Working closely together with clients, experts, institutions from laminated-glass industry for many years, we continuously update our silicone rubber bag according to the special requirements for glass gluing process. Our latest product adopt no splicing technology, which makes the thickness of the whole silicone rubber sheet more uniform, has better air tightness, higher tear strength and longer service life, and ensures the quality of glass products.
Oil resistance, aging resistance
Strong tear resistance,High resilience
High temperature and high pressure resistance
Non toxic, tasteless and environmental friendly

Vacuum silicone rubber bag for laminated glass is an important part of vacuum equipment for strengthening glass. The products are mainly used for vacuum creation of strengthening glass, sliding door glass and safety laminated glass. Vacuum principle is adopted to make the glass in the vacuum bag expel air without bubbles. Vacuum pressure (so there is no need for autoclave) is used to make the glass under pressure and melt the film at high temperature, so that the laminated materials (such as silk, paper, cloth, drawing paper, etc.) and the glass can be firmly bonded together to form a whole, so as to achieve the purpose of practical decoration, explosion-proof, safety and reliability
