LEXAN 920A PC SABIC Product Features:
Features: flame retardant, good surface gloss
Form: Pellets
Processing method: injection molding
PC has excellent performance, high transparency, good impact toughness, creep resistance, and wide temperature range. Process characteristics of PC: melt viscosity is less sensitive to shear rate, but more sensitive to temperature, no obvious melting point, high melt viscosity, easy hydrolysis of resin at high temperature, and easy cracking of products.
1. To increase the fluidity of the melt, it is not by increasing the injection pressure but by increasing the injection temperature;
2. The runner and gate of the mold are required to be short and thick to reduce the pressure loss of the fluid and at the same time require a higher injection pressure;
3. Sufficient drying is required before processing to keep the water content below 0.02%;
4. In addition, heat preservation measures should be taken for the resin during processing to prevent re-absorption of moisture;
5. Not only a reasonable product design is required, but also the molding process should be correctly mastered, such as increasing the mold temperature and post-processing the product to reduce or eliminate internal stress. Adjust the process parameters in time according to the different conditions of the product.
