Physical and Chemical Properties | The natural color is yellowish translucent with luster. The transparency is better than that of polyethylene and Polyphenylene, but worse than that of polystyrene. With the different amount of additives, it is divided into soft and hard polyvinyl chloride. Soft products are soft and tough, feel sticky, and the hardness of hard products is higher than that of low density polyethylene and lower than that of polypropylene, the phenomenon of whitening occurs in the bend.

The appearance is white spherical particles, the surface is smooth, the internal porosity is high and uniform, the apparent density is large, the dry flow is good, and the plasticity is easy.
Jinxi Research Institute of Chemical Technology. First, distilled water (180 parts), dispersant (0.1-0.06 parts) and other auxiliary agents (appropriate amount) were added to the polymerization vessel, and after purging with nitrogen, vinyl chloride monomer (100 parts) was added. Stir for 15 min, warm up to 55 °c, and stir continuously to
The reaction was stopped when the polymerization pressure decreased by 0.15 MPa, and the final product was obtained by post-treatment.
PVC spherical resin is a new upgrade of PVC resin, suitable for the production of hard pipe, especially large diameter pipe.
resin production raw materials, the skin and mucous membranes of the human body have different degrees of stimulation, can cause skin allergic reactions and inflammation; At the same time also pay attention to the harm of resin dust on the human body, long-term inhalation of high concentrations of resin dust, can cause lung lesions. Most of the resin has a common hazard characteristics: open flame, high temperature flammable, and oxidant exposure will cause combustion risk, therefore, the operator to improve the operating environment, the operating area and the non-operating area shall be intentionally drawn apart, automated and closed as far as possible, and ventilation facilities shall be installed. Packed in plastic film-lined bags or polypropylene woven bags, each 25kg. Storage in a cool, dry, ventilated warehouse, not in the open air, not by sunlight. In the wet and hot season to be inverted once a month, easy to ventilation. When transport must use a clean tarpaulin transport, to prevent moisture. Storage and Transportation period of 1 year is appropriate. Water, sand and fire extinguishing agent are available for fire protection.
The same general-purpose PVC resin, but has better processability, the extrusion rate can be increased by 15% ~ 25%.
