Formosa Plastics Polypropylene Chloride Resin PVC Fog Flour C1250M

Products Composition

Polyvinyl chloride resin (PVC), English name Polyvinyl Chloride, is made of chlorine A polymer formed by free radical polymerization of ethylene monomer, with a chlorine content of about 57wt%.

PVC is one of the earliest resins to realize industrialization. It is cheap, and its usage in construction materials, people's livelihood and other application fields is increasing day by day, and its demand is increasing rapidly. It is one of the five general-purpose resins.

Products Features

1. PVC molecules are winding structures and contain polar groups of chlorine atoms, which make The intermolecular forces are strong, and this structure improves the rigidity, hardness, and mechanics of PVC processed products, and endows them with excellent flame retardant properties.

2, PVC resin main chain contains chlorine atoms between two adjacent carbon atoms And hydrogen atoms, causing PVC to easily degrade under the action of light and heat to form hydrogen chloride (HCL) gas.

3. PVC performance:

(1) General performance:

PVC is a white powder with a relative density of 1.35-1.45 (g/cc), The softness and hardness of the processed products can be made into products with widely different softness and hardness by the amount of plasticizer added during processing.

(2) Mechanical properties:

The tensile strength of PVC increases with the increase of the degree of polymerization, but PVC The amount of plasticizer added in different materials has a great influence on the mechanical properties. Generally speaking, as the content of plasticizer increases, the mechanical properties decrease, but the elongation at break increases.

(3) Thermal properties:

The glass transition point temperature of PVC is 80-86℃, and the temperature of PVC resin is 140℃ That is to say, it begins to decompose and produce HCL, which accelerates rapidly to 180°C. Generally, the melting temperature of PVC is 160°C.

(4) Electrical properties:

PVC is a kind of excellent electrical insulation, the volume impedance value is higher than 10^ 14, but the volume impedance is easily affected by the types of processing additives and additives.

(5) Chemical resistance

PVC is resistant to most inorganic acids (except oleum and concentrated nitric acid), Alkali, most organic solvents (ethanol, gasoline and mineral oil) and inorganic salts, suitable as chemical resistant materials. However, PVC is easy to swell or dissolve in esters, ketones, aromatic hydrocarbons and halogenated hydrocarbons, and the best solvents are tetrahydrofuran and nitrobenzene.

Products Advantages

PVC quality is stable, PVC supply is stable, and it complies with international environmental regulations.
