Description

2-Propenoic Acid, Butyl Ester, Polymer With Chloroethene is a high-performance copolymer, commonly known as a vinyl chloride-butyl acrylate copolymer. This material is engineered to combine the durability and chemical resistance of polyvinyl chloride (PVC) with the flexibility and weatherability imparted by the butyl acrylate component. It is a critical raw material for manufacturers seeking to produce specialized, high-quality polymer compounds. Key industries that utilize this copolymer include plastics compounding, wire and cable insulation, and the formulation of specialty coatings and adhesives.

Application

• Wire and Cable Insulation & Sheathing: Imparts excellent flexibility, electrical properties, and resistance to environmental stress cracking.
• Plasticized PVC (Flexible PVC) Compounds: Acts as a permanent polymeric modifier to enhance low-temperature flexibility and processability.
• Specialty Coatings and Paints: Used in formulations requiring improved adhesion, durability, and resistance to chemicals and weathering.
• Adhesives and Sealants: Provides strong binding characteristics and flexibility in pressure-sensitive and construction adhesive applications.
• Polymer Modification: Serves as an impact modifier and processing aid for rigid PVC and other polymer blends.
• Automotive and Construction Profiles: Used in gaskets, seals, and trim where flexibility and long-term performance are required.
