Bio-based natural rubber compound and its use

摘要

The invention relates to a pressure-sensitive adhesive which is bio-based to at least 95% by weight, preferably 98% by weight, comprising natural rubber as base polymer and adhesive resins of bio-based raw materials, the proportion of tackifier resins being 80 to 120 phr, and at least one bio-based in the base polymer or the adhesive resins insoluble and not with the base polymer or the adhesive resins crosslinking microparticulate additive in the form of particles having a bulk density of at least 200 g / l and wherein at least 65% of the particles have a particle diameter of less than 32 microns, wherein the proportion of the additive based on the total pressure-sensitive adhesive between greater than 0 wt .-% and up to 20 wt .-% is.
