The Difference Between MDI And TDI
Both TDI and MDI are a kind of raw material in polyurethane production, and they can replace each other to a certain extent, but there are no small differences between TDI and MDI in terms of structure, performance and subdivision use. 1. The isocyanate content of TDI is higher than that of MDI, ...Read more -
Have You Encountered The Following Problems When Sparying Polyurethane?
Polyurethane spraying is high pressure polyurethane spraying equipment. Because the material of the high-pressure spray equipment is slammed into a small mixing chamber and spun vigorously at high speed, mixing is very good. The material moving at high speed forms fine mist droplets at the nozzle...Read more -
The Difference Between TPU And Rubber
TPU (Thermoplastic polyurethanes) is a material between rubber and plastic. The material is oil and water resistant and has excellent load-carrying and impact resistance. TPU is an environmentally friendly non-toxic polymer material. Tpu material has the advantages of high elasticity of rubber an...Read more -
Have You Encountered The Following Problems In The Process Of Polyurethane Foaming?
Polyurethane foam is a high molecular polymer. A product made from polyurethane and polyether that has been expertly mixed. So far, there are two types of flexible foam and rigid foam on the market.
