PC is a pale yellow or colorless fully transparent raw material, hard and durable with high luster. It is resistant to weak acids, alkalis, and neutralized oil. It is not resistant to ultraviolet rays or strong acids.High-content PC epoxy resins offer excellent elongation properties. The thermal expansion temperature for unfilled types is approximately 130°C, which can be increased by 10°C with the addition of glass fiber. The bending strain rate of PC is around 2400MPa, allowing for the production of large-stiffness products. Below 100°C, the stress relaxation rate under load is very low. PC has poor hydrolytic resistance and is not suitable for products that repeatedly withstand high-pressure steam.The key characteristics and drawbacks of PC are insufficient reliability against hydrolysis reactions, sensitivity to notches, good resistance to analytical chemicals, weak resistance to scratches, and it turns yellow when exposed to UV light for a long time. Like other epoxy resins, PC is highly susceptible to being clouded by some solvents.Polycarbonate is colorless, fully transparent, impact-resistant, flame-retardant to BI grade, and often exhibits excellent physical properties within general application temperatures. Compared to polymethyl methacrylate with similar properties, polycarbonate offers better impact resistance, higher refractive index, good processing characteristics, and can achieve UL94 V-0 flame-retardant rating without the need for preservatives.
