Advantages and application of cycloolefin polymer COP, a new injection molding material

Injection molding material cycloolefin polymer COP has excellent properties. Under the background of rapid growth in the field of optical components related to flat panel LCD TV and mobile phone terminal, COP is widely used in optical components such as light guide plate, optical pickup lens and optical disc for flat panel display. Cycloolefin polymer COP has the advantages of less impurities, minimal water absorption, good fluidity and excellent transparency.

1. Less impurities

Due to its low content of chemicals and other impurities, it can be used in tableware, sanitary products, chemical containers, and semiconduction-related equipment. When designing injection moulds for cycloolefin polymers, it is necessary to consider maximizing these resin properties.

2. Minimal water absorption

The water absorption rate is less than 0.01%, which reaches the highest level among thermoplastic resins and has good dimensional stability after injection molding.

3. Good liquidity

PMMA and PC, as transparent resins, have poor fluidity and difficulty in molding during injection molding. However, the melt flow rate of cycloolefin polymer is better, which can reach about 4 times of PC and about 1.5 times of PMMA. Therefore, injection molding can be carried out at a lower filling pressure.

4. Excellent transparency

Compared with acrylic resin and polycarbonate resin, it has excellent total transmittance and excellent transparency. Therefore, it can be said that this material has the best properties as a lens and light guide plate function.

Cycloolefin polymer COP has excellent transparency, heat resistance and good surface transfer of injection mold, so it is increasingly used in lens injection molding products. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before mold production with customers from the production needs of finished products, so that the mold delivery time is short, the life is long, the mass production is fast and the finished product quality is excellent!
