Polyurethane Glue And Plywood Glue | JCT Machinery

1. Viscosity Processing

Polyurethane sealant usually has a high viscosity, so vacuum planetary mixer and vacuum degassing equipment are required. Plywood glue has a relatively low viscosity and usually used a reactor.

2. Vacuum Degassing

Polyurethane glue requires vacuum degassing during production to remove bubbles and ensure the purity and performance of the colloid. Plywood glue generally does not require this process.

3. Temperature Control

The productionprecess of polyurethane glue requires high temperature control, and usually requires a heating and cooling system. The temperature control of plywood glue is relatively simple.

4. Reaction Characteristics

The production of polyurethane glue involves complex chemical reactions, which require the use of special reactors and precise reaction condition control. The production of plywood glue is relatively simple, mainly mixing and emulsification.
