Product Description

S-Plastics 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.

1. Mechanical properties: high strength, fatigue resistance, stable size and small creep (little change 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. Excellent long-term thermal deterioration.

4. Low water absorption, good mechanical properties and dimensional stability.

5. Good weather resistance.

6. Good abrasion resistance and abrasion resistance.

7. Good fluidity and crystallinity, suitable for rapid prototyping.

8. The improvement effect of glass fiber physical property is good.

9. Easy to reach V-0 level, physical properties can maintain electrical performance:

Insulation performance: excellent (wet and high temperature can also maintain stable electrical performance, and it is an ideal material for manufacturing electronic and electrical parts);

Dielectric coefficient: 3.0-3.2;

Arc resistance: 120s;

 

S-Plastics valox 357U is an unreinforced, UV stabilized, impact modified flame retardant Polybutylene Terephthalate/Polycarbonate (PBT) injection moldable grade. It has excellent chemical resistance and a UL94V0@0.64mm and 5VA@3.0mm flame rating. This is a good candidate for applications in the electrical industry including bobbins, switches, and enclosures.version of valox 357  is Nonblooming flame retardant.
