Industry Grade Polyvinyl Chloride Powder

Product Information

Polyvinyl Chloride,referred to as PVC, is the world's third largest output of synthetic polymer plastics (after Polyethylene and polypropylene), the annual production of about 40 million tons of PVC. PVC is vinyl chloride monomer (VCM) in the peroxide, azo compounds, and other initiators, or under the action of light, heat, and other Polymers in accordance with free radical polymerization reaction mechanism. Polymer. Vinyl chloride homopolymer and vinyl chloride copolymer collectively called vinyl chloride resin.Polychloroacetic acid is one of the Industrial Ethylene.
PVC was once the world's most widely produced general-purpose plastic and is used in a wide variety of applications. there are two types of PVC, rigid (sometimes abbreviated RPVC) and soft. Rigid PVC is used for building pipes, doors and windows. It is also used to make plastic bottles, packaging, and bank or loyalty cards. Adding plasticizers makes PVC softer and more flexible. It is used in pipes, cable insulation, flooring, signs, phonograph records, inflatable products and rubber substitutes.
PVC is an amorphous structure of white powder, small degree of branching, glass transition temperature of 77 ~ 90 ℃, 170 ℃ or so began to decompose, poor stability to light and heat, above 100 ℃ or after a long period of exposure to sunlight, it will decompose and produce hydrogen chloride, and further autocatalytic decomposition, resulting in discoloration, the physical and mechanical properties also rapidly decline in practical applications must be added to the stabilizers in order to improve the stability of heat and light. Stabilizer must be added to improve the stability of heat and light in practical applications.
Industrial production of PVC molecular weight is generally in the range of 50,000 ~ 110,000, with a large polydispersity, molecular weight with the decrease in polymerization temperature and increase, no fixed melting point, 80 ~ 85 ℃ began to soften, 130 ℃ into a viscoelastic state, 160 ~ 180 ℃ began to change into a viscous flow state; have good mechanical properties, tensile strength of 60 MPa or so, impact strength of 5 ~ 10kJ/m2; have excellent dielectric properties. PVC is insoluble in common solvents, but will swell in monomer and some chlorinated hydrocarbon solvents.

Company information

The company's main import and export products include

(1)Polymers:The advantage of Polymers is that they can be easily formed into the desired shape using a variety of techniques such as solution casting, melt moulding, or machining. As a result, polymer-based implants are relatively inexpensive to manufacture. Polymers can also react so that different chemical molecules can attach to the surface of the implant, making it more compatible with the body's surroundings.

(2)Flavors and Fragrances:Fragrance: some from the natural world of plants and animals or by artificial single separate, synthetic and get the fragrance material called fragrance. Flavour: Flavour is a mixture of a variety of fragrances (sometimes also containing a certain amount of solvent) blended out of a certain aroma, can be used directly for product fragrance, can be widely used in perfumes, cosmetics, shower gels and other daily necessities. Simply put, flavours are made from a mixture of various fragrances.
