High ethylene content for excellent compression set resistance and dimensional stability.
Optimized diene level enabling superior sulfur vulcanization efficiency and crosslink density control.
Consistent batch-to-batch quality ensured by Sinopec Mitsui’s integrated production and QC system.
Low extractables and low volatility, meeting stringent automotive interior emission standards (e.g., VDA 278).
Excellent resistance to heat, ozone, weathering, and polar fluids including brake fluids and phosphate esters.
Automotive weatherstrips and door seals requiring long-term elasticity and UV resistance.
Under-hood gaskets and coolant hoses exposed to elevated temperatures and thermal cycling.
Railway window and door sealing systems demanding low-temperature flexibility down to –45 °C.
Building façade gaskets and expansion joint seals for durable outdoor performance.
