Characteristics of PBT modified plastic products:
1. Mechanical function: high strength, fatigue resistance, stable scale and small creep (rarely changed under high temperature conditions);
2. Heat aging resistance: the enhanced UL temperature index reaches 120~140 ℃ (outdoor long-term aging resistance is also very good);
3. Solvent resistance: no stress cracking;
4. Water stability: PBT is easy to differentiate in case of water (caution should be taken in application under high temperature and high humidity environment);
5. Electrical function:
A. insulation function: excellent (it can maintain stable electrical function even in humidity and high temperature, which is the ideal data for making electronic and electrical parts);
B. dielectric coefficient: 3.0-3.2;
C. arc resistance: it only takes a few seconds to process thin-walled parts, and only 40-60s for large parts.
D. molding processability: injection molding or extrusion of general equipment. Due to the fast crystallization speed and good fluidity, the mold temperature is also lower than that of other engineering plastics.
