Saint-Gobain CHR® M797 Polyester Film Backing Natural Rubber Adhesive Pressure Sensitive Tape
Categories:	Polymer; Adhesive; Tape; Thermoset; Rubber or Thermoset Elastomer (TSE)
Material Notes:	CHR® M-Series (1 Mil PET/Rubber adhesive) is manufactured from polyester film with rubber pressure-sensitive adhesive. Features/Benefits: M797 resists high temperatures of conformal coating operation, is silicone free, and creates a true masking line. The thermosetting rubber adhesive system offers excellent quick-stick properties and flag resistance, yet unwinds easily. The polyester backing resists damage from sharp edges. Polyester backings offer low-cost, effective holding for materials. Operating temperature is -18 to +163 °C, elongation % at break is 100, tensile strength is 44N/cm and dielectric strength is 5,000 volts. Applications: M797 offers economical methods to hold, insulate and/or protect various materials. Information provided by Saint Gobain Performance Products.
