Polyethylene wax can be used as a rubber processing aid, which can enhance the diffusion of fillers, improve the extrusion molding rate, increase the flow rate of the mold, and facilitate the demoulding. Let's take a look at the specific use of polyethylene wax as a rubber processing aid.

1. Anti-ozone aging: polyethylene wax will precipitate the rubber surface to form a protective film.

2. plasticizing, improve processing performance: polyethylene wax molecular weight is much lower than rubber, after adding its molecular chain is easy to enter the rubber molecular chain, so that the rubber molecular chain is easier to slide.

3. Lubrication: improve extrusion performance and reduce shrinkage.

4. Make the rubber easier to mix evenly: polyethylene wax enters the rubber molecular chain, expands the distance between the rubber molecular chains, and at the same time carries low-molecular compounding agents such as rubber molecular chains, making it easier for other compounding agents to disperse.

In addition, PE wax as PVC pipe, shaped material, film, wire and cable and other plastic and rubber processing aids. PE waxes can also be used as a slip and release agent for polyolefins and PVC. PE wax can improve the fluidity of polyethylene, polypropylene, ABS and polymethyl methacrylate and polycarbonate release characteristics.
