Rubber and its products in the process of processing, storage and use, due to the combined effect of internal and external factors caused by the gradual deterioration of rubber physical and chemical properties and mechanical properties, and finally lose the use value, this change is called rubber aging. On the surface, it is cracked, sticky, hardened, softened, powdered, discolored, and mildew.

Rigid PVC is one of the most widely used plastic materials. PVC material is an amorphous material.
PVC materials are often added to the actual use of stabilizers, lubricants, auxiliary processing agents, colors, impact agents and other additives.
PVC material has non-flammability, high strength, climate resistance and excellent geometric stability.
PVC has a strong resistance to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid, concentrated nitric acid and is not suitable for contact with aromatic hydrocarbons and chlorinated hydrocarbons.

The type of anti-corrosion coating is very richand its application field is also very rich.So when it is used in different fields, it is likely to choose the type of coating is not the same. High chlorinated polyethylene pipeline anticorrosive coating is one of a class of high chlorinated polyethylene resin as anticorrosive base material, with modified resin, plasticizer, rust pigments, solvents and additives composed of a single component heavy anticorrosive coating

Cured rubber is a more frequent problem in the production process of chlorinated polyethylene cable, and this phenomenon is more prominent in summer. The influencing factors are extrusion temperature, steam pressure, coke time of mixing rubber, and the mixing of impurities.

Chlorinated polyethylene still has some characteristics of plastics, and when used for cable extrusion, it still requires a higher plasticizing temperature than traditional rubber. For customers who do not understand the characteristics of CPE, if they do not grasp the appropriate process parameters and follow the traditional rubber extrusion process to produce cables, problems such as too low temperature and poor plasticization will occur.

Chlorinated polyethylene is powdered, easy to absorb moisture for a long time, resulting in excessive moisture, so that products have bubbles or micropores, etc., southern humid climate is more likely to have this phenomenon. In addition, the production of rubber cables is more complex than that of plastic cables, affected by many factors such as equipment conditions, process conditions, operating level, technical level, etc., there are more problems in the extrusion process, and it is not easy to  solve properly.

Rutile titanium dioxide and anatase titanium dioxide are two important types of titanium dioxide, which are currently the most widely used in the market, but the properties of the two are very different.

ACR is the best impact modifier with good overall performance, good processing performance of modified PVC, high tensile strength, modulus, thermal deformation temperature, and excellent weather resistance. In addition to poor weather resistance, MBS is also a PVC impact modifier with good overall performance, especially MBS has a refractive index similar to PVC, and is the only impact modifier used for the processing of transparent impact modified PVC products.
