FilmStick™ is a special poly-adhered fiberglass manufactured by IPAC that is used in the manufacture of thin wheels (typically 1/32” thick).  Available with or without perforation, this unique product is used on the bottom of the wheel mold for two reasons, first to keep the fiberglass layer flat and second keep the abrasive from falling through.
