Oil sealing material (liquid) performance testing assessment

Rubber strap seals oil (liquid) performance, generally using standard test oil, according to test standard temperature conditions and the test time was immersed, through the comparison test values ​​before and after immersion (such as material hardness change, tensile strength change rate, Elongation change rate, volume change rate, compression, etc.), evaluation of its performance;
No1 Standard Oil is "low volume increased oil", a component of a mixture of mineral oil by solvent extraction, chemical treatment, dewaxed paraffinic residues and neutral oil;
No3 Standard Oil is a "high volume increased oil", by a selected naphthenic crude product obtained after vacuum distillation of two lubricating composition.
Different uses of the material is not the same evaluation index value.
