TPO: Thermoplastic Olefins
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. Aurora Material Solutions offers both halogenated and non-halogenated TPO based materials through its AuroraGuard™ product line.
AuroraGuard™ TPOs are used primarily as flame-retardant, polyethylene-based in the wire and cable market; flame-retardant, polypropylene for the battery market (UL 94 V0 & V2); and interior, exterior and paintable applications for the automotive market. Various fillers and additives are also incorporated to meet required specifications by material & design engineers. For example, all AuroraGuard™ TPOs can be color matched with UV additives to pass OEM accelerated weathering and two year outdoor weathering tests.
Recent TPO development 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.
