Structure:

pbt-re1.jpg (3745 bytes)

Property:

- Good heat resistance (especially in melting point and distortiontemperature) so as to can be used at high temperature continuouslyand have long time heat stability;
- High mechanical strength、low friction coefficient and abrasion proof;
- Low moisture absorption so as to has less effect on mechanism and stability after saturation;
- PBT engineering plastics show inertia to the majority of chemicalmedicine except for hot water and alkali;
- Good fluidity and easy machine-shaping, short cycle time and excellent surface lubricity and lustre so as to can be made to wallthinness and complicated shape product;
- Include Ultra-resistance grade and can be used to special appliances;
- Flame retardance meeting the requirements of UL 94 standards (E139063).


Typical Application: - Illuminate electric Power adapter stock and base of energy-saving light and lamps housing.

Use Method: - Need to dry before injection molding, you can dry it at 120-130 ℃ for 4-5 hours (material thickness
not exceeding 3 cm).
