TDI Polyurethane Prepolymer

TDI polyurethane prepolymer produced by Shandong XinRuiTuo Precision Industry Co., Lted. is a high-end product. After the product is formed, it has the remarkable characteristics of wear resistance, oil resistance, vibration absorption, solvent resistance, high mechanical strength, tensile resistance and tear resistance.

Our company has been engaged in TDI, MDI, PPDI, ND and other high-tech elastomer industries since 2006. From the beginning, we have been committed to the R&D, production and sales of TDI polyurethane prepolymer. After a period of accumulation, we have not only broadened the product line, but also improved the product quality step by step. We firmly believe that quality determines the fate of a production-oriented company. After so many years of development, with our rich experience, professional technology and national influence in the polyurethane industry, more manufacturers from home and abroad have learned about the advantages and benefits of high-quality polyurethane elastomers.

We have various types of TDI polyurethane prepolymers, please refer to the following table for details:

• Polyester T100 type prepolymer：

• Polyester T80 type prepolymer：
