Converting scrap tire rubber into a high performance polymer
P2GTR™ is a zero emission process described by the acronym PRIME (phase reactor integrated molecular electromagnetics) which facilitates a permutation, i.e. a complete change, of scrap ground tire rubber (GTR), 10 - 30 mesh feedstock into a functional, nano-composite. The PRIME Permutated (P2) GTR, subject to customer defined parameters, may be chemically grafted into a variety of resinous mediums to significantly enhance strength, flexibility and oxidation resistance.
Application Examples
In road applications, specific loadings of a cross linked and hybridized P2GTR show significant cost vs. benefit results as a modifier of performance graded asphalts. For example, a polymer loading of less than 4%, blended into an AC30 base yielded phase angle and DSR values sufficient to qualify the blend as a PG 76-22.
For roofing applications, combining a cross linked and chemically enhanced P2GTR, at a 12% loading, with a ca 500 pen, vacuum tower residuum, yielded a Class A, modified bitumen roofing membrane which passes all physical and weather related properties required under current UL, FMRC and UBC guidelines.
EARTH Resin - Epoxy Alloy Recycled Tire Heteropoly
EARTH Resin is a waterborne, latex adhesive manufactured in an emultion polymerization reactor - similar to today's finest liquid elastomeric polymers - with the revolutionary innovation that the entire lattice structure is grown by grafting onto a nano-sized, partially deconstructed, scrap tire "seed," i.e. PRIME permutated ground tire rubber(P2GTR). The tremendous benefit of these process advancement(s) is a material which exhibits the cured film, tenacity of the tire rubber, the bonding of epoxy, the flexibility of elastomers and the environmental efficiency of a latex. Depending upon the end use of the adhesive, the EARTH Resin is available in numerous grafted modalities for improved end of person.
