Relative Material Cost Comparison
The comparisons shown are to be used as a guide only. They may be helpful for estimating material costs, but due to price fluctuations and market conditions, material prices change frequently.
Hardness of Rubber Durometer
The Durometer is the International Standard Instrument used to measure the hardness of rubber or rubber-like materials. Durometers measure hardness by the penetration of an indentor into the rubber sample. The calibrated reading is expressed in a number value. The hardness values are always expressed in terms of plus or minus (±) five points (example: 60±5 Durometer).
It is important to note that when testing hardness of a rubber sample, the material should not be less than ¼” thick (.250″).
|Durometer Type (Shore)||Applicable to these types of materials|
|Type A (Shore)||Soft rubber & plastics|
|Type D (Shore)||Type D (Shore)|
|Type 00 (Shore)||Sponge & foam|
