Products Description
Polyvinyl chloride PVC is high molecular compounds polymerized by vinyl chloride monomer(VCM) with structural element as CH2-CHCLn,degree of polymerization usually as 590-1500.In the process of re-polymerization ,affected by kinds of factors such as the polymerization process, reaction conditions, reactant composition, additives etc.it can produce eight different types of PVC resin performance is different. According to residual content of vinyl chloride in polyvinyl chloride resin, is can be divided into :commercial grade, food hygiene grade and medical application grade in appearance, polyvinyl chloride resin is white powder or pellet.
Polyvinyl chloride PVC resin is white powder, density is 1.35-1.46g/cm3, apparent density is 0.4-0.65g/cm3, and is insoluble in water, alcohol and gasoline. The decomposition and plasticization temperature of pure PVC resin is very close to each other. When heated to 130-140℃, it will decompose and release hydrogen chloride gas, so it is not possible to process and manufacture plastic products with pure PVC.

Prouduct Application
PVC is mainly used in industry, construction, agriculture, daily life, packaging, electric power, public utilities, medical and
other fields.
For example:
PVC profiles are mainly used for making doors and windows and energy-saving materials
PVC pipe
PVC film
PVC hard materials and sheets:used to make downpipes,drinking water pipes, electric wire sleeves or stair handrails
PVC general soft products: used to make hoses, cables,wires, plastic sandals, shoe soles
PVC packaging materials
PVC siding and flooring
PVC transparent sheet
Medical industry for making goggles, infusion tube, sheet
SG-3 is for films, hoses, leathers, wire cables and other general purpose soft products.
SG-5 is for pipes, fittings, panels,calendaring, injection, moulding, profiles, and sandals.
SG-7 / SG-8 is for bottles, sheets, calendaring, rigid injection and moulding pipes.
