PRODUCT INTRODUCTION

Chlorinated polyvinyl chloride (CPVC) is a product of further chlorination modification of polyvinyl chloride (PVC), and its chlorine content is generally 65% ~ 72% (volume fraction). In addition to many excellent properties of PVC, CPVC has much better corrosion resistance, heat resistance, solubility, flame retardancy, mechanical strength, etc. than PVC. Therefore, CPVC is a new material with excellent performance and is widely used in construction, chemical industry, metallurgy, shipbuilding, electrical appliances, textiles and other fields, with a very broad application prospect.

PRODUCT PROPERTIES

Chlorinated polyvinyl chloride is made by chlorination modification of polyvinyl chloride (PVC) resin and is a new type of engineering plastic. The product is white or light yellow, tasteless, odorless, non-toxic loose particles or powder. After chlorination of PVC resin, the irregularity of molecular chain arrangement increases, the polarity increases, the solubility of the resin increases, and the chemical stability increases, thereby improving the heat resistance of the material and the corrosion resistance of acids, alkalis, salts, oxidants, etc. Improve the mechanical properties of the heat deformation temperature of the resin, the chlorine content is increased from 56.7% to 63-69%, the Vicat softening temperature is increased from 72-82℃ to 90-125℃, the maximum use temperature can reach 110℃, and the long-term use temperature is 95℃. Therefore, CPVC is a new type of engineering plastic with broad application prospects.

PRODUCT USE

Also known as (poly) perchlorethylene. A polymer compound obtained by chlorination of polyvinyl chloride. Chlorine content is 61%~68%. It is thermoplastic. White powder. Not easy to burn. Resistant to concentrated acid, concentrated alkali solution, mineral oil, etc., the product does not deform in boiling water. It is more soluble in organic solvents such as esters, ketones, aromatic hydrocarbons, etc. than polyvinyl chloride. Used to make corrosion-resistant paints, adhesives and synthetic fibers, etc.

CPVC has excellent high temperature resistance, corrosion resistance and flame retardancy, and compared with other thermoplastic engineering plastics, the price is relatively low. Therefore, CPVC has a wide range of uses. It is widely used in hot and cold water transportation in residences, hotels, and restaurants, as well as industrial pipeline water supply systems; building materials such as cable tubes, special-shaped doors and windows; decorative materials in aircraft, and materials for cars and lamps; CPVC sheets can be welded into different equipment; in addition, it is also widely used in the electronics industry.
