review long-term supply agreements for volume commitments and price escalation clauses while the combined entity establishes its commercial structure.
Qualification windows may open. Post-acquisition portfolio rationalization often creates discontinuities — grades that are phased out, production shifted between sites, or specifications revised. Processors should proactively engage their account contacts at both RadiciGroup and DOMO to understand whether any currently approved grades are affected by the integration.
Processing Equipment for High-Performance Polyamide Compounds
Polyamide processing presents specific technical demands that determine compound quality and consistency. PA6 and PA66 are hygroscopic — they absorb atmospheric moisture rapidly and must be dried to precise moisture levels before extrusion or injection molding. Glass fiber reinforced grades require careful screw design and downstream handling to preserve fiber length. Flame-retardant grades require precise additive dispersion to achieve UL94 ratings.
For compounding facilities processing polyamide engineering plastics, the following equipment stages are critical:
- Pre-drying and VOC management: PA6 and PA66 must be dried to below 0.2% moisture before compounding to prevent hydrolytic degradation and void formation. Nicety Machinery’s VOC Deodorizing Drying System handles both moisture removal and volatile control, protecting compound quality especially for flame-retardant grades where decomposition residues can affect performance ratings.
- Additive and masterbatch pre-blending: Glass fiber, flame retardants, stabilizers, and impact modifiers must be pre-dispersed before entering the compounding extruder. The High Speed Mixer Machine provides the shear energy needed for uniform distribution of powdered and granular additives into the base polymer, reducing agglomeration and improving downstream dispersion.
- Pellet and powder conveying: Glass-filled polyamide compounds are abrasive. Conveying systems must handle this without excessive wear or segregation between pellets and fines. The Screw Conveyor and Vibrating Spiral Elevator provide reliable material movement between process stages.
- Strand pelletizing and surface drying: Most engineering polyamide compounds are processed through strand pelletizing lines with water bath cooling. The Strand Line Centrifugal Dryer removes surface moisture from the pellet strand immediately after the water bath, before classification and packaging — preventing pellet clumping and maintaining the low bulk moisture specification that downstream molders require.
- Post-pelletizing size classification: For glass-filled or specialty PA compounds, consistent pellet size is critical for uniform feeding in injection molding. The Linear Vibrating Screener removes fines and oversized pellets, ensuring every kilogram shipped meets the dimensional specification.
- Bulk blending for multi-grade facilities: Facilities processing multiple polyamide grades — PA6, PA66, PA6/66, recycled grades — need reliable bulk blending equipment for color mixing and grade transitions. The Horizontal Mixer and Vertical Silo Mixer handle these operations cleanly between production runs.
