Name BIS-HEMA POLY(1,4-BUTANEDIOL)-14/PEG-2/PPG-3/IPDI COPOLYMER Description Bis-HEMA Poly(1,4-Butanediol)-14/PEG-2/PPG-3/IPDI Copolymer is a copolymer of poly(1,4-butanediol)-14, PEG-2, PPG-3 and Isophorone Diisocyanate (IPDI), end-capped with HEMA. Benefits BINDING Considerations • Ethoxylated Chemical This is an ethoxylated chemical, meaning it’s been created with ethylene oxide, traces of which, along with its carcinogenic byproduct, 1,4-dioxane, can remain in the product.
• Endocrine Disruption
