Description

β-Phellandrene/ Dipentene Copolymer is a synthetic polymer derived from the terpene monomers β-phellandrene and dipentene (d-limonene). This specialized copolymer is valued for its unique resinous character, tackifying properties, and compatibility with a wide range of polymers and solvents. It serves as a key performance additive in industrial formulations requiring enhanced adhesion, flexibility, and hydrophobic characteristics. Primary demand comes from the adhesives, sealants, coatings, and rubber compounding industries.

Application

• Adhesive & Sealant Formulations: Acts as a tackifier and modifier to improve initial grab, peel strength, and flexibility in pressure-sensitive adhesives (PSAs), hot-melt adhesives, and construction sealants.
• Rubber Compounding: Used as a processing aid and softener to improve the dispersion of fillers, reduce viscosity during mixing, and enhance the elasticity of finished rubber products.
• Industrial Coatings & Inks: Imparts water resistance, gloss, and improved substrate wetting in protective coatings, printing inks, and overprint varnishes.
• Polymer Modification: Functions as a compatibilizer and plasticizing agent in blends of polar and non-polar polymers, improving overall material processability and performance.
• Caulks & Mastics: Enhances the body, non-sag properties, and adhesion of high-performance mastics and industrial caulking compounds.
• Foundry & Mold Making: Employed as a binder component in core and mold sands for metal casting, contributing to collapsibility and gas evolution control.
