INQUIRY EMAIL

High-impact PC material--PC plastic has a very small shrinkage rate when it is molded, so its dimensional stability will be absolutely excellent. Polycarbonate materials have very high impact resistance In addition, it is also very heat-resistant and flame-retardant. Basically, it can be used in a relatively normal temperature range. It can maintain good mechanical properties, and the processing performance of polycarbonate materials is very good. Not only that, but its refractive index is also very high. It can be said that it has VO-level flame retardant performance without adding any additives at all.

The main advantage:

1. High strength and modulus of elasticity, high impact strength, wide temperature range

2. High transparency and free dyeability

3. Low molding shrinkage and good dimensional stability

Main applications: cups, cylinders, bottles, dental instruments, drug containers and surgical instruments that can be used for medical purposes, and can even be used as artificial organs such as artificial kidneys and artificial lungs; they can also be used for movie projector lenses, copier lenses, infrared Auto-focusing projector lenses, laser beam printer lenses, various prisms, polygonal mirrors, and many other office equipment and home appliances.
