What is pressure sensitive adhesive?

Pressure sensitive adhesive (PSA) is a hot melt adhesive that maintains permanent viscosity at room temperature. It can be coated on the surface of the substrate after heating and melting, and still maintains a certain viscosity after cooling. It can achieve bonding under low pressure and can be repeatedly pasted and peeled.

Technical Advantages

Automated and precise control to improve production efficiency
Efficient mixing and uniform dispersion to ensure colloid quality
Precise temperature control systems to optimize colloid performance
Highly environmentally friendly design in line with international standards
Compatible with multiple applications to meet different market needs

Pressure Sensitive Adhesive Formula

Ingredients	Functions
Base polymer (such as SIS, SBS, SEBS, EVA)	Provides viscosity, elasticity and weather resistance
Tackifying resin (such as C5/C9 petroleum resin)	Increases initial adhesion and improves bonding strength
Softener/Plasticizer (such as liquid tackifying resin, mineral oil)	Reduces viscosity and improves fluidity
Antioixidant	Increases thermal stability and prevent oxidative degradation
Filler (such as calcium carbonate)	Reduce cost and adjust viscosity

Q: How to produce pressure sensitive adhesives of different qualities?

A: JCT provides you with high-quality equipments to ensure that you can produce high-quality pressure sensitive adhesives.

To obtain pressure sensitive adhesive with different performance characteristics, the formula of the pressure sensitive adhesive needs to be adjusted:

Selection of Tackifying Resin Types: C5 resin enhances initial adhesion, C9 resin improves peel strength, and rosin resin improves transparency.
Selection of Polymers: SIS provides better elasticity, SBS enhances aging resistance, and SEBS is suitable for higher-end applications.
Adjustment of Softener: Affects the flexibility, fluidity and low-temperature resistance of the colloid, and needs to be adjusted according to application requirements.
Addition of Antioxidants: Prevents thermal degradation and extends the service life of hot melt glue.
