Application fields of modified PBT plastics

PBT is one of the five major engineering plastics, comprehensive performance, through the reinforcement, flame retardant, low warpage, high GWFI/GWIT, high CTI, high flow and other aspects of the modified PBT plastic is widely used in various fields.

Application of PBT Plastics in Electrical and Electronic Field

Capacitor shell, high-end induction cooker coil, rice cooker socket connector, micro switch, timer, coil skeleton, etc.

Application of PBT Plastics in Automotive Field

The applications of PBT in the automotive industry are also diverse, including electrical components such as ignition distributors, fuse boxes and connectors, as well as headlamp housings, headlamp baffles, window supports, door handles, wiper motor housings, central lock components, air filters and sensors, fuel pump and supply components and airbag components, window motor housings, locomotive motor parts, automotive transmission gear boxes, etc.

PBT plastic for connector

The connector is a bridge between signals and an indispensable component for transmitting electronic signals and power connections. The balanced physical properties and price of PBT are in line with the needs of the connector. PBT usually add 30% glass fiber blend as a connector, PBT because of mechanical properties, solvent resistance, good forming processability and low price is widely used.

PBT plastic for cooling fan

The second largest use of PBT is to use it in a cooling fan. The cooling fan is placed in a machine to rotate for a long time to help dissipate heat. It requires heat resistance, flame retardant, insulation and mechanical strength for plastic physical properties. PBT is usually applied as the outer frame of the cooling fan and the coil shaft of the fan blade in the form of 30% fiber addition.

PBT plastic for coil shaft

The third purpose of PBT is to serve as a coil shaft in transformers and relays. Generally, 30% of PBT fiber is injected into the coil shaft. The physical properties required for the coil shaft include insulation, heat resistance, solder resistance, fluidity, strength, etc. The applicable materials are phenolic resin, PBT, PA6 and PET. Phenolic resin has good properties, but its formability is not as good as PBT, so PBT resin is used for products with small size and complex shape. Although PBT welding has poor heat resistance, Europe, America, Japan and other countries with high environmental awareness have a tendency to increase the use of recyclable PBT.
