New polymer combines high temperature mechanical performance with dimensional stability

29-Apr-09
Victrex Polymer Solutions, a division of Victrex plc (UK) and leading provider of high performance polyketones, has introduced a new proprietary range of products under the name VICTREX® ST™ polymer. According to the company, the innovative new product line is part of the VICTREX PEEK product family and is designed to perform in the most demanding environments, specifically in applications requiring a combination of high temperature, mechanical performance and dimensional stability. The new polymer launches with two grades: STG45 polymer (an unfilled granule grade) and ST45GL30 polymer (a glass-filled granule grade). When compared to other unfilled/unreinforced polymers, the VICTREX ST STG45 grade are said to have improved mechanical performance especially in the temperature range from 150°C to 200°C. Along with improved mechanical performance at such high temperatures, the new range maintains VICTREX PEEK's properties of purity, electrical resistance, chemical resistance, dimensional stability and low permeability, moisture absorption. The new VICTREX® ST polymers are well suited for high temperature environments such as those found in the automotive, oil and gas or electronics industry. The company says that VICTREX ST polymer can be a metal replacement option for seals, disk drive carriers, connectors, turbo charger impellers, rings, test sockets, wire coatings and valve plates.
