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:

• Unfilled
• 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
• Sensors
• Ovenware
• Stainless steel substitution at medical devices
