1. High temperature resistance: -20℃ to 120℃ temperature range, especially suitable for pumping high - grade concrete or concrete containing corrosive media to avoid piston failure at high temperatures. 2. Corrosion resistance: Resists chemical corrosion. 3. Excellent sealing performance: Prevents concrete leakage and ensuring pumping efficiency. 4. Anti - aging performance: Long-term elasticity and reducing sealing failure due to hardening.
