2024年10月23日 · Here are the specific hardness ranges for TPE: - TPE (TPR) hardness range: 0~100A. Soft materials are typically 0~20A, with commonly used hardness ranging from 30~80A. Higher hardness levels can reach 90~120A. - TPU hardness range: Usually 70A~98A, although some manufacturers can achieve 60A, but at a higher cost. - TPEE hardness range: 28D~80D.

2017年9月19日 · What is Shore Hardness and How is it Measured? The Shore Hardness scales were created to provide a common reference point when comparing different materials. Shore Hardness is measured using a durometer gauge, which uses a spring loaded steel rod to compress the surface of the TPE sample and provide a reading.

2017年6月7日 · In the world of TPEs, touch, or haptics, is one of the key criteria designers use when choosing to use a TPE. Hardness in the TPE world is usually measured on the “A” scale from 0 Shore “A” to 90 Shore “A”. TPE materials harder than 90 Shore “A” are typically measured on the “D” scale.

2024年9月24日 · 对于TPE等软质材料而言，硬度的测量常采用邵氏硬度计 (Shore Hardness Scale)，其中A型和D型是最常用的两种。 邵氏A主要用于测量非常软的物质，如橡胶和某些TPE，而邵氏D则适用于较硬的材料。

The hardness of a material is often one of the first criteria considered when choosing a thermoplastic elastomer (TPE). GLS produces standard products ranging in hardness from 3 Shore A (softest) to 95 Shore A (hardest).

Shore Hardness is measured using a durometer gauge, which uses a spring loaded steel rod to compress the surface of the TPE sample and provide a reading.

One of the key factors to consider when selecting a thermoplastik elastomer (TPE) is the material's relative softness or hardness. Hardness is also related to other important design characteristics such as tensile and flexural modulus.

ISO 48-4 and ASTM D2240 are standards for measuring the hardness of rubber and similar materials using a durometer. ISO 48-4 focuses on vulcanized or thermoplastic rubber and defines four specific scales, while ASTM D2240 covers a broader range of materials and twelve scales.

One of the key properties to consider when selecting a TPE is the degree of hardness required. Hardness can be defined as a material’s resistance to permanent indentation and Durometer is one of several scales used to measure hardness.

The Rockwell scale measures hard materials: PA,PC, PS, and POM. According to material experts, this test is best used when resilience, or creep, is less likely to affect test results.
