  • Device for measuring rubber wear
    Patent number: 11067489
    Abstract: The present invention provides a device and method for testing wear and friction properties of different materials under various experimental conditions representative of real usage conditions. In general, the device according to the invention is based on contacting a sample with a rotating disk with intermittent contact, in “open cycle” conditions, where dynamic loads are applied to the sample for the contact to occur. The control of dynamic loading is fully independent of the disk rotation.
    Type: Grant

  • Modified polyamide composition containing at least one phenolic compound
    Patent number: 8609785
    Abstract: The use of a phenolic compound for producing a modified polyamide having enhanced mechanical properties is described. A polyamide composition including at least such phenolic compound and optionally reinforcing or filler loads is also described. The composition is preferably a composition for molding, for example in the form of granules or powder, that can be used for the production of articles by injection-molding.
