  • Applications

    Di(2-octyl) phthalate (CAS 131-15-7) is primarily used as a plasticizer for PVC and other flexible polymers to improve softness and processability in applications such as building materials (electrical cables, vinyl flooring), coatings and inks for flexible films, adhesives and laminates, and elastomer or polymer blends to enhance plasticity and processing.
