Classification and use of pressure-sensitive adhesive：
In the field of new materials, there will always be a variety of look unfamiliar new term, although many of us are not quite understand the meaning of what it is, but a lot of material we often are exposed to, such as a pressure-sensitive adhesive, the use of pressure-sensitive adhesive great majority of recent years with the packaging, with horizontal, office supplies and expanding demand for a variety of labels, demand for pressure-sensitive people is also growing.
Pressure Sensitive Adhesive called the pressure-sensitive adhesives, also commonly known as stickers, referred to as pressure-sensitive adhesive. PSA product include pressure sensitive adhesive tapes and pressure-sensitive labels, pressure sensitive adhesive sheet three categories. They called the pressure-sensitive adhesive tape, pressure-sensitive adhesive labels, pressure-sensitive adhesive sheet, commonly known as tape, adhesive labels, pressure sensitive adhesive sheet. Adjusted such components in order to achieve products with better performance.
Pressure Sensitive Adhesive production of raw materials, due to the acrylic pressure-sensitive adhesive due to non-toxic, non-polluting, and has excellent resistance to aging, weather resistance, and pressure-sensitive adhesive property and become the development direction of the pressure-sensitive adhesive, and get widely used. Acrylic pressure-sensitive adhesive Appearance colorless and transparent and have good weather resistance; usually need tackifying resins, softeners and other antioxidant additives can get a good pressure sensitive adhesive properties, so the formula is simple; the use of copolymer and crosslinking can be prepared to meet a variety of pressure-sensitive adhesive to different performance requirements.
The pressure-sensitive adhesive agent for easy, it is not difficult to expose, stripping without prejudice, in a long time does not dry characteristics, select the primary acrylate monomer, while the second monomer, and the introduction of the a variety of functions monomers, through repeated experiments and reasonable adjustment formula, screened and synthesized polyol having a good overall performance of the total polyacrylate pressure sensitive adhesive emulsion coating process can be applied to require the transfer of double-sided tape trademark paper production. And acrylic pressure-sensitive adhesive tape, double-sided tape, protective tape, masking tape, medical tape and other tape and label not only in production, but also have a larger increase in the adhesive and coating properties for a variety of uses tape products are emerging. Nevertheless, the pressure-sensitive acrylic adhesive tape industry and is still the main general-purpose, single species, and adhesive properties, water resistance, heat resistance and moisture resistance, etc. can not meet the needs of the market, what still needs to import special tape. Such as high-strength double-sided tape, high temperature masking tape, fire retardant tape, magic tape and solar film and labeled tape.
