Bayer's technology

1, polycarbonate polyurethane sandwich composite

Sandwich composites have the characteristics of light weight, high hardness and high impact strength. Traditional composite materials are made of honeycomb or corrugated cardboard sandwiched between glass fiber layers and bonded by polyurethane spraying system provided by Bayer Material Science and Technology. Bayer Materials Science and Technology recently stated that thermoplastics, especially polycarbonate, "best meet the spectral performance standards of expanded polyurethane composites".

2. Nano-porous rigid foam plastics

One of the main research fields of Bayer Material Science and Technology is to make remarkable progress in heat insulation of refrigeration equipment within a few years. It is planned to use brand-new foaming technology and microemulsion to manufacture polyurethane rigid foam with "nano-pores". The size of conventional rigid polyurethane foam parts used in refrigeration equipment is about 65438 0.50 microns.
