Petro-Rez PTL Polymerized mixed petroleum streams Akrochem Tackifier >> Hydrocarbon resin Rubber - Elastomer (Chloroprene, Butyl …) ADHESIVE PETRO-REZ PTL is a low molecular weight, plasticizer/tackifier which is polymerized from mixed petroleum streams. One of the salient features of this resin is its stability; it exhibits excellent resistance to acids, alkalies, water and salts. PETRO-REZ PTL can be used to modify other resins and polymers in rubber compounding, various adhesive systems, and high solids ink vehicles. Low molecular weight, stable, plasticizer/tackifier which is polymerized from mixed petroleum streams. Used to modify other resins and polymers in rubber compounding and various adhesive systems. Exhibits very good resistance to acids, alkalies, water and salts.
