The Nine Rubber Tests We Run Next to the Line
Hardness, density, ozone, ageing, tensile, elongation, resistivity, oil resistance and Mooney viscosity — what each one actually catches.
Where the testing happens
In our Beijing facility, right next to the production line, we have the equipment to test for Shore A hardness, density, ozone, ageing, tensile strength, elongation to fracture, vulcanization and insulation resistivity, oil resistance and Mooney viscosity.
What each one is really checking
Hardness and density catch a mis-weighed batch. Mooney viscosity catches a compound that will not flow the same way tomorrow. Tensile and elongation catch under-cure. Ozone and ageing catch a compound that is fine today and cracked in two years. Oil resistance catches EPDM specified where NBR was needed.
Why next to the line matters
A test in a laboratory a week away tells you what went wrong. A test beside the press tells the operator to stop. That is the whole argument for keeping the equipment in the building.
When an outside laboratory is used
For work that needs certified results we co-operate with CTI (Centre Testing International Corporation), based in Shanghai.

A sport pad has a metal face; a rubber pad does not. That single difference drives tooling count, unit price and how the part is validated.

Service conditions, not price, should pick the compound. Here is how we narrow it down and what we test to prove the choice.

Still deciding?
Send the service conditions and the annual volume. Our designers will propose a compound and a construction rather than asking you to pick one.
