Thermoplastic Polyolefins (TPO or TPE-O)
TPO compounds are resin blends of polypropylene (PP) and un-crosslinked EPDM rubber and polyethylene. They are characterised by high impact resistance, low density and good chemical resistance.
They are used in applications where there is a requirement for increased toughness and durability over the conventional PP copolymers, such as automotive bumpers and dashboards. The properties are restricted to the high end of the hardness scale, typically >80 Shore A and with limited elastomeric properties.
TPOs can be easily processed by injection moulding, extrusion or blow moulding.
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 Specialty Polymers offers both halogenated and non-halogenated TPO based materials.
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 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 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.
specialty fire retardant thermoplastic polyolefin (TPO) based compounds are designed for insulating and filler wire & cable applications. As polyolefin manufacturers we understand that flame retardant and good electrical properties are essential.
