Composite materials

Biosourced resins and liquid resins for thermoplastic composites, latest generation structural adhesives, specialty additives… The Arkema Group offers innovative and custom-made solutions for ever more efficient composites for aerospace, automotive, sailing, sports equipment, and wind power.

Our materials for outstanding composite matrices

Manufacturers are showing a growing interest in biomaterials, lightweight materials, and the recycling of their products. To address these concerns, Arkema has developed suitable resins and polymers that improve the performance of their composites.

Elium®

Thermoplastic resins Elium®, liquid at ambient temperature, unique on the market, to manufacture thermoformable and recyclable thermoplastic composite parts.

They are suitable for traditional processing technologies such as RTM, infusion and FlexMolding™, and therefore allow to produce thermoplastic composites with same equipments than for thermosets.

Polystrand®

Polystrand® materials combine high strength fibers and engineered thermoplastic resins to make Continuous Fiber Reinforced Thermoplastics (CFRTP). Polystrand® CFRTP materials are available in multilayer rolls of tape or prepregs (X-ply®) that can be processed by thermo-compression or thermo-stamping.
The use of Polystrand® offers opportunities to reduce weight while maintaining exceptional strength and impact resistance.

Kepstan®

Kepstan® PEKK often used to replace metal in extreme conditions (offshore, aviation). Thanks to this high performance polyether ketone ketone, the final composite is endowed with superior resistance to violent impact, high temperatures, and highly aggressive chemical agents.

Kynar® UHM™ PVDF

The Kynar® UHM™ PVDF thermoplastic resin is used for overmoulding or bonding to composite parts. It offers superior mechanical properties, including greater rigidity as well as excellent high temperature and fire resistance. Easy to process, Kynar® PVDF resins feature outstanding UV and chemical resistance. The most demanding industrial applications will find in Kynar® UHM™ a material that is strong, reliable, durable and highly cost-effective compared to other solutions.

Rilsan®

100% biosourced, this high performance polyamide, in the form of fine powder or granules, imparts chemical stability, abrasion resistance and impact resistance to composites even at very low temperatures. The Rilsan® polyamide matrix is used to produce thermoformable and recyclable thermoplastic composites.

The Mini 6.50 Arkema 3 prototype, an expression of innovation

Additives for tougher composites

Our innovative additives significantly improve the inherent properties of composite materials.

éolienne

Graphistrength®

Graphistrength® carbon nanotubes significantly improve the mechanical strength of composites. They also prevent the build-up of electric charges in the resulting components. Hence they fulfil the requirements of aerospace and automotive manufacture.

Dianol®

The Dianol® product range, diol-based polyether polyols from CECA, improve the thermal and chemical stability of polyester resins.

Nanostrength®

Nanostructured acrylic block copolymers Nanostrength® act as additives at the very heart of the material. They help enhance the impact resistance of the matrix with no loss of module or temperature stability. They can be used both in epoxy or vinyl ester composite matrices and in structural adhesives.

Sartomer®

Sartomer®, an Arkema subsidiary and a major player in high performance resins for the composites market, provides solutions for replacing styrene (less toxic).
The use of acrylate and methacrylate specialty resins (monomers, MCURE®, epoxy, etc.) significantly improves the performance of composite matrices.

Orgasol® polyamide powders

Orgasol® polyamide powders, a thermoplastic ultra-fine powders, minimise crack propagation at the fibre-matrix interface in thermoset prepregs. As a result, the final composites are tougher and longer lasting.

Luperox®

Luperox® organic peroxides and BlocBuilder® RC50 reactivity controller. Luperox® organic peroxides are crosslinking agents for unsaturated polyester resins (including foam) that help speed up processing and ensure better control of continuous or semi-continuous processes to produce harder composite resins.
BlocBuilder® RC50 reactivity controllers ensure the efficient performance of organic peroxides by controlling gelling and heat curing more effectively.

Structural adhesives for easy-to-process high-performance assemblies

Structural adhesives play a major role in the assembly of composite parts between them or with other materials (metal, plastics, aluminium, glass, etc.).

AEC Polymers

  • BlackMamba® sealants - adhesive sealants: their permanent elasticity allows complex assemblies with no loss of mechanical strength. They can withstand UVs and moisture within a wide temperature range.
  • SAF® two-component structural adhesives: these methacrylate adhesives combine strong adhesion without the need for a primer on many substrates, very good flexibility thanks to the Nanostrength® block copolymer technology, and adjustable curing times (5 minutes to 2 hours).

Platamid®

Platamid® hot melt adhesives is plasticiser-free and solvent-free. These thermoplastic copolyamides ensure excellent adhesion, with little product required, on a wide range of substrates: composite materials, textile, metal, leather, plastics. Arkema offers an extensive range of Platamid® adhesives, some of which are biosourced grades, available in the form of powder or granules (for processing into film, web or filament). Additionally, they help improve productivity through shorter cycle times, and can be reused and recycled.
