Halogen-free Flame-Retardant Additive Introduced for PC Film

CAI Performance Additives has introduced a halogen-free flame retardant for polycarbonate (PC) film or sheet. With the addition of ST-SR487, 0.25-mm-thick PC film can achieve UL 94 V-0 certification, according to CAI.

The safety of halogen-based flame-retardant (FR) materials has come under increased scrutiny from consumers and regulators. “Halogen-based FR solutions can contain bromine, iodine, even chlorine; all chemicals of concern nowadays,” said CAI CEO Richard Marshall. “I’m proud to say we are offering a safer alternative to our customers in ST-SR487, our first FR additive that is entirely halogen-free.”

The additive also provides resistance to yellowing and other forms of weathering as well as hydrolysis protection for water-contact end products.

Headquartered in Boston, CAI Performance Additives LLC operates facilities in Massachusetts and offers logistics across North America to customers processing virgin and recycled engineering thermoplastics.
