Teleflex Fluid Systems Europe will feature two products for the automotive industry benefiting from DuPont material science at Engine Expo 2005 in Stuttgart, Germany.
Teleflex Fluid Systems Europe (TFSE), a global manufacturer of PTFE hoses and accessories, will feature two products for the automotive industry benefiting from DuPont material science at Engine Expo 2005 in Stuttgart, Germany, 31st May to 2nd June 2005.
Fluorocomp is a patented preformable composite hose with an antistatic DuPont Teflon PTFE fluoropolymer resin barrier layer and a PTFE-impregnated braid for high temperature automotive environments, and the new Tflex fuel vent tubing uses DuPont ETPV to provide a strong and flexible structure for easier assembly and cost savings.
The TFSE stand is in Hall 6, Stand 6050.
Fluorocomp is a fluoropolymer/glass-fibre braided composite product specifically designed to perform well in safety-critical, high temperature automotive environments.
The PTFE-impregnated fibreglass and DuPont Kevlar braid functions as an integral heat-shield, whilst the anti-static Teflon barrier layer used for the inner-tube ensures total compatibility with fuels and oils up to 260C.
Its high bend radius permits simpler and shorter routing paths and easy attachment is enabled through its wide fitting compatibility.
According to TFSE, the extremely low effusion and permeability rates of Fluorocomp help protect the atmosphere.
DuPont ETPV, a new kind of thermoplastic vulcanisate, provides the structure for the Tflext fuel vent tubing from TFSE.
The tubing is a three-layer construction also containing barrier and conductive layers for ultralow permeation, and complies with stricter emission standards soon to be implemented in the USA.
Thanks to the elasticity of DuPont ETPV, the tube is easily and securely installed by pushing it onto barbed connectors, whilst the inherent efficiency of thermoplastic processing technology when using DuPontT ETPV means that TFSE can supply Tflex tubing at a competitive price.
Material strength and flexibility are also contributing factors in the tubing's resistance to kinking.
TFSE, formerly Astraflex, has been supplying Teflon PTFE fluoropolymer media transfer solutions since 1979.
A Teflon brand partner, Engine Expo 2005 represents the company's first representation at an international show.
"Engine Expo is widely perceived as being among the world's leading international exhibitions for key specifiers and suppliers for engine design, component supply and production technology within the automotive, truck and bus engine manufacturing industry".
"We very much hope that our product and technical expertise, combined with the strength and performance of the DuPont Teflon brand, will lead to many interesting and mutually productive discussions", says Dave Redfearn, Group Sales Director for TFSE.
