In short, TPEs are a family of rubber like materials that combine the characteristics of rubber with the recyclability and processing advantages of plastics.

The science bit; like thermoplastics, when heated and with the application of shear force, TPEs become free-flowing and when cooled regain their original structure and stability. Unlike the chemical cross-linking which occurs in thermoset rubbers, TPE involves purely physical cross-linking, which can be reversed via the further application of heat, this makes it possible to re-use all production waste and end of life products can be easily reprocessed.

TPEs exhibit elasticity similar to that of a cross-linked rubber. Their softness or hardness value is measured on the Shore durometer scale. Our TPEs are available as ultra-soft gel like materials measuring 0 Shore A through to rigid materials measuring up to 65 Shore D, and just about every variation in-between.

It is this design flexibility, high-performance and ease of processing that has led to designers increasingly turning to TPEs as their material of choice. TPEs are used in a variety of applications in the automotive, medical, construction, electrical, appliance, packaging and industrial markets – and new uses for TPEs are being developed all the time.

Thermoplastic Polyolefins (TPO’s) are multiphase compositions in which one phase consists of a material that is hard at room temperature and fluid when heated, and the other phase consists of an elastomeric material that is soft and rubberlike at room temperature. JV Colors, Inc. Specialty Polymers offers both halogenated and non-halogenated TPO based materials.

We provide TPO’s for primarily the wire & cable, battery and automotive markets. Applications range from flame retardant polyethylene based materials for the wire & cable market, flame retardant polypropylene for the battery market (UL 94 V0 & V2) and interior, exterior & paintable applications for the automotive market. Various fillers and additives are also incorporated to meet required specifications by material & design engineers. For example, all our TPO’s can be color matched with UV additives to pass OEM accelerate weathering and two year outdoor weathering tests.

Recent TPO developmental efforts are concentrated on high melt flow compounds for thin wall and complex injection molding applications. We are able to achieve high melt flow rate while maintaining required physical properties, low weight, low CLTE, stiffness and impact balance.

We provide custom TPO development to address most customer requirements. Please contact sales and let us know how we can help.
