Which test is performed for rubber?

Rubber and elastomers are tested using various tension, compression, and adhesion tests. These tests are similar to those performed on other materials, but the key difference is in the control of the environment.

What is ML in rubber?

The rheometric curve is an imprint of the vulcanizing and processing properties of rubber compounds. As the compound heats up, its viscosity drops, which is reflected in a decreased torque (resistance) on the rotor. The lowest value of the torque curve, expressed in dN*m, is called ML (Moment Lowest).

How do you test rubber material?

Mechanical Testing of Rubber Tensile Properties (ASTM D412) and Durometer A Hardness (ASTM D2240) provide a good baseline measurement of the properties of a rubber. These two properties are the most common baseline measurements made on rubber samples. Durometer A Hardness (ASTM D2240) is also known as Shore hardness.

What is the test to measure the curing rate of rubber?

Rheometer
During rubber vulcanization, a Rheometer determines the plasticity, including the cure rate and examines the behavior of the rubber mixture of after it has been vulcanized.

Which is the best instrument for rubber testing?

The new rubber testing instruments include a Rubber Process Analyzer (RPA), Moving Die Rheometer (MDR), Mooney Viscometer, Automated Density Tester and Automated Hardness Tester.

Where can I find M & L testing equipment?

M&L Testing Equipment which has been serving the Canadian Construction and Consulting industries for 61 years is pleased to announce they have been appointed exclusive sales & service Rep in Eastern Canada for Applied Test Systems (ATS).

Who are the suppliers of materials testing equipment?

Since 1960, M&L Testing has been a leader in the supply, service and calibration of materials testing equipment for the asphalt, concrete, soils and steel testing industries. We have always taken pride in offering not only the supply but also servicing and calibration of everything as well.

How many ASTM methods are used to test rubber?

There are currently over 140 ASTM Standard Methods that are actively used to test these raw materials used in the rubber industry. The mixing process also is a very large source of variation in the factory. There are another 25 ASTM methods that are used to test the quality of mixed batches.
