The introduction to the role and product performance of each component in the Truspacer insulating glass sealing spacer
Truspacer insulating glass sealing spacer
Truspacer is a warm edge spacer system ideal for high-volume production of double and triple pane insulating glass, it is preassembled with butyl sealant, 3A molecular sieve, undulating aluminum spacer bar and heat insulation strip and so on, it can replace the traditional IG production mode and greatly improve production efficiency. The butyl sealant used is more effective than the raw materials of other manufacturers.
Butyl rubber, which has excellent air tightness, mainly plays a water vapor sealing role in the rubber strip, and is divided into two categories: high-quality butyl rubber and recycled butyl rubber. Among them, high-quality butyl rubber has excellent air tightness, good chemical resistance and corrosion resistance; Individual manufactures in order to reduce the cost will usually choose recycled butyl rubber, recycled butyl rubber is generally the tire inner tube recycling redone products, odor, poor sealing, poor formula stability, the price is 40% of high-quality butyl rubber, because it is recycled and redone products so the performance is not good, and the sealing performance can not be fully guaranteed.
The butyl sealant used in the Truspacer strip can effectively resist the penetration of water vapor into the hollow glass. The water vapor transmission speed of the butyl sealant is the lowest among all sealants such as silicone rubber, polysulfide rubber, and polyurethane rubber. Butyl sealant has the dual functions of physical bonding and chemical bonding, which can ensure the best bonding performance between the sealant and the glass. The adhesive force between the adhesive strip and the glass can reach and maintain the maximum value with the increase of time.
