New generation TPS Insulating Glass Introduction
Due to its superior energy-saving performance, insulating glass has been used more and more widely in buildings. At the same time, with the gradual improvement of building energy-saving standards and the promotion and application of passive buildings, the requirements for the energy-saving characteristics of insulating glass are gradually increasing. Low-E glass is widely used, and the insulating glass is filled with inert gases such as argon and krypton,more and more warm edge spacer is used to replace traditional aluminium spacer. In previous posts,we introduced the function of Argon and warm edge spacer in double glass units. How argon content affect double glass unit performance Argon filled insulating glass VS warm edge spacer insulating glass Here we introduce new generation TPS insulating glass.
What’s TPS insulating glass?
TPS is short for THERMO PLASTICS PACER. TPS is a new type of insulating glass warm-edge system, which uses special butyl rubber as auxiliary material and is filled with thermoplastic spacers of desiccant which Can perfectly replace traditional aluminum spacers. TPS is not a new technology. It was first invented and put into commercial application by the German Kommerling Group. The first insulating glass using TPS technology was born in 1974, Dalian Huaying introduced China's first TPS insulating glass production line in 2010, realizing the integration of China's insulating glass warm edge technology with the world.
TPS IGU structure
Features of TPS insulating glass
(1) TPS thermoplastic spacers do not contain metal inserts, which improves the thermal barrier of the glass edge; (2) Have a more even surface temperature distribution on the inner and outer glass surfaces effectively reducing condensation; (3) Elastic edge sealing makes the glass design more flexible and convenient, which guarantee the IGU quality and stability. (4) Automatic production,High quality control, longer life; (5) The secondary sealant can be silicone or polysulfide sealant. Let analysis the TPS insulating glass,why it’s new generation?
shaped insulated glass production with TPS - Excellent thermal conductivity. The edge sealing materials of insulating glass include aluminum spacer, steel and stainless steel materials, organic silicon materials, etc. Due to the different thermal conductivity of the materials, the heat conduction formed at glass edge is also very different. Below table shows shows the thermal conductivity of different types of materials used in insulating glass. Thermoplastic spacers (TPS) abandon the aluminum, stainless steel and other metals with good heat transfer,The linear thermal conductivity of insulating glass made of TPS is much lower than that of traditional products, which prevents heat loss at glass edge. Thereby improving the energy-saving effect of the whole window.
Windows U value calculation TPS has better heat barrier properties than aluminum IGU. It can significantly increase the air temperature near the window and reduce the indoor temperature difference. It also has stable indoor climate, lower air convection, a more comfortable indoor environment, and reduces condensation on the edge of the glass.,reducing the maintenance cost of the window frame.
Indoor and glass surface temperature compare - Low Vapor &Air transmission rate TPS are directly extruded with special butyl rubber mixed desiccant, and the consistency of the sealing material is good. At the same time, because the TPS can also form an intimate chemical bond with secondary silicon sealant, the IGU structure is more stable with higher bonding strength. Table 2 shows the water vapor and gas permeability of different sealing materials. It can be seen that butyl rubber have better water vapor and gas barrier properties than silicone and polysulfide . According to the GB11944-2012 test, TPS IGU system has the lowest argon leakage rate,the test kept 5 cycles * 77days test and result is below,argon content decreased by around 4% after 5 cycles weather simulation,lifetime is much better than current other insulating glass systems. - Automatic glass production. TPS insulating glass system is produced by fully automatic machines. From glass handle and loading, the removal of the glass edge coating, the cleaning and drying, the placing of the thermoplastic strip, the argon filling,and glass bonding, and secondary sealant are produced by an automated system. Avoiding errors and inconsistencies that may be caused by manual operation, achieving a high degree of uniformity of corner sealing, completely eliminating the poor corner sealing of traditional aluminum insulating glass, and suitable for producing TPS IGU any type and size. 4.Perfect sealing performance,acoustic performance The good mechanical properties and peel strength of TPS ensure the edge sealing performance under positive and negative pressure. The elasticity of TPS thermoplastic spacers ensures that it can be applied to frequent changes in external temperature and wind pressure, and has good anti-resonance and sound insulation properties.
Aluminium spacer IGU will lose sealing effect under imbalance air pressure
TPS stripe is suitable for frequently changed temperature and pressure TPS can not only maintain the IGU sealing performance, it can also withstand long-term strong squeezing without losing the sealing performance. Thermoplastic spacers (TPS) is a new generation of insulating glass edge sealing materials. This insulating glass system can increase the sealing life of insulating glass and improve the edge effect of insulating glass. It should be promoted vigorously. However, at present, both the materials and fully automatic production equipment need imported, and the price is one of the main reasons restricting the promotion and application of TPS insulating glass.
TPS insulated glass production line-Bystronic In China,there’re several TPS insulating glass manufacturers,such as Dalian Huaying,Linyi CNG,Baoding Dahan glass etc.With the increased requirement of passive houses and stricter energy saving demand, TPS will finally replace traditional aluminium ones,it will become the final element that can be upgraded in IGU system.
