With its unique mechanical, chemical and thermal properties, PEEK has many advantages over other polymers and is able to replace industrial materials such as aluminium and steel. It allows its users to reduce total weight, processing cycles and increase durability. Compared to metals, PEEK polymer allows a greater freedom of design and improved performance.
Polyvinylidene fluoride (PVDF) is a homopolymer with medium viscosity. Similar to other high-performance polymers it offers stability in the form of thermal, chemical or ultraviolet conditions. That means it has resistance to heat up to 149°C, is almost universally resistant to chemicals and solvents and is unaffected by long-term exposure to ultraviolet radiation.
POM-C is a copolymer showing high strength and modulus that make it particularly resistant to impact and fatigue. Due to its lighter weight, it is often used as a replacement for metals.
ULTEM™ Resin 1000 is an amorphous, transparent polyehterimide (PEI) plastic. It has a glass transition temperature (Tg) of 217°C and is able to withstand long-term exposure to elevated temperatures. This inherently flame retardant resin has UL 94 V0, V2 and 5VA ratings and is RoHS compliant. ULTEM™ Resin 1000 is an unreinforced general-purpose grade offering high strength and modulus as well as broad chemical resistance up to high temperatures. It, therefore, shows similar properties as PEEK, but is relatively cheaper and has a lower impact strength and usage temperature.
