Chemical active product, not just as a filler
RJP™ and RJG™ have rough surfaces that facilitate the insertion in the compounds making this product highly compatible with the NR matrix compared to products deriving from traditional technologies.
The breaking load and tear strength improve if Powder/Granule from “H.P.W.J.” is incorporated into the NR matrix at levels up to 40 phr.
This proportion is higher than that relating to the granule resulting from traditional technologies which implies that the Powder/Granule obtained from H.P.W.J. has a greater activation of the surface due to rough surfaces and a favorable effect of devulcanization.
