What are the hardness of TPE/TPR?

- Jun 22, 2018 -

The general TPE/TPR hardness adjustment is adjusted by the content of oil, PP, and calcium carbonate. When the amount of PP or calcium carbonate is increased, the hardness increases, whereas if it decreases, the hardness decreases, and the refueling hardness decreases.



What is the hardness of TPE? The problem is very simple. Users who have contacted TPE or those in the industry know that the hardness of TPE is in the range of 0-100 Shore A. In this hardness range, the hardness suitable for your product's requirements can be arbitrarily chosen. Hardness is 0A, 5A, 10A, 15A, 20A, 25A, 30A, 35A, 40A, 45A, 50A, 55A, 60A, 65A, 70A, 75A, 80A, 85A, 90A, 95A, 100A.



0-20 Shore A is a TPE/TPR soft material, most of which are used in adult raw materials or women's sex toys, but some TPE modified materials even reach the hardness of 000 or 0000, which belongs to ultra-soft TPE/TPR materials. Most of them are used Simulation of inflatable dolls.



Some users will be more concerned about price issues. Will TPE/TPR prices with different hardness be affected? More or less influential, but the impact is not significant. The price of TPE is related to factors such as formula, color, and specific gravity.
