Sabic valox PBT plastic is a kind of plastic composed of polybutylene terephthalate. It is a semi crystalline material with very good chemical stability, mechanical strength, electrical insulation characteristics and thermal stability.
PBT applications
Electronic and electrical: connectors, plugs, sockets, coil frames, fuse boxes, non fusible wire breakers, flyback transformers, household appliance handles, housings, etc., terminal blocks, various transformer spools, microswitches, meters, various timers and watch bases, and various switches.
Automobile: door handle, bumper, distributor cover, fender, wire housing, rim cover, starter igniter, distributor, carburetor and gearbox.
Industrial parts: OA fan, keyboard, fishing tackle reel, parts, lampshade, lamp cap, etc.
Sabic valox DR51 is a 15% glass reinforced, excellent mechanical, thermal and electrical performance. Non-flame retardant. .Numerous applications: edge trimmers, food mixer motor stator and commutator, cooling fan, connectors, bobbins, switches,spotlights, appliance housings, handles,etc
