Plastic product now is widely used in our life. For some plastic products that need to be exposed to chemicals, it is necessary to ensure that the product has sufficient chemical resistance. Here are four chemical-resistant plastics that you can take them as a reference.
PTFE
PTFT, also known as Teflon, is a high molecular polymer with a low coefficient of friction. PTFE has excellent chemical resistance and is a suitable choice as a raw material for products that contact with chemicals. PTFE has high temperature resistance and can still be used stably at 260 degrees Celsius. It should be noted that PTFE itself is corrosive, and the mold and molding machine need to be coated with ant-corrosive layer.
PEEK
PEEK is a plastic material with super chemical resistant property, its temperature resistance can reach 170 degrees Celsius. Now it is an excellent choice for the aerospace and medical industries.
PVC
PVC material has good chemical stability, now is commonly used in piping systems, and it also can be used for chemical containers.
HDPE
HDPE is a thermoplastic material with good chemical resistance and corrosion resistance. HDPE has the properties of low moisture absorption and also has a good resistance to chemicals.
HDPE is resistant to chemical such as acid and alcohol, and its easy processing ability make it useful for piping system and outdoor equipment.
