Carriers and facestocks are important components of double and single coated tapes. CCT’s double coated tapes are constructed with a pressure sensitive adhesive (PSA) on both sides of a carrier or support component. Our single coated tapes are coated with PSA on one side of the support component. Carriers and facestocks can be engineered with a variety of substrates including films and foams and the choice will depend on the PSA and the end use application. The choice of carrier or facestock helps determine the properties of the final product.
Film carriers used in PSA construction offer a variety of thickness, chemical resistance, barrier properties, tensile strength, elongation, and temperature resistance.
Polyester (PET) is a clear plastic film carrier that can be used with most types of adhesives. It offers high tensile strength, excellent environmental stability and provides good barrier properties to most migratory chemicals.
Polyurethane (PU) is a soft, conformable film. It does not contain any plasticizers that could migrate out of the film and cause allergic reactions or hardening of the film over time. PU is also resistant to water, UV rays, chemicals, bacteria and fungus, and offers good water vapor transmission.
Polyethylene (PE) features a smooth surface, with excellent tear strength. This flexible carrier provides superior moisture resistance and chemical and solvent resistance.
Polypropylene (PP) features higher temperature and better chemical resistance than polyethylene, while still having good conformability.
Foam Carriers provide cushioning, conformability, and water resistance. Some examples are:
Polyethylene (PE) is a lightweight, resilient, closed-cell material available in a wide range of densities and colors. PE foam offers superb flexibility, strength, and tear resistance, as well as resistance to water, chemicals, solvents and grease.
Ethylene Vinyl Acetate (EVA) is a closed cell foam that is soft and significantly more durable than PE foam with great recovery characteristics. EVA foam will also have greater tensile and elongation properties than PE foam. Features include, impact and vibration absorption, weather and chemical resistance, and acoustic and thermal insulation properties.
Nonwoven carriers are engineered fabrics bonded together by entangling synthetic fibers either mechanically, thermally, or chemically. Nonwoven carriers offer a range of specific features such as, resilience, stretch, conformability and strength, which vary based on the choice of fiber and bonding process.
