Polyester polyols have advantages in temperature resistance, wear resistance, oil resistance and mechanical strength compared with polyether polyols, which are widely used in the market today. Therefore, polyurethane foam materials, synthetic leathers, coatings, adhesives, and elastomers Developed products show their characteristics. In particular, polyether urethane rigid foam materials used in a large number of applications in recent years, adding a certain proportion of polyester polyols, can greatly increase the strength of the material, thereby significantly reducing the production cost of polyurethane hard foam materials; due to the polyester type hair Foam material has small thermal conductivity and excellent thermal insulation performance. It is widely used in pipe insulation and building insulation.
According to reports, the results of the use of waste polyester plastic products as raw materials, not only conducive to environmental protection, but also a simple production equipment and technology, low investment, low cost, product uses a wide range, fast recovery funds; a small amount of chemical solvents used in production can be Recycling basically does not emit pollutants.
