Every single day, a new application of adhesive tapes has been discovered.

PSA- Pressure Sensitive Adhesive, is the primary type of glue to use for production of adhesive tapes, labels and more.

We meet these products every day, adhesive tapes and labels are located on smartphones, computers, vehicles, at home, and in our office. In the past few years, tapes and label could be seen even on clothes.

PSA could become adherent to many surfaces, as long as the surface is clean and dry, tapes and labels can be efficiently applying by the slight handy press.

Application of PSA may not require to activating the glue by water, organic solvents or heat. The bonding strength is influenced directly by applied pressing forces.

PSAs replace traditional fastening in every industry. More and more applications are created every moment, due to rapid improvement in adhesive technology, using efficiency, and low prices, in comparison to traditional fastening (screws, Nails, etc.)  or liquid adhesive.

What are the advantages of PAS tapes?

  • Thinner and lighter materials
  • Bonds dissimilar materials without incompatibility concerns
  • Provides vibration dampening and noise reduction
  • Reduces assembly time
  • Eliminates the need for surface refinishing
  • Eliminates visible mechanical fasteners for cosmetic superiority
  • Provides uniform thickness and gap filling properties

 

What kind of adhesives are used for PSA Tapes?

Rubber: Adhesives which are based on natural or synthetic rubbers and formulated with tackifying resins, oils, and anti-oxidants. Rubber is the most cost-effective PSA and offers quick stick capability. Rubber adhesive is not recommended for high heat applications.

Acrylic: Adhesives formulated with acrylic polymers and generally has a better long term aging and more resistance to solvents and environmental factors. Acrylic adhesives typically develop a stronger bond than the traditional Rubber adhesive and can take higher temperatures

Silicone: Formulated with Silicone polymers and the only glue that will bond well with silicon substrates. Silicone adhesives are relatively expensive and have a very low initial tack, but can withstand higher temperatures than both Rubber and Acrylic adhesive.

 

What is the Construction of a Typical Pressure Sensitive Adhesive Tape?

Single Coated- An adhesive coated on one side of a material. A silicone coated release liner protects the glue.

Transfer Tape- An unsupported mass of adhesive film coated on a release liner which has a release coat on both sides. Transfer tapes offer good conformability to irregular surfaces.

Double Coated- A carrier is coated on both sides with PSA. The adhesive carrier can be a wide variety of materials including plastic films, tissue, nonwovens, etc. Typical uses include laminates and carpet tape.

Self Wound- Tape’s carrier which is coated on one side with PSA and on the other with a release coating. There is no release liner with these types of products. Carton sealing, Duct, and Masking are all examples of self-wound tapes.
