Ticona Introduces Dissipative Acetal Material to Reduce Static Charge in Auto and other Fuel Systems Components
New Grade Meets Fuel Systems Requirements
Celcon CF802 acetal copolymer meets the requirements of the Federal Test Method for Electrostatic Properties of Materials (FTM 101C, Method 4046) and the SAE J1645 Fuel System Electrostatic Charge Standard. It is also approved under General Motors material specification GMN 7830P-POM-041.
Enhanced Polymer-to-Fiber-Reinforcement Bond
The new grade is made with proprietary Ticona technology that forms a tight bond between the fibers and the acetal matrix. This technology allows the acetal to accept fiber reinforcements and still have physical, mechanical, flow and other properties similar to unfilled acetal, e.g., a tensile modulus of 2,790 MPa and a notched Charpy impact strength of 4.5 KJ/m2. The new grade also has excellent chemical resistance and dimensional stability.
Celcon(R) Acetal Copolymer in Automotive Fuel Systems
Celcon acetal copolymer is widely used in automotive fuel applications. A recent 5,000-hour study by Ticona of how commonly used fuel system plastics age when exposed to nine auto fuel blends found that Celcon acetal copolymer was more resistant to oxygenated and non- oxygenated fuels than acetal homopolymer, polyester and aliphatic polyketone at temperatures found in fuel tanks and outside the engine compartment.
