Hydrocarbon Polyterpene Adhesives & Sealants: These are the primary applications, where polyterpenes are used as tackifiers in: Pressure-Sensitive Adhesives (PSAs): High-performance adhesives for tapes, labels, and specialty films. Hot-Melt Adhesives (HMAs): Used in packaging, carton closing, bookbinding, diapers, and sanitary products. Solvent-Based Adhesives: Used in rubber cements and friction tapes. Sealants & Mastics: Including tire puncture sealants. Rubber & Tire Industry: Polyterpenes act as tackifying agents in rubber compounding (natural rubber, SBR, neoprene, EVA), increasing bond strength and heat resistance. Paints, Coatings, and Inks: They improve adhesion, flexibility, and gloss, particularly in printing inks and specialty coatings. Food & Medical Applications: Due to their non-toxic nature, they are used in: Chewing Gum Base: Providing masticatory elasticity. Food Packaging: In films intended for indirect food contact. Medical Rubber Goods: Including medical-grade adhesive tapes. Paper Sizing: Used in the paper industry to improve moisture barrier properties and resistance to wetting.
