Publish Time: 2026-07-08
TPU Granules are a polymer material that combines the elasticity of rubber with the processing properties of plastics. They possess excellent properties such as abrasion resistance, oil resistance, high elasticity, and tear resistance, and are widely used in automotive parts, electronics, medical devices, sporting goods, cable sheathing, and industrial products. In many applications, products need to be exposed to humid, high-temperature, or high-moisture environments for extended periods. If the material's hydrolysis resistance is insufficient, performance degradation, aging, and even cracking can easily occur.1. Enhanced Material Stability Through Hydrolysis ResistanceHydrolysis is the process by which the molecular chains of polymer materials break down under the combined influence of moisture and heat, leading to decreased material strength, reduced elasticity, and shortened lifespan. TPU Granules, through optimized polymer molecular structure and the use of hydrolysis-resistant formulations, effectively reduce the impact of moisture on the material's internal structure, allowing the product to maintain good physical properties even after prolonged exposure to humid air or water environments. A stable molecular structure reduces material performance degradation and improves the long-term reliability of the product.2. Maintaining Excellent Mechanical PropertiesMany products manufactured using TPU Granules need to withstand continuous stretching, bending, friction, and impact, making the maintenance of mechanical properties crucial. TPU materials with good hydrolysis resistance maintain high levels of tensile strength, tear resistance, and resilience even in prolonged high-humidity environments, and are less prone to hardening, brittleness, or cracking due to moisture erosion. This not only improves product durability but also reduces repair and replacement costs caused by material aging.3. Meeting Application Needs in Complex EnvironmentsIn industries such as automotive, wire and cable, industrial equipment, and outdoor products, products often face complex environments including high humidity, high temperature, rain, or thermal cycling. Hydrolysis-resistant TPU Granules can adapt to these application conditions, providing continuous and stable performance assurance for products. For example, in applications such as automotive wiring harness sheathing and industrial hoses, the material can resist moisture erosion for extended periods, maintaining flexibility and sealing performance; in sporting goods and outdoor equipment, it can also reduce the adverse effects of environmental changes on product performance, extending overall service life.4. Optimized Processing Performance Enhances Product QualityIn addition to excellent hydrolysis resistance, TPU Granules also possess good processing performance, suitable for various molding processes such as injection molding, extrusion, and blow molding. The hydrolysis-resistant formulation maintains stable physical properties while ensuring processing flowability, resulting in more stable product dimensions and a more uniform surface quality. For high-performance products requiring long-term use, this stable processing performance helps improve product consistency and meet the quality requirements of automated production and mass manufacturing.5. Driving Continuous Upgrading of High-Performance MaterialsWith the continuous development of industries such as new energy vehicles, smart electronics, medical equipment, and outdoor gear, the market has placed higher demands on material durability and environmental adaptability. Through continuous optimization of hydrolysis resistance, TPU Granules not only meet the needs for long-term stable use in humid environments but also combine wear resistance, oil resistance, weather resistance, and environmental friendliness to provide reliable material support for more high-end products. In the future, with continuous advancements in material modification technology and manufacturing processes, hydrolysis-resistant TPU Granules will demonstrate broader application value in more fields.In summary, TPU Granules, with their excellent hydrolysis resistance, effectively improve the long-term stability of products in humid environments and play a crucial role in maintaining mechanical properties, adapting to complex working conditions, and optimizing processing quality. As the demand for high-performance materials continues to grow, hydrolysis-resistant TPU Granules will continue to provide more reliable and durable material solutions for industries such as automotive, electronics, industrial, and consumer goods.
