ThermoFlex Plus Antique is a durable polyurethane based heat vinyl that is highly flexible. It has a soft hand and strong grip and if applied properly will outlast the life of the garment. The Antique colors offer a semi gloss appearance to the silver and gold. These colors cannot have layers adhered on top of them, although we have successfully layered these products on top of other colors. Please Note: ThermoFlex Plus will NOT adhere to nylon. Be advised that dye migration has occurred with low energy dyes in polyester and poly-blend fabrics.
