Is contralube compatible with the materials in my component?
Compatibility issues are usually related to the base oil of the lubricant. The table below gives a rough insight into the compatibility of contralube770 with some of the more common plastics and elastomers. However, due to the variability of plastics and elastomer, it is advisable to perform a compatibility test. Submerge the material in the lubricant for more than two hours at 100°C. A lubricant-free control sample of each material should also be subjected to the same temperature at the same time. Material measurements – notably weight, dimensions, shore hardness and tensile strength – should be made before and after the test. Lubricant incompatibility can cause materials to swell, shrink, harden, soften, become more or less brittle, change colour etc. Dimensional changes of up to 5% are usually considered acceptable. The compatibility table below gives a rough guide to the compatiblity of contralube770 with various plastics and elastomers. There are numberous types & combinations hen
