Vacuum suction resin is a kind of waterborne polyurethane adhesive, because it needs a vacuum suction machine to pump the vacuum suction plastic so it is called vacuum plastic suction adhesive.It is widely used in the physical parts of the vacuum blister thermal composite, such as PVC and other soft materials and density board, particleboard, wood vacuum blister molding, mainly used for wood doors, cabinets, speakers board, computer desk, car console vacuum blister molding.
In the process of heating and softening, the PVC film is close to the MDF after spraying glue. The air between the PVC film and MDF is extracted by vacuum, and the PVC film is tightly pasted on MDF by atmospheric pressure. This process is called vacuum blister.The biggest characteristic of this process is no need to spray paint or paint, is a paint-free process.In addition, he can also cover concave-convex groove, curved edge, hollow carved pieces, is the other process can not be compared.The adhesive used for vacuum blister is vacuum blister plastic.

Vacuum suction process of the performance requirements with good flow ductility, no pitting surface after the suction;High solid content, quick drying;The initial viscosity is good, in the groove, the edge of the special requirements of plastic absorption of the initial viscosity is good;Good thermal aging performance;The activation temperature is low, the activation temperature is within the range of 55-65 degrees, the temperature is too high, the PVC film is easy to perforate.
Now, do you understand?Waterborne polyurethane vacuum suction plastic has the characteristics of being friendly to the environment, maneuverability and excellent bonding performance, etc. It is a better choice in the vacuum suction plastic process at present.
