What are the main ingredients of pressure-sensitive adhesive

The main components of pressure-sensitive adhesive include the main material, tackifier, filler, and additive. The main material is the main component of pressure-sensitive adhesive, which can be divided into four categories: acrylate, rubber, resin, rubber, and resin combination.

Viscosifier can improve the bond strength and cohesion strength of pressure-sensitive adhesives, commonly used viscosities are natural rubber, synthetic rubber, synthetic resin, and wax. The filler can adjust the properties of the pressure-sensitive adhesive so that the pressure-sensitive adhesive has better adaptability. Additives can give pressure-sensitive adhesive better application properties, such as temperature resistance, water resistance, cold resistance, and adhesive stripping strength measurement.

For example, the pressure-sensitive adhesive with acrylic ester as the main material has excellent water resistance and thermal stability, and can be used in the production of tape, self-adhesive tape, and die-cut products; Rubber pressure-sensitive adhesive has excellent flexibility and absorption properties and can be used in the production of medical tape, dust-free paper, disposable medical supplies, etc. The pressure-sensitive adhesive with synthetic resin as raw material has good water and heat resistance and can be used in the production of industrial self-adhesive fixing plates, transparent tape, and other products.

The above information is for reference only, and the specific composition of different pressure-sensitive adhesives may vary depending on the manufacturer and application.
