It supports injection molding and extrusion processing with excellent process ability, stable forming and high tear-proof property. Ideal for casual shoes, sports shoes and various footwear outsoles, it delivers comfortable foot feel and long service life, meeting mass production needs of footwear manufacturers with consistent quality.
Compliant with international environmental standards, this material is free from harmful substances, ensuring safety for both production workers and end-users. Its consistent batch-to-batch quality guarantees stable performance in large-scale manufacturing, reducing production errors and material waste. The granules also exhibit good compatibility with common additives, allowing for easy customization of colors and specific functional properties to meet diverse design requirements of footwear brands.
Relationship Between TPR-SOLE-85A VS TPU
TPR-SOLE-85A is a thermoplastic rubber compound for shoe soles, while TPU is thermoplastic polyurethane. Both are elastic and processable thermoplastics widely used in footwear, but they belong to different material systems.
TPR-SOLE-85A is primarily composed of blends of styrene-butadiene rubber (SBR) and polypropylene (PP). This composition gives it a soft, rubber - like feel, along with excellent flexibility and resilience. As a result, it is particularly suitable for casual shoes and sports shoes that require a comfortable and cushioned wearing experience.
In contrast, TPU is a polymer formed by the reaction of diisocyanates and diols. It offers higher hardness, better wear resistance, and superior oil and chemical resistance. It is often used in high-performance footwear components, such as out soles, that demand durability and support.
Additionally, TPR-SOLE-85A generally has a lower density compared to TPU, which contributes to lighter shoe weights. Meanwhile, TPU provides better dimensional stability and heat resistance, maintaining its properties even under higher temperature conditions during processing or prolonged use.
