Packaging and transportation: Packed in an outer composite kraft paper woven bag. The net content of each bag is 25kg. It is strictly forbidden to used sharp tools during transportation, loading and unloading, so as to damage the packaging bags.
What Is PVC Resin SG5 K66-68
In industrial fields, the viscosity or K value is commonly used to express the average molecular weight or average degree of polymerization. The molecular weight of the resin is related to the physical and mechanical properties of products. The higher the molecular weight, the higher the tensile strength, impact strength and elastic modulus of products, but the fluidity and plasticity of the resin melt decrease. At the same time, different synthesis processes lead to differences in the shape of the resin. The most common one is the loose resin produced by the suspension method, commonly known as SG type PVC resin. SG5 PVC resin the K value of 66-68 absorbs plasticizers quickly, and the plasticizing speeding is fast.
