1. Nano polyurethane (temperature 150 ℃ polyurethane products)
Characteristics: high strength, high heat resistance, heat resistance than ordinary polyurethane increased by 30 ~ 50.
The nano polyurethane elastomers developed and produced independently by our factory have excellent strength and abrasion resistance, heat, hydrolysis resistance, aging resistance is excellent, it is a new generation of heat-resistant polyurethane elastomers. It can be applied in the ordinary polyurethane products are difficult to adapt to the high temperature, high speed and other harsh conditions; such as oil drilling mud pump bowl, high temperature and high pressure polyurethane seals, textile machinery in the drawing draw roller, textile high-speed wheels, high-speed friction discs (sheet), roller sheet and so on. There is a broad market for high-performance polyurethane applications.
2. High-speed polyurethane roller (￠57mm load 12kg 6000 rpm can work continuously)
Characteristics: high speed resistance, low heat generation, high strength, high abrasion resistance, high durability
This product is a high-strength special polyurethane modified varieties, without butyl hydroxyl components. After special modification of polyurethane elastomer has high elasticity, low coefficient of friction and low hysteresis loss under high speed rolling and high strain conditions. It is characterized by small endogenous heat and is suitable for working at high rotational speeds (above 15~20 m/s or 50~70 km/h). This is a new special high performance polyurethane elastomer. It breaks through the limitations of polyurethane applications at high speeds, and it will greatly broaden the use of polyurethane products.
3. High-performance polyurethane products (polyurethane cylinder blanks, polyurethane seals)
Characteristics: high-strength, high-pressure resistance, high durability
In response to a variety of shortcomings of the ordinary pu products, we use more advanced raw materials and special production processes, the production of the seals of the performance of the special rubber not only has the physical properties of the casting rubber, the advantages of the permanent deformation of small, but also the molding of thermoplastic. Advantages, and thermoplastic molding process is good, product quality and stability of the advantages, is the perfect combination of tpu and cpu two kinds of technology and technology. The resulting high-performance pu sealing ring heat resistance and aging resistance is excellent, the inner quality of the product and the appearance of the quality has reached a high level.
4. solvent-resistant polyurethane (solvent-resistant products, solvent-resistant prepolymer)
Characteristics: resistance to ethyl ketone, and other ketone solvents
Ketone is the nemesis of ordinary pu products, we have adopted a more advanced raw materials in order to improve the performance of this process and a special production process, to produce injected with good physical properties, ketophilicity of the advantages of a low, solvent resistant coefficient has reached the international advanced level. The solvent resistance coefficient reaches the international advanced level. The product can be used in the printing industry in large quantities.
