PBT custom injection molding plastic parts
Description
PBT is a crystalline thermoplastic polyester with high heat resistance, toughness, fatigue resistance, self-lubrication, low friction coefficient, weather resistance, and low water absorption. PBT injection molding process characteristics and process parameter settings: PBT has a mature polymerization process, low cost, and easy molding and processing.
The characteristics of PBT injection molded parts are as follows:
- Mechanical properties: high strength, fatigue resistance, dimensional stability, and small creep (very few changes under high temperature conditions);
- Heat aging resistance: The enhanced UL temperature index reaches 120~140℃ (the long-term outdoor aging resistance is also very good);
- Solvent resistance: no stress cracking;
- Water stability: PBT is not easy to decompose when encountering water;
- Electrical performance: excellent insulation performance (it can maintain stable electrical performance under humidity and high temperature, and is an ideal material for manufacturing electronic and electrical parts); the dielectric coefficient is 3.0-3.2; the arc resistance is 120s;
- Molding processability: Injection molding or extrusion molding with ordinary equipment. Due to its fast crystallization speed and good fluidity, the mold temperature is also lower than other engineering plastics. When processing thin-walled parts, it only takes a few seconds, and it only takes 40-60s for large parts.
Application
PBT injection molded parts are widely used in automobiles, electronics/electrical appliances, machinery industry and other fields.
In the automotive field, PBT, as one of the engineering plastics, is widely used in automobiles due to its excellent mechanical properties, mechanical strength, fatigue resistance and dimensional stability.
In the field of electronics/electrical appliances, PBT is usually mixed with 30% glass fiber as a connector. PBT is widely used due to its mechanical properties, solvent resistance, good formability and low price.
