CR Rubber Compound for Bridge Bearings

The CR Rubber Compound for Bridge Bearings produced by Xiamen SLD Rubber Factory. Our formula possesses weather resistance, aging resistance and mechanical strength. It provides a reliable elastic connection between the upper and lower structures of the bridge, enabling it to bear loads, adapt to deformations and absorb vibrations. As a functional engineering material, it has a long service life and ensures the safe operation of the bridge.

Feature

The CR Rubber Compound for Bridge Bearings gives the impression of being "tough" and "stable". It comes in rolls or blocks, usually dark black in color, uniform in texture, and free of visible impurities or bubbles to the naked eye. Press it with your hand and you can feel that it has both the elasticity of rubber and an inherent sense of firmness. It gives off a faint rubber smell characteristic of industrial materials rather than a pungent chemical odor.

Structure

The structure of this CR Rubber Compound for Bridge Bearings is a complex chemical formula system, not a simple physical form. It takes chloroprene rubber (CR) as the base material and is thoroughly mixed with various additives such as carbon black, vulcanizing agent, antioxidant and plasticizer through an internal mixer.

FAQ

Since CR Rubber Compound for Bridge Bearings is resistant to oil, does that mean there is no need for oil protection?

Although CR rubber has better oil resistance than natural rubber, it is not resistant to ester and ketone solvents, and prolonged immersion in engine oil will cause volume expansion (swelling), thereby altering its mechanical properties.

Is there any unpleasant smell? Can we determine the quality by smelling it?

No, it's not possible. Because it contains chlorine atoms, it has a slightly irritating smell by itself.

Why are there such significant differences in the seller's quotations?

The rubber content refers to the proportion of raw rubber (pure CR) in the rubber compound, with the rest being carbon black, softeners, and other fillers. According to industry standards, the rubber content should be ≥ 55%. Some products with extremely low prices may use recycled rubber or significantly reduce the rubber content, which is prone to aging and deformation, and the lifespan may only be 2-3 years.
