PRESSURE SENSITIVE ADHESIVES
Pressure Sensitive Adhesives (PSA’s) and foam tapes are used to attach to the surfaces of two substrates. When selecting a PSA or tape, not only must surface condition be considered: roughness, smoothness, porosity, cleanliness, flexibility, and surface energy, but also the environment: temperature range, chemical resistance, and UV light. Choosing the right adhesive for your demanding application can be challenging, but our knowledgeable engineering and sales staff are here to help you find the right solution.
There are many different types of PSA’s available with a wide range of physical properties. The most common types of pressure sensitive adhesives are Rubber, Acrylic, and Silicone.
Rubber Adhesives are normally a low cost option used for general purpose, short term, line-to-line applications. They usually have a good initial tack to many different substrates.
Acrylic adhesives provide resistance to solvents, UV light, elevated temperatures, plasticizers, and chemical reagents. They tend to be more costly than rubber-based varieties, but provide better long-term aging and environmental resistance. They have low to moderate initial tack and adhesion, but typically setup to a full bond within 24-48 hours. Acrylic adhesives generally do not adhere well to low-surface-energy substrates.
Silicone adhesives are by and large selected for the most demanding industrial applications because of their inherent resistance to temperature extremes, moisture, and chemicals. Silicone adhesives also offer excellent dielectric properties so that they are often used as pressure sensitive tapes for the electronics industry. Silicone PSA’s provide premium performance and are on average more expensive than all other types of pressure sensitive adhesives.
