Lehmann & Voss at Chinaplas 2015: To Introduce New Generation of PTFE-modified Polymers

Published on 2015-05-07. Author : SpecialChem

LEHVOSS (Shanghai) Chemical Trading Co., Ltd. will participate in Chinaplas 2015, the 29th International Exhibition on Plastics and Rubber Industries, which will be held on May 20-23, 2015 at China Import & Export Fair Complex, Pazhou, Guangzhou, PR China.

Lehmann & Voss & Co. announces the introduction of LUVOCOM® XTF, a new generation of polymers lubricated with an advanced proprietary PTFE formulation. These new high-performance compounds exhibit significantly increased wear resistance, especially at high loads, when compared to standard PTFE formulations. "By substituting standard PTFE additives with our proprietary lubricant and by optimizing our processing technology, we have been able to substantially elevate wear resistance performance with these new compounds," said Thomas Collet, Product Management, Lehmann & Voss & Co. "The new compounds are an innovation driven by ongoing customers’ demand for higher performance polymers and compounds to meet increased requirements combining high pressure and elevated temperature. This new material technology is opening up opportunities in automotive, industrial and oil and gas market applications, as well as high precision machined components via stock shapes." Unlike traditional PTFE-modified compounds that can have decreased performance and insufficient wear resistance at higher loads, the new LUVOCOM XTF compounds significantly improve wear resistance and provide low co-efficient of friction while preserving mechanical performance.

Benefits include short running-in behavior. "OEMs like to have a short running-in phase," explained Collet. "Otherwise their customers can experience a major disruption, or even a failure, in a dynamic system." An additional benefit is less deposition in tool cavities during injection molding. "Because of the improved mechanical properties, the specially formulated PTFE doesn’t separate from the polymer during the injection molding process," said Collet. The first compounds in the LUVOCOM XTF series are based on PEEK (polyetheretherketone) polymer. Under high loads, PEEK compounds with XTF modification exhibit significantly lower levels of wear: 50% less than unreinforced PEEK and 80% less than PEEK modified with 15% standard PTFE. "For example, in combination with aramid fibers, LUVOCOM XTF provides superior wear resistance while still showing robust mechanical properties in addition to a low coefficient of friction," added Collet. The initial products offered in this new series are LUVOCOM 1105-9098/XTF and 1105-9182/XTF based on PEEK. Other polymer formulations are in development.

About Chinaplas 2015


Chinaplas 2015 is organized by Adsale Exhibition Services Ltd. and co-organized by China National Light Industry Council - China Plastics Processing Industry Association, China Plastics Machinery Industry Association, Guangdong Plastics Industry Association, Messe Düesseldorf China Ltd., the Plastic Trade Association of Shanghai and Beijing Yazhan Exhibition Services Ltd. The event is also supported by various plastics and rubber associations in China and abroad. First introduced in 1983, Chinaplas is China's only plastics and rubber trade show approved by UFI (The Global Association of the Exhibition Industry). Chinaplas has been exclusively sponsored by the Europe's Association for Plastics and Rubber Machinery Manufacturers (EUROMAP) in China for the 26th time. Chinaplas is one of the top ranked Asia's and world's plastics and rubber trade fairs.

Chinaplas 2015 is expected to have 3,200 exhibitors from 40 countries and regions, together with13 pavilions from countries and regions of Austria, Canada, France, Germany, Hong Kong, Italy, Japan, Korea, PR China, Switzerland, Taiwan, UK, USA, occupying an exhibition area of over 240,000 sqm, to showcase their diversified chemicals and raw materials and over 3,200 sets of plastics and rubber machineries. The 4-day exhibition is expected to attract over 120,000 trade visitors from 130 countries or regions.
