Crospovidone Sds25249-54-1

Organic peroxidecrospovidone sds is structurally different from thermoplastics, thermosetting resins and vulcanized rubber. It has a body structure but is not completely cross-linked. The cross-linked area is small and does not have a large cross-linking network like vulcanized rubber. In terms of performance, it has the characteristics of all three, that is, it has both thermoplasticity, hardness, good solvent resistance, high elasticity and excellent low temperature resistance. Whether it is high-density polyethylene or low-density polyethylene, after crosslinking, its tensile strength, heat resistance, aging resistance and weather resistance, dimensional stability, stress crack resistance, abrasion resistance and solvent resistance are all Improved, and excellent creep resistance. The softening point of cross-linked polyethylene can reach 200℃, and the heat resistance can reach 140℃. In addition, it also has excellent electrical insulation, low temperature resistance and radiation resistance. The properties of peroxide cross-linked polyethylene.

Properties: white or milky white free-flowing powder, easy to absorb moisture, odorless or slightly odorous, insoluble in water, alkali, acid and commonly used organic solvents, with strong swelling performance and complexation ability with many types of substances.

Application: Due to the high molecular weight and cross-linked structure of cross-linked povidone, it is insoluble in water but can quickly promote the expansion of its network structure and disintegrate when exposed to water, and is widely used as a disintegrant for tablets in medicine, and is widely used as a suspension stabilizer, a complexing agent for pharmaceutical ingredients, and a complexing agent for tannins and polyphenols in plant drugs
