Liquid Crystal Polymer (LCP) is a class of highly crystalline thermoplastics .
Contain benzene rings in polymer chains, which are rod-shaped structures organized by large parallel matrices.
Distinctive features: This material is characterized by lightness and durability. [one]
Due to the low viscosity of the LCP melt, plastic easily fills very thin walls, which makes it possible to manufacture products of complex shapes by injection molding. Dimensional accuracy is ensured by small (or even zero) shrinkage in the direction of flow, as well as a low coefficient of thermal expansion . The relatively high melting point (about 300 ° C) allows the manufacture of heat-resistant products, for example, for use in medicine (the possibility of sterilization in a steam autoclave) or electronics (the possibility of surface mounting by soldering).
The most famous brands:
- Vectra of the German company Ticona
- DuPont Zenite
- Rogers Ultralam
