Abstract

See full text

The present invention relates to an elastomeric polyurethane comprising at least a first flame retardant in an amount of ≥5% to ≤9% by weight based on the total weight of the elastomeric polyurethane and at least one mineral filler in an amount of ≥3% to ≤5% by weight based on the total weight of the elastomeric polyurethane, wherein the at least a first flame retardant is at least one phosphorous comprising polyol, wherein the at least one mineral filler is selected from the group consisting of carbonates, sulfates, silicates, mixtures and hydrated modifications thereof and wherein the total amount of the first flame retardant and the mineral filler is in the range of ≥10% to ≤14% by weight, based on the total weight of the elastomeric polyurethane, to a process for the preparation of said elastomeric polyurethane, to the use of these elastomeric polyurethane in offshore applications, mine and quarries applications, pulp and paper applications, shoe soles applications, handling applications, military application, transport application, railway and industrial rolls, industrials tires, electric encapsulation, wheels, rollers, doctor blades, hydro cyclones, sieves, sport tracks, insulating panels, acoustic insulations, wind blades or bumpers, and to offshore applications, mine and quarries applications, pulp and paper applications, shoe soles applications, handling applications, military application, transport application, railway and industrial rolls, industrials tires, electric encapsulation, wheels, rollers, doctor blades, hydro cyclones, sieves, sport tracks, insulating panels, acoustic insulations, wind blades or bumpers comprising such a polyurethane.
