Description

Poly(Vinyl Chloride-Co-Isobutyl Vinyl Ether) is a specialized copolymer that combines the rigidity and chemical resistance of polyvinyl chloride (PVC) with the flexibility and processability imparted by the isobutyl vinyl ether comonomer. This engineered material is valued for its ability to create more pliable and impact-resistant formulations compared to standard PVC homopolymers. It is primarily sought by manufacturers in the polymer modification, specialty coatings, and adhesive industries seeking to fine-tune the physical properties of their end products.

Application

• As a modifier for rigid PVC formulations to improve impact strength and low-temperature flexibility.
• In the production of specialty coatings and paints, where it enhances film-forming properties and adhesion.
• As a key component in adhesive and sealant systems, contributing to tack and elasticity.
• For the modification of printing inks and overprint varnishes to adjust rheology and surface finish.
• In the formulation of plasticized compounds for wire and cable insulation or flexible sheeting.
• As a compatibilizer or processing aid in polymer blends to enhance miscibility and extrusion characteristics.
