The appearance of the rubber powder is white, light yellow to yellow or amber, translucent, without unpleasant smell, and no impurities are visible to the naked eye. The finer the rubber powder, the better the performance. The finer the rubber powder, the closer the tensile strength, elongation and abrasion of the vulcanized rubber are to those without rubber powder, and the fatigue resistance and crack growth resistance are higher than those without rubber powder. big.

What are the uses of rubber powder in life?

1. Gypsum powder is mainly used in gypsum putty, the prepared liquid can be directly mixed with gypsum powder and stirred to make gypsum putty, and mixed with gypsum powder to make caulking plaster, which is suitable for filling the joints of indoor ceilings.

2. The application of rubber powder in building materials, such as laying sports fields, laying track bed foundations, vibration reduction and noise reduction, etc. Add rubber powder to asphalt products and mix it at high temperature for paving roads and roofs, and the waterproof layer effect is uniform very good.

3. Rubber powder can be used in plastics and mixed with plastics in any proportion. It can be blended with various plastics such as polyethylene, polyvinyl chloride and polystyrene, and the new material made after blending can be processed into various products through molding, lamination, calendering, injection molding and extrusion.

4. In some high-end products, sometimes a small amount of superfine rubber powder is used, which can improve tearing, fatigue and other properties.

5. Process waste rubber powder into 60-80 mesh, directly make activated rubber powder, and directly make rubber products
