Is polycarbonate PC resistant to low temperatures

PC material is a common plastic material that is widely used in many fields, such as electronic products, auto parts, building materials, etc. However, many people have some misunderstandings about whether PC materials are resistant to low temperatures.

First of all, the PC material itself has certain low temperature resistance. The glass transition temperature of PC is -40°C, indicating that the material can be used at lower temperatures without becoming brittle. In addition, PC has good impact resistance and can withstand temperature changes and external impacts to a certain extent.

However, the low-temperature resistance of PC materials is not unlimited. If PC material is exposed to extremely low temperatures, its performance may be affected. For example, at extremely low temperatures, PC materials may become brittle and their impact resistance may decrease. Therefore, PC materials may not be the best choice in extreme low-temperature environments.

In addition, the low-temperature resistance of PC materials is also affected by its formula, additives, plasticizers and other factors. Some formulations and additives of PC materials can improve their low-temperature resistance, but these improvements may be limited because the essence of PC materials is thermoplastics and their low-temperature resistance is relatively poor.

However, among the current SABIC Lexan™ series products, EXL1414, EXL1192T, EXL1132, and EXL1330 are low-temperature-resistant silicon copolymer PCs with chemical resistance, which can meet customers' requirements for low-temperature resistance of PCs. Silicone PC (Silicone Polycarbonate) refers to the composite material of polycarbonate (PC) plastic and silicone rubber (Silicone Rubber). This composite material combines the benefits of polycarbonate plastic and silicone rubber to enable a wider range of applications and improved performance.

Polycarbonate (PC) is an excellent engineering plastic with high strength, high heat resistance, good transparency and chemical resistance. It is often used to manufacture parts with transparent or high strength requirements, such as transparent covers, automobiles, etc. Lampshades, glasses lenses, etc.

Silicone rubber is an elastic material with good high temperature resistance, low temperature resistance, ozone resistance, electrical insulation and other properties. It is widely used in seals, sound insulation, electronic components and other fields.

Silicone PC materials are obtained by compounding polycarbonate and silicone rubber, which can combine the high strength and heat resistance of polycarbonate with the elasticity and temperature resistance of silicone rubber. Silicon PC materials are often used to manufacture products that require high temperature resistance, low temperature resistance, and good elasticity, such as automotive seals, electronic components, medical equipment, etc.
