Dispersion Grade PVC Resin For General Purpose Plastisols
On the basis of vinyl chloride emulsion polymerization, a relatively new method of vinyl chloride micro-suspension polymerization to make PVC Dispersion Resin was developed, which was industrialized as early as the mid-1960s. The process is as follows: VCM, desalinated water, and emulsifier are first made into a stable emulsion (with a particle size of about 1.0 μm) by mechanical homogenization, and then polymerized (an oil-soluble initiator must be selected). In this production process, special attention should be paid to the following influencing factors: selection of suitable composite emulsifier and particle modifier system; homogenization of the components of the polymerization system; stirring speed; appropriate ratio of water to monomer. The PVC Paste Resin produced by this method has moderate particle size, excellent fluidity, less emulsifier dosage, and improved thermal stability and water resistance of the resin.
Property：
PVC paste resin (PVC) is a large category of polyvinyl chloride resins. Compared with suspension resins, it is a highly dispersible powder. The particle size range is generally 0.1～2.0μm (the particle size distribution of suspension resins is generally 20～200μm. ). PVC paste resin was researched at the IG Farben factory in Germany in 1931, and industrial production was realized in 1937.
In the past half-century, the global paste PVC resin industry has developed rapidly. Especially in the past ten years, production capacity and output have shown a leaping growth, especially in Asia. In 2008, the global total production capacity of paste PVC resin was approximately 3.742 million tons per year, and the total production capacity in Asia was approximately 918,000 tons, accounting for 24.5% of the total production capacity. China is the fastest growing region in the paste PVC resin industry, with production capacity accounting for approximately 13.4% of the total global production capacity and approximately 57.6% of the total production capacity in Asia. It is the largest producer in Asia. In 2008, the global output of paste PVC resin was about 3.09 million tons, and China's output was 380,000 tons, accounting for approximately 12.3% of the world's total output. Production capacity and output rank third in the world.
