TPEE Celanese G3548L

TPEE Celanese G3548L is a low‑modulus thermoplastic polyester elastomer with hardness of 35D. Formulated with non‑discoloring stabilizer, it features high elasticity, excellent low‑temperature resistance, good heat resistance, oil resistance and resistance to various chemicals.

Main Applications

Automotive Industry: Commonly used for brake‑tube seals, seat adjustment components, air‑bag covers, air intake pipes, where low‑temperature resistance and fatigue resistance are critical.

Electrical‑Electronic Products: Suitable for cable sheaths (especially for high‑low temperature resistance requirements), connector protective sleeves, damping pads for small electronic components.

Industrial Parts: Applied for industrial hose‑joint seals, light‑duty conveyor belts, noise‑reducing gears, reinforcement layers for hydraulic hoses.

Consumer & Sporting Goods: Such as grips for sports equipment, roller‑skate wheels.
