THERMAL SPRAY TAPE OPTIONS

CHR® 2905-7R– has a wide variety of uses in the plasma thermal spray market and comes with a release liner. It is most widely used as a high temperature masking tape for plating or plasma spray coatings. 2905-7R is also used as a holding tape, as a wrap for coils and transformers, and for high temperature splicing. It is extremely stable allowing it to withstand temperatures up to 500°F. Other characteristics include excellent abrasion and edge tear resistance and exceptional flex strength.

CHR® 2915-7– performs as a light duty plasma or flame spray masking tape. It is a very versatile tape without a release liner. Applications range from general industry electrical maintenance to high-temperature slicing and wrapping. Some specific applications are over-wrap on motor rewinds, protective wrapping for wire and cables, and high temperature masking tape for welding stainless steel. 2915-7 is strong, abrasion, solvent, and temperature resistant, and thermally stable. It can be used in applications that require continuous temperatures of up to 500°F.

CHR® 2975-8R/CHR® 2975-8RK– is used in the plasma spray process—a method of applying thin coatings of metal or high temperature ceramics to a surface. The coating is sprayed at high pressure and extreme temperatures. The tape is applied adjacent to areas of parts, which are to be plasma sprayed. This tape protects these areas from both the grit blasting, which is used as a surface preparation, and from the actual plasma spray coating. The aerospace industry is the prime market for the use of plasma spray tapes. Specifically jet engine manufacturers, overhaul centers, major airline maintenance centers, Air Force Bases, and Naval Air Rework Facilities (NARF’S). This tape is designed to withstand both the punishing abrasion of grit blasting and the extreme temperatures/pressures associated with the plasma spray process. The adhesive is a high temperature silicone, which allows the product to withstand continuous temperatures up to 500°. This tape has excellent strength and flexibility, which allows for easy wrapping of complex shapes and minimizes wrinkling during the flexing of cables. 2975-8R has a yellow PVC release liner and 2975-8RK has a fluorosilicone release liner.

CHR® HV60-18R/CHR® HV60-26R– is pressure sensitive adhesive tape specifically designed to withstand the extreme operating conditions found in high velocity oxygen fueled (HVOF) thermal spray applications. Product performance has been validated in both liquid and gas fueled systems with a wide range of coating materials including metal, metal alloys, and carbides. This tape features high temperature resistance, exceptionally high abrasion resistance, functions as a thermal insulator, and is highly flexible and conformable. It leaves no adhesive residue when removed.

Tech Tip– Thermal spray tapes are an excellent choice for combining conformability with thermal and abrasion resistance while protecting adjacent surfaces from spray.

UHMW Tapes

UHMW tapes consist of an ultra high molecular weight polyethylene film coated with a pressure sensitive acrylic adhesive. They exhibit excellent abrasion resistance and a low coefficient of friction, making them an excellent bearing or wear surface. UHMW tapes are used anywhere you need a frictionless or nonstick surface such as guide rails to reduce noise levels in glass bottling plants or desk drawers to provide smooth, friction free drawer movement.

UHMW tapes are widely used for:

  • Chutes and hopper liners
  • Bottle and can conveying systems
  • Guide rails in glass bottling plants
  • Replace desk drawer bearings

Performance characteristics:

  • Excellent abrasion resistance and wear characteristics
  • Low coefficient of friction makes it very slick
  • Nonstick surface
  • Moderate temperature range (-40°F - 225°F)
  • Adhesive back makes it easy to apply
  • More economical that PTFE tapes

CHR® 2302-5R (5 mil)/CHR® 2302-10R (10 mil)/CHR® 2302-20R (20mil)– can be used to provide an abrasion resistant, anti-stick, anti-friction surface at temperatures up to 225°F. This tape is frequently used to line chutes and conveyors. The product is often applied to guide rails to reduce noise levels in glass bottling plants. It is also used to replace desk drawer bearings, and to provide silky smooth, friction free drawer movement. 2302 exhibits excellent abrasion resistance and low coefficient of friction, making it an excellent protection for surfaces or bearings that experience heavy wear. It is more economical than PTFE tapes. It is supplied with a blue poly-film inter-liner which protects the adhesive, facilitates die cutting, and peels off easily. Tapes come with a release liner.

Tech Tip– The high temperature, high tack acrylic adhesive adheres readily to most dry, clean surfaces—firmly anchoring the product in place.

PTFE Tapes

PTFE glass fabric tapes are used for heat sealing and roller wrap applications. Along with good heat resistance, they also possess excellent electrical, mechanical, and chemical properties. PTFE tapes are available with a silicone adhesive backing. Acrylic adhesive backing is available upon request.

Heat sealing– PTFE tapes serve as durable non-stick coverings in heat sealing applications. Packaging materials don't stick to surfaces covered with PTFE tape. The tapes resist high temperatures, and provide a satisfactory rate of heat transfer from the sealing unit to the sealing area on the package.

Roller wrapping– PTFE tapes are used as a non-stick covering to prevent a build-up of inks, resins, and other chemicals on various industrial rollers. The tape also serves as a means to preserve the roller surface itself from damage caused by the exposure to a vast array of potentially abusive materials. 
 

PTFE tapes are widely used for:

  • High temperature release surfaces
  • Heat sealing
  • Dryer can covering
  • Roller wrap tape in production

Performance characteristics:

  • Excellent electrical, mechanical, and chemical properties
  • Nonstick surface—low coefficient of friction makes it very slick
  • Extremely durable and abrasion resistant
  • High dielectric and tensile strength
  • High temperature range (-100°F - 500°F)
  • Adhesive backing makes it easy to apply
  • Removes cleanly/leaves no adhesive residue

PTFE TAPE OPTIONS

CHR® SG25-03/CHR® SG25-03R (3 mil), CHR® SG25-06/CHR® SG25-06R (6 mil)– is an excellent choice for a standard grade PTFE glass tape. It offers a great balance between a coat weight, fiberglass substrate, and price. The SG25 series tape is frequently used by the packaging industry as a release surface on heat sealing equipment. The combination of a non- stick PTFE coating, fiberglass, and high temperature silicone adhesive allows SG25 to perform in continuous temperatures up to 500°F making it very versatile. It is dimensionally stable and will not “cold flow” under heavy loads. SG25 is available with or without a liner.

CHR® Premium SG05-06– offers an extra-heavy coating of PTFE resin resulting in a super-smooth, glass like finish. The SG05-06 series tape is frequently used by customers who require the same performance characteristics of a SG25 series (non- stick PTFE coating, fiberglass, dimensional stability and high temperature silicone adhesive allowing the tape to perform in continuous temperatures up to 500°) but have additional requirements of an extremely smooth, almost texture free glass like surface and a need for the tape to be more durable than a standard grade. 
The SG05-06 series tape is used by the packaging industry as a specialized heat sealing release surface on heat sealing equipment that will leave little or no impression on the product being sealed. It is also used as a premium release surface for PVC welding, baking/food industries, and is suitable for laminate separator sheets.

CHR® CHEMLAM® Copper SGC6-06– features multiple cast PTFE films that are laminated to a fiberglass substrate and then coated with a high temperature silicone adhesive on one side. The laminate construction provides an additional 0.001” (1 mil) of PTFE over the entire surface of the cloth. The copper colored film contains modified PTFE dispersion that results in a hardened surface. The combination of a uniform, pin-hole-free and hardened film results in an extremely durable product with extended lifetimes when compared to conventionally coated PTFE fabric tapes and enables CHEMLAM® Copper tapes to outperform thicker, higher grade PTFE coated fiberglass tapes at similar prices. CHEMLAM® Copper SGC6-06 is a superior release surface in industrial environments such as PVC welding, platen covers, heat sealing, and dry can covers. It is available with or without a liner.

Tech Tip– PTFE tapes help keep plastic films from sticking to hot metal bars and plates primarily used in food packaging.
