Gelest’s Biosafe HM4100 provides permanent protection of polymers, coatings, thin films, laminates, polymeric beverage tubing, and filter media that come in contact with food and drinking water. Biosafe antimicrobial technology protects surfaces from staining, pitting, deterioration and odour caused by bacteria, mould, mildew and fungi. It does not compromise end-product safety by migrating out of the plastic or being rubbed off the surface.
The EPA label for the product lists it as an approved-use polymer and coating for food preparation surfaces and polymeric beverage tubing at a loading level up to one percent by weight. Toxicity tests have shown them to cause no irritation or sensitisation in skin contact, and it contains no volatile organic compounds, heavy metals, arsenic or polychlorinated phenols.
