Overview of Liquid Crystal Polymer (LCP) including background, history, advantages, limitations and typical applications.
|
|
Background: 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.
