The materials

Choose your performance

Typical values: see the technical data sheets for full data.

01 · Light, tough and cold-proof

Grades: unfilled, flexible, transparent, filled and recycled

PA12

Low density, low water uptake: About 1.01 g/cm³ and roughly 1.5% water absorption at saturation: stable stiffness and dimensions, wet or dry.
Impact strength in the cold: Stays tough well below zero: the reference material for winter sports and outdoor gear.
Chemical and fatigue resistance: Withstands sweat, oils and cleaning agents, and repeated flexing over the product's life.

Typical sport applicationsSki-boot shells and cuffs · Sole plates and cleats · Eyewear frames and lenses · Buckles and lacing systems · Hydration and brake tubing

02 · Stiffness at minimum weight

Typically 10–40% carbon fibre on PA12, PA6 or PA66

Carbon fibre filled polymers

Highest stiffness-to-weight ratio: Replaces aluminium and other metals in structural parts, taking weight out of the product.
Precision under load: Low creep and warpage for mechanisms and parts with tight tolerances.
Technical look, dissipative: A premium matt finish, and carbon fibre makes parts electrically dissipative.

Typical sport applicationsBike components · Ski bindings and boot spines · Racket and paddle handles · Running and football sole plates · Helmet inserts

03 · Rigid, stable, cost-effective

Typically 10–50% glass fibre on PA12, PA6 or PA66

Glass fibre filled polymers

Rigidity and heat resistance: Much higher modulus and heat deflection than the unfilled polymer, for load-bearing parts.
Dimensional stability: Low shrinkage and creep keep assemblies and hinges precise over time.
Best cost-performance: The most economical route to structural strength in high-volume moulded parts.

Typical sport applicationsIn-line and ice-skate frames · Buckles and binding parts · Fitness equipment · Racks, mounts and housings · Pole and grip inserts

04 · Maximum energy return

Hardness typically Shore 25D–70D · recycled grades available

PEBA

One of the lightest elastomers: Low density means lighter shoes and equipment, and less fatigue for the athlete.
High rebound: Returns energy at every stride: the reference material for racing midsole foams.
Flexible in the cold: Stays flexible and impact-resistant at low temperatures, with excellent flex-fatigue life.

Typical sport applicationsRunning midsoles (foam) · Football and athletics sole plates · Ski-boot cuffs · Ski and board top sheets · Light, flexible parts

05 · Abrasion resistance with grip

Hardness typically Shore 60A–75D · recycled ISCC PLUS grades

TPU

Outstanding wear resistance: Excellent abrasion and tear resistance for parts in contact with the ground and with each other.
From soft to rigid: A wide hardness range, from flexible straps to stiff shells, in one material family.
Bonds and overmoulds well: Good adhesion to textiles and other polymers: ideal for films, coatings and two-shot parts.

Typical sport applicationsOutsoles and heel counters · Ski-boot shells · Straps and watch bands · Protective guards · Films and coated textiles

06 · Soft touch and secure grip

From very soft to semi-rigid grades

TPE

Comfort at every contact point: Soft, warm-to-the-touch surfaces with a non-slip grip, even when wet.
Made for overmoulding: Dedicated grades adhere to rigid substrates such as PP and PA in two-shot moulding.
Easy to process and colour: Rubber-like feel with thermoplastic processing: fast cycles, any colour, recyclable scrap.

Typical sport applicationsHandles and grips · Goggle and mask seals · Fitness and yoga mats · Bottle valves · Straps, bumpers and pads

Sustainability

Lower footprint, same performance

Circular and bio-based materials that keep the performance of the original.

ISCC PLUS certified

Mass-balance certification for circular and bio-attributed materials, traceable along the chain.

Recycled grades

Recycled TPU, PEBA and PA12 for footwear and equipment, with the performance of the original material.

Bio-based PA11

A long-chain polyamide from renewable castor oil, a natural alternative to PA12 in many parts.

How we work
