LCP Injection Molding

Liquid crystal polymer is a high-performance engineering thermoplastic that provides excellent heat resistance and mechanical properties.

Product Description

Liquid crystal polymer (LCP) materials have high temperature capability and flow easily. It is especially well-suited to applications that require very thin walls. Vectra E130i is a glass-filled LCP that is exceptionally flame retardant and has a high tensile strength and modulus, making it a solid choice for structural applications. Beyond that, it offers good chemical resistance to a variety of acids, bases, and solvents.
