What is Poly(vinyl chloride-co-isobutyl vinyl ether)?
Poly(vinyl chloride-co-isobutyl vinyl ether) (CAS 25154-85-2), also known as vinyl chloride-vinyl isobutyl ether copolymer, is a thermoplastic resin produced by copolymerizing vinyl chloride with isobutyl vinyl ether.
Where is Poly(vinyl chloride-co-isobutyl vinyl ether) used?
- Coatings: improved film flexibility and adhesion
- Industrial protective and decorative finishes: adhesion to metals and plastics
- Printing inks: binder resin where controlled viscosity is critical
- Adhesives and sealants: cohesive strength with soft, conformable character
- Plastics compounding: rheological modification of PVC-based compounds, easing processing at lower temperatures
- It acts as an internal plasticizer, improving flexibility and processability without separate plasticizer additions.
Commercial specifications
- Grades differentiated by viscosity or K-value to match processing requirements
- Particle size and molecular weight vary by grade
- Packaging from 25 kg bags to bulk quantities
