1: Acrylic emulsion pressure sensitive adhesive Compared with acrylic solvent pressure sensitive adhesive, the pressure sensitive adhesive has poor water resistance, moisture resistance and heat resistance, so it is important to improve these properties, otherwise it is difficult to replace the solvent pressure sensitive adhesive.
2: Solvent-based pressure-sensitive adhesives are used in the production of medium and high-grade products in the field of functional pressure-sensitive adhesives such as industrial insulating adhesive tapes due to various production performances.
3: Hot melt pressure sensitive adhesive is the development direction of future pressure sensitive adhesive, and rubber type pressure sensitive adhesive has no major technological progress in recent years.
4: Non-water-dispersible pressure-sensitive adhesive is used to prepare pressure-sensitive adhesives with special properties, such as pressure-sensitive adhesives with good embossability.
5: Curing pressure sensitive adhesive
The pressure-sensitive adhesive is pressure-sensitive adhesive when it contacts the surface. After a period of time, it is cured by heat, anaerobic curing, crosslinking agent solution, photo-cation hardening, UV reaction, etc. to improve the cohesive force and obtain the strength of the adhesive. However, it is necessary to solve the problem of long curing time and storage stability.
6: medical pressure sensitive adhesive
Cross-linked polyurethane pressure sensitive adhesive has no odor, small skin irritation, low adhesion, easy peeling, biodegradability, suitable for making cream, percutaneous absorption belt, long-term bandage, etc., styrene rubber, etc. The pressure-sensitive adhesive tape has good sweat absorption, adhesiveness and peeling property, polyethylene rubber pressure-sensitive adhesive tape is used for temporarily fixing medical tape, silicone pressure sensitive adhesive is used for drug delivery, and surgical medical treatment is also possible in high-humidity environment. Water resistant pressure sensitive adhesive for clothing, sterilizing pressure sensitive film, etc.
8: Intelligent pressure sensitive adhesive is used in semiconductor, electronic component processing, ceramic capacitors, medical adhesives, etc.
9: Special pressure sensitive products
Conductive adhesive tape, thermal pressure sensitive film, flame retardant adhesive tape, wet adhesive tape, luminous adhesive tape and other pressure sensitive adhesive products are being developed and researched.
In the development stage of pressure sensitive adhesive production, in addition to saving resources, energy saving, reasonable process, and ensuring product quality, more attention is paid to environmental protection issues of pressure sensitive adhesive products, such as recycling of waste after pressure sensitive adhesive products and disposal of waste.
