The present invention relates to elastomeric compositions for tyres and relative compounds, components and tyres comprising them, said compositions comprising an elastomeric polymer, a phenolic product, optionally already partially cross-linked, optionally an aldehyde and/or at least a methylene donor product and an oxidised carbon allotrope as a cross-linking catalyst. Advantageously, this catalyst is able to complete the cross-linking reactions of the phenolic resins in the conventional tim...
The multifunctional composite material comprises a polymeric matrix filled with electrically conductive nanoparticles combined with a self-healing molecular filler selected in the group consisting of molecules and oligomers containing groups acting as donors and acceptors of hydrogen bonds.
A method for measuring the quantity of super absorbent polymers (SAP) in a sample derived from absorbent sanitary products comprising at least one portion of a portion of cellulose and/or a portion of plastic in addition to a portion of SAP. The SAP contained in the sample comprise polymers of linear polyacrylate (LPA) and/or polymers of cross-linked polyacrylate (CLP A), the method comprises the steps of: a) placing a first aliquot of the sample in an aqueous solution comprising hydrogen per...
