RF215(Ⅱ)

RF215(Ⅱ)

This product is a solvent-based polyurethane adhesive mainly composed of isocyanate, polyol (polyether type), and solvent. The molecular chain contains urethane groups (-NHCOO-), thus exhibiting high activity and polarity. It demonstrates excellent chemical adhesion to various materials, including porous materials with active hydrogen, such as foam, plastic, wood, leather, fabric, paper, and ceramics, as well as smooth-surfaced materials like metal, glass, rubber, and plastic.

Classification, Synthesis, and Processing of TPU Materials - Guangyuan Ruifeng New Materials

TPU stands for thermoplastic polyurethane, a type of polyurethane that can be plasticized by heating and dissolved by solvents. Compared to blended and cast polyurethanes, thermoplastic polyurethanes have few or no chemical crosslinks in their chemical structure; their molecules are essentially linear, yet there is a certain amount of physical exchange.

Seven ways to improve the heat resistance of PVC plastic

Seven ways to improve the heat resistance of PVC plastic

If the composition of PVC (polyvinyl chloride) copolymer resin with other monomers contains polar or large groups, the heat distortion temperature of the copolymer will increase accordingly, and its heat resistance will be better than that of PVC, resulting in heat-resistant products.

Seven ways to improve the heat resistance of PVC plastic

If the composition of PVC (polyvinyl chloride) and other monomer copolymer resins contains polar or large groups, the heat distortion temperature of the copolymer will increase accordingly, and its heat resistance will be better than that of PVC, resulting in heat-resistant products. The softening temperature of PVC is 78℃, while the softening temperatures of the copolymers vinyl chloride-vinyl chloride, vinyl chloride-methyl methacrylate, and vinyl chloride-acrylonitrile are 100~130℃, 85℃, and 140~150℃ respectively.

Applications of cold-resistant and environmentally friendly plasticizers - Guangyuan Ruìfēng New Materials

Plasticizers are the largest category of auxiliary agents in the modern plastics industry, playing a decisive role in promoting the development of the plastics industry, especially the polyvinyl chloride (PVC) industry. Any liquid organic compound or low-melting solid that can be uniformly mixed with resin without undergoing chemical changes, but can lower the glass transition temperature of the material and the melt viscosity during plastic molding processing, and remains unchanged itself, or although undergoing chemical changes, can be retained in plastic products for a long time and can change certain physical properties of the resin, is called a plasticizer.
