Detailed introduction to high quality PVC Resin (Suspension Grade):
PVC RESIN :
We offer a wide range of PVC resin based on it suspension grade which having several applications. PVC resin is mainly available in suspension grade like SG 3 ( K Value 72 - 71 ), SG 5 ( K Value 66 - 68 ) and SG 7 ( K Value 62 - 60 ). We mainly dealing with PVC resin, K 67 (SG5)suspension grade (ethelene based).
Product:PVC Resin Formula:(C2H3Cl)n H.S.CODE: 3904109001 CAS.NO.: 9002-86-2
Properties:PVC resin is a white or buff powder, the apparent density of 0.40 ~ 0.60g/cm3, relatively density 1.4 g/cm3, refractive index of 1.544 (20 C), water absorption ≤ 0.5 %. indissolve in water, alcohol, gasoline, can be swelling or dissolved in ether, ketones, chlorinated aliphatic hydrocarbons and aromatic hydrocarbons. Under 20 C, there is a strong acid-resistance, can be resistant to any concentration of hydrochloric acid, 90% or less of sulfuric acid, 50% ~ 60% of nitric acid and 20% or less of the caustic soda solution, stability of the salts. In the flame will burn on and left flame it will be extinguished. Excellent dielectric insulation properties.
PACKING: 25kg pp woven bag or kraft paper bag (17 MT/20’FCL)
Applications :
1. SG-3: Films, raincoat, industry packing, artificial leather, hose and shoe-making material, etc.2. SG-5: Rigid plate, gramophone record, value and welding rod, PVC pipes, PVC windows, doors ,etc.3. SG-7: Good hardness and high strength, mainly used for hard plastic tubes and pipes, good for bottle, clarity flake etc.
