Engineering Plastics

Engineering plastics are types of plastics that will have better chemical resistance, impact and mechanical strength then commodity plastics. They will perform better under extreme stress and heat.

What are engineering plastics?

Engineering plastics are thermoplastics that offer better properties than commodity plastics like PVC and styrene. Engineering plastics offer good mechanical properties, dimensional stability, chemical resistance and wear characteristics. Many engineering plastics are designed to have a unique combination of properties catering to specific applications. Some examples are highly impact-resistant polycarbonate, extremely heat resistant PEEK, and slippery self-lubricating PTFE.

What is the difference between engineering plastic and specialty plastic?

Engineering plastics are thermoplastics that offer better mechanical properties, dimensional stability, chemical resistance and wear characteristics than commodity plastics. Specialty plastics are plastics that meet higher specifications than commodity and engineering plastics. Most high-performance plastics specialize in maximum performance on a single property (i.e. heat or chemical resistance) and are used in very specific applications.
