Frequently Asked Questions (FAQ)
Q1: What is the difference between TPR and TR shoe sole materials?
TPR (Thermoplastic Rubber) combines the processability of plastics with the easy-flexing properties of rubber. TR compounds are specific formulations of thermoplastic rubber designed to offer enhanced elasticity, abrasion resistance, and distinct aesthetic finishes suitable for high-quality footwear.
Q2: What range of hardness do these sole materials offer?
The CYS TPR series offers a hardness range of 45-85 Shore A, while the CYR TR compound series provides a hardness range of 50-80 Shore A, allowing for versatile applications from soft, flexible casual soles to firmer, durable outsoles.
Q3: What is the recommended injection molding temperature for these materials?
For the TPR CYS series, the recommended injection temperature ranges from 180°C to 220°C depending on the grade. For the TR CYR series, the recommended temperature ranges from 160°C to 190°C.
Q4: How does density affect the final shoe sole performance?
Lower density grades (such as CYS030 at 0.3-0.35 g/cm³) are ideal for lightweight and cushioned soles, whereas higher density grades (like CYS-010 at 1.0-1.1 g/cm³) provide superior tensile strength and wear resistance.
Q5: What are the DIN Abrasion ratings for the TR compound series?
The CYR TR series features a DIN Abrasion rating of ≤250, ensuring excellent durability and resistance to wear and tear during daily usage.
