Electronic Injection Molded Parts TPU Granule Raw Materials With Abrasion Resistance

Polyester - Based TPU Electronic Injection Molded Parts 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.

Polyester-based TPU for electronic injection molded parts offers numerous advantages. Its excellent mechanical properties, including high tensile strength and elasticity, ensure robust and durable components that can withstand the rigors of daily use and environmental stressors. The material's resistance to chemicals and temperature fluctuations enhances reliability in electronic applications, safeguarding against performance degradation. Additionally, polyester TPU's processability allows for precise molding, ensuring tight tolerances and a high degree of customization in part design. Overall, it provides a versatile and reliable solution for creating robust, high-performance electronic injection molded parts.
