PVC resin is a less stable polymer rigid pvc plastic products, will degrade under the action of light and heat, the process is hydrogen chloride evolution, structural changes occur, but the extent of relatively light. At the same time when a mechanical force, oxygen, odors, HCl and some of the active metal ions accelerate decomposition. PVC resin after removing HCl rigid pvc plastic prices, produced in the main chain of conjugated double-stranded rigid pvc plastic, the color will change. With the increase in the number of hydrogen chloride decomposition, polyvinyl chloride resin, the original white to yellow, pink, red, brown and even black. PVC for most inorganic acids and bases are stable, heat is not dissolved but is divided interpreted hydrogen chloride. Azeotroped with potassium hydroxide to obtain a brown insoluble unsaturated products. PVC solubility and molecular size and polymerization methods. Generally the solubility of the polymer with increasing molecular weight decreases Qingdao rigid pvc plastic, resin emulsion method than the resin suspension poor solubility. It can be dissolved in ketones (such as methyl hexyl ketone, cyclohexanone), aromatic solvents (e.g. toluene, xylene), dimethylformamide, tetrahydrofuran. Polyvinyl chloride resin at room temperature is almost insoluble plasticizer, significant swelling at high temperatures, even to dissolve. PVC material is not easily flammable, high strength, resistance to climate variability and excellent geometric stability. PVC oxidant, reductant and acid has a very strong resistance. However, it can be concentrated oxidizing acids such as sulfuric acid, concentrated nitric acid corrosion and does not apply to contact with aromatic hydrocarbons, chlorinated hydrocarbons occasions.
