Can polyethylene wax be used in rubber? In addition to using relevant machinery during rubber processing, certain rubber processing additives also need to be added. Existing rubber processing additives include polyethylene wax, montan wax, etc., which have excellent performance in the rubber processing process.

Polyethylene wax has different functions in different processes of rubber processing: Polyethylene wax can enhance the diffusion of fillers in rubber processing, increase the extrusion rate, increase the mold flow rate, and facilitate demoulding.

1. Rubber mixing: divided into plasticizing and mixing. Masticating is defined as reducing the molecular weight, increasing plasticity, improving processing performance, and producing a masticated rubber that meets the plasticity requirements. Mixing is defined as the uniform mixing and dispersion of rubber and compounding agents to form a rubber compound. The equipment used is open mixers, internal mixers and extruders.

2. Calendering: It can produce pure glue, patterned glue, and coating (gluing, gluing) of curtains, canvas, copper-plated steel wire curtains and other frame materials.

3. Extrusion: Continuously extrude semi-finished products with different cross-sections such as hoses, profiles, strips, rubber sheets, etc. through different shapes for molding and direct vulcanization.

Polyethylene wax can enhance the dispersion of fillers in rubber processing, improve the kneading and molding speed, increase the mold flow, facilitate demoulding, and improve the surface gloss of the product.

PE wax can also be used as a processing modifier for plastics and elastomers, ink slurry polishers, paper coatings and candles. PE wax often plays an unimaginable anti-sedimentation role in floor paints. Its structure is made by free radical polymerization of alkene and other monomers under high pressure. It can also be produced by degradation reaction. . As a lubricant, polyethylene wax has stable chemical properties and good electrical properties. PE wax is increasingly used in work.
