Description

1-Butene, Polymer with 2-Butene and 2-Methyl-1-Propene, Ep. is a specialized polyolefin copolymer derived from a controlled polymerization of C4 olefins. This engineered material is valued for its unique balance of flexibility, chemical resistance, and processability, making it a versatile intermediate for advanced polymer formulations. It is primarily sought by manufacturers in the adhesives, sealants, and polymer modification industries seeking to enhance product performance.

Application

• Polymer Modification: Acts as a key component or compatibilizer in polyolefin blends to improve impact strength, flexibility, and processability.
• Adhesive & Sealant Formulations: Used as a tackifier or base polymer in hot-melt and pressure-sensitive adhesives, providing excellent adhesion and cohesion.
• Elastomer Production: Serves as a co-monomer in the synthesis of specialty elastomers and thermoplastic vulcanizates (TPVs) for automotive and industrial parts.
• Lubricant & Oil Additives: Employed as a viscosity index improver or dispersant component in synthetic lubricants and industrial oils.
• Waxes and Coatings: Incorporated into synthetic waxes and protective coatings to enhance gloss, water resistance, and durability.
• Packaging Materials: Used in film and flexible packaging layers to improve seal integrity and mechanical properties.
