PC / PBT Black compounds

A polycarbonate (PC) and poly (butylene terephthalate) (PBT) blend is extensively used for moulded automobile parts. PC is tough and stable to 300 °C and PBT has relatively good solvent resistance. An alloy formed with those two polymers produces a material with good chemical resistance as well as good heat and impact resistance.Tensile and impact properties and melt flow index were evaluated before and after aging, and also after recycling. The rupture elongation of the recycled material was very good, showing the recycling potential of this material.

Properties

By varying proportion of these monomers properties like impact strength can be adjusted to suit applications. It is an amorphous thermoplastic and having high rigidity, high heat deflection temperature, scratch resistance, impact resistance & low shrinkage.

Application

• Windshield wiper covers
• Mirror housings
• Cowl vents
• Handles and fans
• Fuel system components
• Connectors, sensor housings and fuse boxes
• Motor components and ignition system component
