UENO LCP® is a thermoplastic polymer developed through unique R&D by Ueno Fine Chemicals Industry, Ltd., and based on our strengths and know-how as a global manufacturer of monomers for liquid crystal polymers.
UENO LCP® is a flame-resistant, environmental-friendly molding material. We respond to a wide range of customer needs with various type of LCP grades having properties such as high-flowability, heat-resistance, high-strength and general-purpose types.
What are LCPs?
Liquid crystal polymers are used as key components in a wide range of applications, including automobiles and consumer electronics/home appliance products such as smartphones, PCs and air conditioners. LCPs are one of typical high-performance materials generally called super engineering plastics.
LCPs have various unique features such as high heat-resistance, excellent moldability and more. The following diagram illustrates the features and characteristics of LCPs, and the reasons why they have come to the fore.
Features of LCP(Liquid Crystal Polymer)
- Has a rigid, rod-like structure.
- Different from soft string-shaped polymers, there are few entanglements of polymer in the molten state, and therefore LCPs has excellent flowability and high orientation in the direction of flow.
- As the polymers solidify along the direction of flow on molding, the smaller dimension change (low shrinkage and warpage) of the molded items have achieved.
- Those properties above mentioned, such as the high orientation and solidification of the molecules along the direction of flow, develop the higher anisotropy to the molded articles.
UENO LCP® Grade Structures
Making use of our ingenuity and strengths as a monomer manufacturer, we have crafted molecular designs that can be adapted to various prescribed properties, and had a wide range of base resin lineup such as the low-melting-point LCP (8100 Series) and the high heat-resistant LCP (6000 Series). We also have a variety of compound grades, made from our LCP resins and fillers such as glass fiber and minerals, and capable of being applied to wide variety of applications.
