Durometer is one of several measures of the hardness of a material. Hardness may be defined as a material's resistance to permanent indentation. The durometer scale was defined by Albert Ferdinand Shore, who developed a device to measure Shore hardness in the 1920s. The term durometer is often used to refer to tenpedia90A 95A 300mm 500mm Elastomer Pu Rod,the English name of Elastomer PU ROD ,commonly known as rubber,We are one of the leading companies which are extensively engaged in the manufacture and supply of a much wider comprehension of supreme quality Elastomer PU Rod .Reference: wwwlastic/pu-rod/36423771Was this helpful?
Durometer Shore Hardness Scale - Smooth-On, Inc.
For example a material with a Shore hardness of 95A is also a Shore 45D. The Shore 00 Hardness Scale measures rubbers and gels that are very soft. The Shore A Hardness Scale measures the hardness of flexible mold rubbers that range in hardness from very soft and flexible, to medium and somewhat flexible, to hard with almost no flexibility at all. Semi-rigid plastics can also be measured on
Hardness - O-ring
INDUSTRIES. The hardness of an elastomer is measured based on the depth of indentation by a standard size and shape impacting gauge. The hardness is obtained by comparing the difference between a small initial force and a much larger final force. The International Rubber Hardness Degrees (IRHD) scale has a range of 0 to 100,..
Durometer Hardness | Pleiger Polyurethane Hardness Chart
Durometer is the measure of hardness of an elastomer, similar to Rockewell hardness for steel. Durometer is a measure of indentation of a shaped pin into the elastomer surface at a given load. Shore A, D and 00 are the most commonly used scales; however, other scales such as B, C, and O are occasionally used.

Welcome to our Rubber Durometer Scale Section. Generally, most rubber materials fall under the rubber durometer scale of Shore A. Thus, if you need a rubber or O-ring durometer that feels like a running shoe sole, review our rubber hardness chart below, then pick Shore 70A. A rubber durometer of Shore 70A is the most commonly chosen material hardness for all applications.[PDF]

HARDNESS . Most urethane products range in hardness, between 54a and 75d, on the durometer scale. The “D” scale is used to measure hardness greater than 95A. NOTE: Redco Polyurethane bridges the gap between the rubbers and the stiffer structural plastics.[PDF]

Modulus where the durometer measurement is very sensitive at low hardness and is almost independent of Modulus at higher hardness. This can be shown by graphing Durometer vs. Modulus and W20% vs. modulus curves, as in Figure 8 below. 0 20 40 60 80 100 120 140 160 0 1000 2000 3000 4000 5000 6000 7000 8000 9000 Young's Modulus (PSI) IRHD W (20%)
