Audited Supplier Polyvinyl chloride 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.
1. Good mechanical properties, impact strength is 3~5 times of other films, good folding resistance.
2. oil resistance, fat resistance, resistance to dilute acid, dilute alkali, resistance to most solvents.
3. Can be in 55-60ºC temperature range of long-term use, short-term use can withstand 65ºC high temperature, can withstand -70ºC low temperature, and high and low temperature has little impact on its mechanical properties.
4. Low permeability of gas and water vapor, both excellent resistance to gas, water, oil and odor performance.
5. High transparency, can block ultraviolet rays, good luster.
6. Non-toxic, tasteless, good health and safety, can be directly used for food packaging.
