PEI Injection Moulding
High-performance thermoplastics that offer high heat resistance, chemical resistance, and mechanical strength.
What is PEI Material?
PEI is a high-performance thermoplastic that offers high heat resistance, chemical resistance, and mechanical strength. A popular material for harsh environments, PEI is also referred to as its brand name, Ultem.
We offer the following type of PEI via our injection moulding service:
Ultem 1000: amorphous, transparent plastic. This inherently flame-retardant resin has UL94 V0, V2, and 5VA ratings and is RoHS compliant. ULTEM 1000 resin is an unreinforced general-purpose grade offering high heat resistance, high strength, and modulus and broad chemical resistance up to high temperatures.
