Asahi Sangyo Bitez Tape (BITEZ TAPE) Insulation Connecting Tape Sold in a set of 2 Used in air conditioning and HVAC construction for connecting insulation on refrigerant piping. Product Description (from the manufacturer's website) Connecting tape for pipe insulation covers (insulation material). Prevents gaps caused by heat shrinkage of air conditioning covered copper pipes, etc., and prevents condensation at the connection points. Applications: Connecting tape for pipe insulation covers (insulation material) such as air conditioning covered copper pipes. Purpose: To maintain the connection points of pipe insulation covers (insulation material) due to heat shrinkage. Materials: Surface layer / Colored aluminum foil polyethylene resin reinforced product (0.015mm), Insulation material / 30x expanded cross-linked polyolefin foam (1mm thick, conforming to JIS A9511 A-PE-C-1), Adhesive / Acrylic adhesive (with graduated release paper) How to use: ① Remove any dirt, dust, oil, moisture, etc. from the surface of the connection area. ② Adjust the insulation material joint surfaces and firmly butt them together without any gaps. ③ Wrap the pipe insulation cover (insulation material) so that the butted part is in the center of the 95mm wide Bitez tape. At that time, overlap with a 1/4 wrap around the outer circumference as a guide. ④ Rub (press) the tape wrapping area well by hand (until wrinkles appear on the entire surface of the colored aluminum foil) and make it adhere to the embossed surface irregularities. Precautions: ① Do not reapply. Forcibly peeling it off may cause breakage of the adhesive insulation material and a decrease in adhesion. ② From a safety and security perspective, we strongly recommend the combined use of adhesives and additional wrapping of various tapes depending on the usage environment. ● Operating conditions: Operating temperature environment: -10°C to 60°C
