LCP, Liquid Crystal Polymers, are a family of high performance resins that have a unique structure with long, rigid, rod-like highly oriented molecules. LCP properties are influenced by its liquid crystal structure. Rod-like molecules are oriented in the flow direction during injection or extrusion moulding.
This unique molecular structure results in several exceptional LCP (Liquid Crystal Polymer) properties:
- Exceptionally stable and precise dimensions
- Very high chemical resistance
- Exceptional temperature resistance of very thin wall parts
- High stiffness of even very thin wall applications
- Low coefficient of thermal expansion
- inherently flame retardant
LCP (Liquid Crystal Polymers) allow super fast injection moulding cycles , particularly in thin sections due to its unique structure.
LCP often outperforms ceramics or thermosets at complex thin-walled applications requiring superior heat aging performance. Parts moulded from LCP exhibit very high dimensional stability even when heated up to 200 - 250°C. Heat deflection temperature (HDT) of some LCP (Liquid Crystal Polymers) grades reaches up to 300°C.
LCP (Liquid Crystal Polymers) are available:
- Glass fibre reinforced
- Carbon fibre reinforced
- Mineral filled
- Filler/fibre combinations
- Graphite filled
LCP is usually selected for a specific application or a specific market sector based on its key properties.
Typical LCP applications:
- Different electronic and electrical components
- Lighting applications
- Fuel and gas barrier structures
- Stainless steel substitution at medical devices
