Rubber Adhesives:

Rubber adhesives used with tape is based on natural or synthetic rubbers and formulated with tackifying resins, oils and antioxidants. Rubber is the most cost effective PSA and offers quick stick capability. Rubber adhesive is not recommended for high heat applications.


Acrylic Adhesives:

Acrylic adhesives are formulated with acrylic polymers and generally have better long-term aging and are more resistant to solvents and environmental factors. Acrylic adhesives typically develop a stronger bond than the traditional rubber adhesives and are able to take higher temperatures.


Silicone Adhesives:

Silicone adhesives are formulated with Silicone polymers and are the only adhesive that will bond well with silicone substrates. Silicone adhesives are relatively expensive and have a very low initial tack, but can withstand higher temperatures than both rubber and acrylic adhesive.
