Advantages

Wear-resistant rubber

I Softkill of Yantai Group Wear-Resistant Rubber

Wear-resistant rubber of Yantai Group has a large amount of polymer long chains. It has such characters as strong tensile resistance and high resilience, which effectively improves the performance of wear and corrosion resistance. Compared with ordinary rubbers, rubber of Yantai Group reduces the microstructure damage to the lowest, and maintains the natural features of solid, good elasticity and wear-resistance.

Yantai Group Wear – resistant rubber with high elasticity is different from the hard materials such as cast stone, compounding ceramics, alloy, iron, etc. It can effectively absorb and repulse the impact and friction force, which takes the loss to a minimum, the noise to the lowest, showing the characteristics of softkill.

Wear-resistant rubber

II Resistance to wear and corrosion

The wear resistance index of Yantai Group Wear – resistant Rubber sheet reaches 128%. 1 mm wear experiment shows that Wear – resistant Rubber of Yantai Group which takes 100 hours to wear 1 mm wins out over the other kinds of rubber which takes 13.8 hour and 24 hour respectively to wear 1 mm.

III The service life is longer than other rubber by 2-4 times

Because of the excellent performance of Yantai Group rubber (Tensile strength, wear and corrosion resistance), its service life is longer than other rubber by 2-4 times

Wear-resistant rubber

IV Flexible and convenient cutting, wide application

Cutting and bonding the wear – resistant rubber to meet various shape and surface requirements, according to the need of piping, pipe fittings, hopper, chute, cylinder, and so on.
