Hardness is not a property of a compound family: it is set for each order to your specification.
The table shows typical purposes and properties. The compound for your part is chosen from your drawing and working conditions and confirmed in our offer.
Tailored specifications
Tailor-made for your needs
Every product we make is fully customisable: you choose the dimensions, the shape and the properties the part needs. These are the eight we tailor to your specification.
Wear and tear
Checked on the abrasion tester, which measures wear and tear.
Tear strength
Tear and crack resistance comes from the compound; the dynamometer measures breaking strength.
Hardness
Measured with Shore durometers and set for each order to your specification.
Chemical resistance
Our laboratory tests resistance to acids and other media.
Temperature resistance
Our laboratory tests resistance to temperature variations.
Ozone resistance
Chosen through the compound: ozone resistance is listed for CR and silicone.
Oil and grease resistance
Our laboratory tests resistance to oils; NBR is our oil- and fuel-resistant compound.
Elasticity
Measured on the dynamometer, together with breaking strength.
Values (hardness, temperature range, tolerances) are set for each order from your drawing and confirmed in our offer.
During production
Samples at every stage
Throughout production we continuously test samples to follow the process closely and keep quality consistent. A small press vulcanises selected samples — a key monitoring step that shows how the final products behave under different conditions. On a small roll mill we pull out the compound samples.
