What is the difference between PVC and rubber in the wire?

PVC and rubber are the most commonly used materials for waterproof connector wires, and their price has certain differences with quality, how should we choose.

Different differences

Rubber is a highly elastic polymer material having reversible variable. Elasticity is flexible at room temperature, which can produce a large deformation under small external force, and can restore the original. Rubber belongs to a complete amorphous polymer,
The primary version of PVC is polyvinyl chloride, a vinyl chloride monomer, a referred to as VCM) at the peroxide, azo compound, or the like; or polymerized polymerization of radical polymerization reaction mechanism under light, thermal action .

2. Different from classification

Rubber is divided into natural rubber and synthetic rubber according to feedstock. Rubber: Divided into block raw gelatin, latex, liquid rubber and powder rubber according to form.

PVC is based on the universal PVC resin, high polymerization PVC resin, cross-linking PVC resin; polyvinyl chloride can be divided into four categories: suspension polyvinyl chloride, emulsion polyvinyl chloride, body PVC, solution method is polyvinyl chloride; according to the plasticizer content, PVC is divided into: no plasticizer, the plasticizer content is 0; the hard PVC, the plasticizer content is less than 10%

3. Preparation method

In order to add various desired complex to rubber, rubber first needs to be plasticized to improve its plasticity; then mix the carbon black and various rubber aids and rubber evenly mixed into a rubber; the rubber is passed A certain shape blank is pressed; then it is combined with a textile material (or a metal material) elapsed by a crimping or rubber or rubberized. Finally, it is finally produced by vulcanization and a highly elastic ultimate product. product.

Polyvinyl chloride can be prepared from ethylene, chlorine and catalysts.
