Polyester Polyol In Adhesive Production Process

Polyetser polyol mainly play the following roles in the adhesive production process:

1. Base Resin (main component)

As the main component of polyurethane adhesive, it gives adhesive good adhesion, flexibility and chemical resistance.

Affects the curing performance, mechanical strength and weather resistance of adhesive.

2. Toughener

Improve the flexibility and impact resistance of adhesive and prevent the brittle cracking of the bonding layer.

Applicable to high-strength structural adhesives and elastic adhesives, such as shoe glue, woodworking glue, etc.

3. Weathering Enhancer

Improve the UV resistance and chemical corrosion resistance of adhesive, suitable for outdoor or high-performance applications.

Adhesive used in the automotive, construction and aviation industries.

4. Rheology Regulator

Adjust the viscosity, fluidity and construction performance of adhesive to facilitate coating or spraying.

The opening time (operation time) of the adhesive can be adjusted to meet different process requirements.

5. Solvent Resistance Enhancer

Gives adhesive stronger solvent and oil resistance, suitable for high-demand industrial adhesive (such as aviation, electronics and automotive manufacturing).

Characteristics of Polyester Polyol

1. High Mechanical Strength: The polyurethane material produced has good wear resistance and strength.
2. Good Chemical Resistance: Excellent resistance to solvents, oils, acids and alkalis.
3. Average hydrolysis Resistance: Compared with polyether polyols, polyester polyol has slightly poor hydrolysis resistance.
4. Higher Glass Transition Temperature: It is used for rigid and elastomer applications.
5. Excellent Weather Resistance: Suitable for outdoor and high-performance polyurethane products.
