Polyester - Based TPU Rubber Coating Thermoplastic Polyurethanes Granules Raw Materials With Abrasion Resistance And Flexibility

Polyester-based TPU and polyether-based TPU differ significantly in their compositions, properties, and applications. Here's a concise description of their distinctions:

Composition:

• Polyester-based TPU primarily consists of raw materials such as 4,4'-diphenylmethane diisocyanate (MDI), 1,4-butanediol (BDO), and adipic acid (AA). The MDI content is approximately 40%, AA accounts for about 35%, and BDO comprises around 25%.
• Polyether-based TPU, on the other hand, is primarily composed of MDI, polytetrahydrofuran (PTMEG), and BDO. The MDI content is roughly 40%, PTMEG constitutes about 40%, and BDO makes up approximately 20%.

Properties:

• Polyester-based TPU exhibits excellent mechanical properties, wear resistance, tear resistance, chemical resistance, high temperature resistance, and ease of processing. However, its hydrolysis resistance is relatively poor.
• Polyether-based TPU boasts superior low-temperature flexibility, hydrolysis resistance, mold resistance, UV resistance, and a good feel. However, its peel strength and tensile strength are relatively lower compared to polyester-based TPU.

Applications:

• Due to its robust mechanical properties and wear resistance, polyester-based TPU is widely used in applications such as oil pipes, seals, automotive parts, conveyor belts, footwheels, shoe materials, injection molding parts, and blended modified materials.
• Polyether-based TPU, with its excellent low-temperature flexibility and hydrolysis resistance, is ideal for use in thick-walled extruded profiles, protective clothing, waterproof jackets, flame-retardant materials, and other applications where resistance to hydrolysis and flexibility at low temperatures are crucial.

Utilizing polyester-based TPU for rubber coating offers numerous advantages. Its robust tensile strength and tear resistance provide exceptional durability, ensuring that the coating withstands wear and tear over extended periods. The material's excellent flexibility and elasticity allow for a wide range of motion without cracking or breaking, maintaining performance in dynamic applications. Polyester TPU's resistance to chemicals, oils, and greases offers superior protection against contaminants, preserving the integrity of the coated surface. Furthermore, its ability to adhere well to various substrates enhances the coating's bond strength and reliability. Overall, polyester TPU rubber coatings provide durable, flexible, and protective solutions for a wide range of industrial and commercial applications.
