Характеристики
Specification
Modle number | KY-TR4001 |
Material | Polybutylene Terephthalte PBT |
Form | Plastic Pellets |
Characteristic
a, mechanical properties: high strength, fatigue resistance, dimensional stability, creep is also small (very little change under high temperature conditions);
b, heat aging resistance: enhanced UL temperature index of 120 ~ 140 ℃ (outdoor long-term aging is also very good);
c, solvent resistance: no stress cracking;
d, water stability: PBT is not easy to decompose in the presence of water;
e. Electrical performance:
1, insulation performance: excellent (moisture, high temperature can also maintain the electrical properties of stable, is the ideal material for the manufacture of electronic and electrical parts);
2、Dielectric coefficient: 3.0-3.2;
3、Arc resistance: 120s
f, molding processability: common equipment injection or extrusion. Due to the fast crystallization speed and good fluidity, the mold temperature is also lower than that required by other engineering plastics. When processing thin-walled parts, it only takes a few seconds, and for large parts, it only takes 40-60s.
Application of PBT (usually refers to modified varieties);
a, electronic appliances: connectors, switch parts, household appliances, accessories parts, small electric cover or (heat resistance, flame retardancy, electrical insulation, molding processability);
b, automotive :
1, external parts: mainly corner Grassan, engine heat release hole cover, etc.;
2, the internal parts: mainly the inner mirror brace, wiper bracket and control system valve;
3, automotive electrical parts: automotive ignition coil strand tube and various electrical connectors, etc.
c, machinery and equipment: video tape recorder belt drive shaft, electronic computer cover, mercury lamp cover, iron cover, baking machine parts and a large number of gears, cams, buttons, electronic watch housing, camera parts (heat-resistant, flame retardant requirements).
Process characteristics
PBT must be dried at 110~120℃ for about 3 hours before injection, the molding processing temperature is 250~270℃, and the mold temperature is controlled at 50~75℃ as appropriate. Because the material from the molten state once cooled, it will immediately solidify and crystallize, so its cooling time is short; if the nozzle temperature is not properly controlled (low), the runner (water mouth) is easy to cool and solidify, and the phenomenon of plugging will occur. If the barrel temperature exceeds 275℃ or the molten material stays in the barrel for more than 30 minutes, it is easy to cause the material to decompose and become brittle. When shutting down, PE or PP material should be used to clean the material tube in time to avoid carbonization.
