FAQs

We can adjust formulas to meet different needs, such as oil resistance, weather resistance, high temperature resistance, and chemical solvent resistance etc.
The common rubbers we use are NBR, EPDM, SBR, CR, SILICONE, VITON etc.

Yes, the common hardness of the rubber is 70 Shore A.
The range of hardness Shore is from 15 shore A to 90 shore A which depends on different formulas, and the tolerance of hardness is +- 5. Higher number shows harder texture.

Yes, we have special formulas for different colors, but the material property will be worse than black one.

We will suggest material according to the using environment to prolong its service life. Using wrong material will accelerate its aging, hardening, or deforming.

It's called bloom. It's a kind of protection to slow down the outside impact on rubber parts.

The texture of Rubber solid is more like eraser. And the rubber sponge is used for cushion and gap filler.

Both of them are elastic polymer. Silicone with simple ingredients can be used for food or medical industries, and it resists up to 300 ℃ temperature.

Rubber shows good resilience, and it won't melt or become soft at the high temperature. Rubber formula can be adjusted to meet different needs.
Most of the plastic doesn't have elasticity, but it can mix with fiber, talcum to increase its strength. Now we have plastic mixed with rubber polymer, which shows good resilience and strength.

We suggest to analyze it by FTIR in the third-party laboratory. By measuring the specific gravity or flame test, we can roughly identify the material.

Rubber is a kind of thermosetting polymer, which can't be reproduce by melting. But it can be smashed and used as filler in some environmental products, like the ground of playground. Or it can be refined to get carbon as reinforcement in some eco-friendly rubber parts.
