Description

4,7-Methano-1H-Indene, 3A,4,7,7A-Tetrahydro-, Polymer With Ethenylbenzene, Ethenylmethylbenzene, 1H-Indene And (1-Methylethenyl)Benzene, Hydrogenated is a specialized hydrogenated hydrocarbon resin derived from a complex polymer blend. This product is valued for its excellent thermal stability, light color, and broad compatibility with various polymers and elastomers. It serves as a crucial performance additive in industries requiring high-quality tackifiers, modifiers, and processing aids, particularly in adhesive formulations and rubber compounding.

Application

• Hot-Melt and Pressure-Sensitive Adhesives (PSA): Acts as a primary tackifier, providing excellent adhesion, cohesion, and peel strength.
• Rubber Compounding: Used as a processing aid and reinforcing agent in tire manufacturing and industrial rubber goods.
• Sealants and Caulks: Imparts flexibility, adhesion, and durability to construction and automotive sealants.
• Polymer Modification: Enhances the compatibility and performance of blends in engineering plastics and thermoplastic elastomers (TPE).
• Inks and Coatings: Functions as a resin modifier to improve gloss, hardness, and pigment wetting.
• Chewing Gum Base: Serves as a non-toxic, inert masticatory substance in food-grade applications (subject to specific purity grades).
