What materials are car interior door handles made of?

ABS resin was applied to car door handles early on. However, due to its poor mechanical properties, it is rarely used in door handles now.

PC is an engineering plastic with excellent mechanical properties, but its electroplating performance is not ideal, which limits its applications.

PC/ABS resin is the fastest-growing and most widely used material for interior car door handles. It is an alloy of PC and ABS, combining PC's high strength with ABS's good electroplating properties.

There are mainly two types: electroplating and spraying. Compared with spraying PC/ABS resin, electroplated PC/ABS resin has a more metallic feel and looks more high-end, which can meet consumers' requirements for the aesthetics of automotive interiors. Therefore, it is widely used in the mid-to-high-end car door handle market.

PC/PBT is a blend of PC and PBT, typically supplied in pellet form after compounding. It retains the chemical resistance and ease of molding characteristic of crystalline PBT, while also possessing the toughness and dimensional stability of amorphous PC.

PA has excellent mechanical properties, but its poor electroplating and water absorption are two major problems for its application in car door handles. In other countries, such as Germany, where high tensile strength is required, electroplated PA is widely used in German cars.

There are generally two types of PA used for car interior door handles: painted PA and electroplated PA. Electroplated PA is generally composed of PA + 20% mineral, with the addition of minerals to improve its performance to meet the requirements for door handle use.
