Pressure Sensitive Adhesives (PSA’s)Gaskets, seals, and pads are often manufactured with pressure sensitive adhesives as an assembly aid. We have over 40 years of experience working with PSA’s and can apply them to almost any material you may need. We are one of very few converters that can apply silicone or acrylic adhesives to silicone solid, sponge, or foam to meet your high temperature requirements. We stock a variety of different acrylic, silicone, and rubber PSA’s, and within each adhesive type we carry many different liners and also carry PSA’s with and without carriers to give us the flexibility to address any application and turn around your order quickly. Also, we are an authorized converter of 3M adhesives and we work with several other adhesive manufacturers to ensure access to whatever our customers need. Please contact us with any application you have and allow us to help you create an effective solution. Silicone PSA’s - Silicone based adhesives are the most expensive adhesive and generally are used for their temperature resistance. They have low initial tack strength that builds over time and can withstand continuous temperatures of 400°F and intermittent temperatures of 500°F. Silicone PSA’s have a maximum shelf life of 6 months. Acrylic PSA’s - Acrylic adhesives are the most commonly used PSA because they are the most versatile and have very good overall properties. They are compounded in many different ways to allow adhesion to rough surfaces, porous surfaces, powder coated and other low surface energy surfaces, and many others. They are most commonly used in thicknesses ranging from 0.002” to 0.005”, but are available in thicknesses up to 0.020”. Acrylics have good chemical, UV, and shear resistance and can handle temperatures ranging from –40°F to 300°F. They have a maximum shelf life of about 2 years. Rubber PSA’s - Rubber based adhesives are generally the least expensive adhesive. They usually have high initial tack strength and about a 1 year maximum shelf life. These adhesives tend to harden (and lose adhesion) over time, especially when exposed to sunlight and weather. Electrically Conductive PSA - We have an electrically conductive PSA in stock for your EMI or ESD applications. The electrically conductive pressure sensitive adhesive that we stock is an acrylic and is used for EMI shielding and for ESD grounding of gaskets and pads. Thermally Conductive PSA - We stock a thermally conductive acrylic PSA from Saint Gobain, a world leader in ceramics technology. Thermally conductive adhesives are filled with ceramic particles to promote heat transfer from the heat-generating device to the heat sink. Ceramics tend to ‘kill’ the adhesion of PSA’s so it is very important to have the technology to engineer and compound these products accurately to ensure performance. Acrylic Foam Adhesives - We have several different acrylic foam adhesives in stock in thicknesses ranging from 0.015” to 0.062”. Acrylic foams are flexible, high-strength bonding materials for a variety of applications and can replace mechanical fasteners in many instances. We can die cut or slit these products into any size, shape, or width needed. Materials Flyer |
