Applications & Use Cases
- ▸ Non-phthalate primary plasticizer for flexible PVC compounds in food-contact film, packaging, and medical tubing where phthalate-free formulation is required.
- ▸ Plasticizer and coalescing aid in PVDC and vinyl barrier coatings, lacquers, and printing inks to improve flexibility and film formation.
- ▸ Plasticizer for cellulose-based polymers (cellulose acetate, nitrocellulose) and PLA/biopolymer compounds to lower glass transition and improve processability.
- ▸ Plasticizer and film-former in cosmetic and personal-care products such as nail lacquers, hair sprays, and antiperspirants.
- ▸ Plasticizer for pharmaceutical and food-contact enteric/film coatings (non-pharma industrial supply only); commonly used to soften polymer films and reduce brittleness.
