Soft components, 2k-moulding and overmoulding

DzBh® New Material SBS and SEBS styrene copolymers are used – alone or combined in TPO compounds with EVA, PE or PP - for 2k-moulding and overmoulding of very soft components with rubber appearance and properties. SBS and SEBS have good adhesion on PP.


Arkema Evatane® EVA or Lotryl® EMA, EBA ethylene copolymers are soft and flexible polyolefins which are used in the 1k-injection moulding of very flexible components. Evatane® is also a perfect choice for the replacement of flexible PVC. Applications may include soft small seals, liners, covers without any specific requirement in terms of wear, heat or chemical resistance.

Arkema Pebax® and Sipol Sipolprene® are Thermoplastic Elastomers based respectively on polyamide and polyester copolymers. They are a great alternative to standard SBS, SEBS, TPO, TPU or TPV when superior versatility, flexibility, softness, tenacity, resilience, durable elastic return, heat, chemical and abrasion resistance, and great esthetic and touch properties are required. They are widely used in high value 1k-, 2k-injection moulding and overmoulding. Applications include hoses and fittings for air and fluids, tubes for cable lines, gear knobs, sealings for battery housing.


Ambra also developed a 100% ecorecycled TPC-ET alternative - named TPC Regrind Black 1 - read about at the paragraph on Recycling and Sustainability.


Strong adhesion is crucial in 2k- or overmoulding of soft components to stiffer substrates. Both Pebax® and Sipolprene® show excellent adhesion on most polyolefins and engineering polymers, except PP, POM and few others.

Arkema Lotader® and Orevac® reactive polyolefins will promote adhesion of PE, PP, PS, PA, PET, PBT, TPE on various substrates. Orevac® and Lotader® will also promote compatibilization between two components in blend mixtures before extrusion.
