High ethylene content for excellent compression set resistance and dimensional stability.
Optimized diene type and level enabling superior sulfur and peroxide cure compatibility.
Consistent batch-to-batch quality supported by Sinopec’s ISO 9001-certified production system.
Low extractables and low volatility, meeting stringent automotive interior air quality requirements (e.g., VDA 278).
Enhanced processability in extrusion and injection molding due to balanced Mooney viscosity (ML1+4 @ 125°C ≈ 50–55).
Automotive weatherstrips and door seals requiring long-term sealing performance at extreme temperatures.
Roof membrane systems for commercial and residential buildings demanding UV resistance and low-temperature flexibility.
Industrial hose covers and gaskets exposed to hot water, steam, and ozone.
Under-hood engine compartment components including coolant hoses and vibration dampers.
Railway vehicle sealing profiles complying with fire safety standards (EN 45545-2).
