Liquid Crystal Polymer (LCP) Plastic

Liquid Crystal Polymer (LCP) - Manufacturers - Materials - Classification
Liquid Crystal Polymer (LCP) - A relatively unique class of partially crystalline aromatic polyesters based on p-hydroxybenzoic acid and related monomers. Liquid crystal polymers are capable of forming regions of highly ordered structure while in the liquid phase. However, the degree of order is somewhat less than that of a regular solid crystal. Typically LCPs have outstanding mechanical properties at high temperatures, excellent chemical resistance, inherent flame retardancy and good weatherability. Liquid crystal polymers come in a variety of forms from sinterable high temperature to injection moldable compounds.
A number of liquid crystal polymers (LCPs) were produced in the 1970s which displayed order in the melt (liquid) phase analogous to that exhibited by non-polymeric liquid crystals. However, the commercial introduction of liquid crystal polymer resins did not occur until 1984, at that time liquid crystal polymers could not be injection molded. Today, liquid crystal polymers can be melt processed on conventional equipment at fast speeds with excellent replication of mold details and efficient use of regrind.
