Category:BARRIER-STRIP FOAM TECHNIQUE

Product specifications:

Details

A. Foaming technique may reduce energy consumption resulted from air circulation of barrier-strip heat insulation molding. Non-foamed K-value is 2.3 to 3.5, and the K-value of foamed profile can be lowered to 1.5 to 2.

B. Preventing siphonage effect: PA66GF25 heat insulating strip has certain water absorption. In winter, steam generated from air circulation inside profile cavity is absorbed by heat insulating strip, and brittle rupture will occur when coefficient of linear expansion reaches 30%. This will not happen to the profile after foaming, and PU foaming absorbs no water.

1、Stopping convection phenomenon in barrier-strip cavity, and improving heat-insulating performance of doors and windows.

Foaming technique may reduce energy consumption resulted from air circulation of barrier-strip heat insulation molding. Non-foamed K-value is 2.3 to 3.5, and the K-value of foamed profile can be lowered to 1.5 to 2.

2、 Preventing siphonage effect and seepage phenomenon resulted from the physical connection part between heat-insulating strip and metal.

PA66GF25 heat insulating strip has certain water absorption. In winter, steam generated from air circulation inside profile cavity is absorbed by heat insulating strip, and brittle rupture will occur when coefficient of linear expansion reaches 30%. This will not happen to the profile after foaming, and PU foaming absorbs no water.

3、Preventing shrinkage of heat-insulating strip that will break away from connection due to freeze expansion after hydrops inside thermal-insulation cavity.

 

4、Help to improve profile’s integral rigidity.

Effectively making up for the insufficient press-in in profile’s insertion process that leads to defective goods.
