Bayer laboratories: the broad application of polyurethane

Polyurethane has a broad application markets. For example, a car seat is made ​​of polyurethane , household refrigerators because the polyurethane have excellent insulation properties. In addition , it is necessary raw cold foam mattress. A polyurethane made ​​by the two liquids , the liquid is poured into the two different models , each reaction and become a foam : finished materials available .Washi tape

Bayer 's technology center , we conducted on rigid and flexible foam production research on chemical formulations to improve and adapt to meet the needs of customers around the world .Wholesale masking tape

Soft molded foam production in the factory, we produce experimental car seat . First production parameters entered into the computer , temperature and mixing ratio are all important factors. Then, the two liquids are mixed , and finally injected into the mold . We see this for the automotive industry ,Sellotape in three steps. The first step and the second step is the lateral sidewalls or bolster support. Polyurethane mixture can be used to generate a more rigid foam , so that we can get a turn while driving the necessary lateral support , or we will slide the seat . And finally into the central region is a relatively soft foam , can provide good seating comfort. The final reaction of the two materials is carried out in the model , let us show you the specific reaction process. Polyol and iso- cyanate ester will react after mixing , almost instantly produce foam. Ultimate use of this material are determined by consumers and not us.Masking tape
