Our production of polyvinyl acetate (food), mainly used in bubble Gum and chewing gum rubber base of raw materials. In addition, industrial aspects: in the glass reinforced plastics, hot melt adhesives, paint, paint, concrete new materials, imported toys, polyurethane materials, textile warp size and adhesive industry also has a wide range of USES, in car bumpers and chimney had been widely used. This product relative to the import of goods, more cost-effective, food grade more safe, reliable, and environmental protection.
in automobile glass fiber reinforced plastic areas, after our factory area of the experiment and the general customers the use. It for car headlamps die casting of the low shrinkage, flow mark and surface brightness all have good performance in the car bumper inside the appropriate to join can improve their low shrinkage and impact resistance ability, reduce their products and brittle. Especially in thin plate glass reinforced plastics processing is to have a good effect.
Our factory is a sino-foreign joint venture enterprises, the production of PVAC USES German craft and technology, products and Germany, the United States of PVAC consistent.
Our product is environmental protection, have issued by the state food safety and environmental hygiene certificate.
Now most of the world USES composite materials are thermosetting, and the use of unsaturated resin (UP) in the hot and solid when serious contraction deformation. YinYang rubber base of YYPVAC low shrinkage additive is for glass reinforced plastics industry SMC, BMC with high temperature of the unsaturated resin (UP), and styrene dissolved after forming die casting, there are serious contraction phenomenon (6-10%) of the professional additives. It can make shrinkage rate reduced from 0.05% to.
It is the main components of polyvinyl acetate, abbreviations PVAC, molecular formula is (C4H6O2) n, concrete numerical value as follows:
