1. Different ingredients
① Rubber material: Natural rubber is made of latex, and part of the non-rubber components contained in the latex remain in the solid natural rubber. Generally, natural rubber contains 92%-95% of rubber hydrocarbons, while non-rubber hydrocarbons account for 5%-8%. Due to different production methods, different production areas and even different rubber picking seasons, the proportions of these components may vary, but they are basically within the range.
② PVC material: polyvinyl chloride, referred to as PVC (Polyvinyl chloride) in English, is an initiator of vinyl chloride monomer (VCM) in peroxides, azo compounds, etc.; or press under the action of light and heat. A polymer produced by a free radical polymerization mechanism. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.
2. Different uses
① Rubber material: not only provide people with daily, medical and other light industrial rubber products that are indispensable in daily life, but also provide various rubber production equipment or rubber products for heavy and emerging industries such as mining, transportation, construction, machinery, electronics, etc. part. It can be seen that the rubber industry has a wide variety of products, and the backward industry is very broad.
② PVC material: PVC was once the largest general-purpose plastic in the world, and was widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, etc.
