Polyurethane products, it is one of the company's products, but in the previous article, there are not many introductions in this area, so we still need to understand the content of this aspect. Therefore, in response to this request, the following editor will do this work and explain the content of polyurethane products, so that everyone can understand it better. Before starting the specific content, let's first solve a problem, and then explain some of the content of polyurethane additives, so that everyone can increase some knowledge in this area. What are the differences between polyurethane products and natural rubber? A: Polyurethane, which is a kind of polymer wear-resistant material between rubber and plastic, its wear resistance is 3 to 10 times that of ordinary natural rubber. Its mold is also between ordinary rubber and plastic. Polyurethane auxiliaries, which play an important role in the synthesis and processing of polyurethane, can be said to be indispensable. The main types are: (1) The main types of synthetic auxiliaries are: catalysts and polymerization inhibitors, chain extenders and Chain extension crosslinking agent and diphenylmethanediamine, etc. (2) Modification and operation aids are mainly used to improve the performance and appearance, and some can also improve the operation process, mainly including plasticizers, friction reducers, lubricants, fillers, colorants and mold release agents Wait. (3) Vulcanization aids Mainly refer to vulcanizing agents and accelerators, which are mainly used in kneading polyurethane elastomers. There are mainly three types of isocyanates and organic sulfur peroxides. (4) Stabilizing system additives Mainly to prevent its aging and prolong its service life, there are heat stabilizers, light stabilizers, hydrolysis stabilizers, mildew inhibitors, flame retardants, etc. Company website: https://www.orksealing.com/
