2. The thermal conductivity of TPE is lower than that of aluminum spacer strips, reducing edge condensation and good thermal insulation performance.
3. No metal corrosion, suitable for coastal or high humidity environments.
4. It can be bent into complex shapes, suitable for special-shaped glass design, and is easy to process.
TPE Insulated Glass Common combination methods
Its common combination methods mainly involve glass type, spacer thickness, gas filling and other configurations
Combined by glass type
1. Double layer Insulated Glasses (most common):
① 5mmToughened Glass + 12mm TPE spacer + 5mmToughened Glass (such as: 5TPE12+5, suitable for ordinary energy-saving doors and windows)
② 6mm Low-E glass + 15mm TPE spacer bar + 6mm transparent glass (Low-E coating can improve thermal insulation performance, widen the spacer bar and enhance thermal insulation)
2. Third floor Insulated Glasses (high cold area)
① 4mm glass + 9mm TPE + 4mm glass + 9mm TPE + 4mm glass (such as: 4TPE9+4TPE9+4, better sound insulation and thermal insulation performance)
Combined by spacing bar thickness
① The width of the TPE spacer directly affects the thermal insulation performance of Insulated Glasses, common thicknesses: 9mm, 12mm, 15mm, 16mm, 20mm
② 12mm spacer bar: regular configuration, balancing cost and performance.
③ ≥15mm spacer bar: The effect is better when filled with inert gas (such as argon) and reduces thermal convection.
Combined by functional requirements
① Energy-saving type: Low-E glass + TPE spacer bar + Argon (reduce ultraviolet transmittance and reduce U value)
② Sound insulation type: laminated glass (outer layer) + TPE spacer strip + Insulated Glasses (inner layer) (such as: 6 laminated TPE12+6, used in airports and high-speed perimeters)
③ Safe type
④ Toughened Glass + TPE spacer + Toughened Glass (impact resistant, suitable for high-rise buildings)
Special combination
① Arc Insulated Glasses: The TPE spacer is bent and adapted to a special-shaped design.
② Built-in louvers Insulated Glasses: TPE seals the louvers to avoid dust entering.
Our factory TPE Insulated Glass processing and production specifications
1. Basic structural specifications: The thickness of single-layer glass is usually 5~19mm (common 5mm, 6mm, 8mm, 10mm, etc.). The thickness of hollow layer: 6mm, 9mm, 12mm, 15mm, 16mm, 20mm, etc. (selected according to sound insulation and heat insulation requirements).
Combination method:
Single cavity hollow: such as 5+12A+5 (two pieces of 5mm glass + 12mm hollow layer).
Double cavity hollow: such as 5+6A+5+6A+5 (three pieces of glass + two layers of hollow, better sound insulation).
It can be matched with Low-E glass, laminated glass, etc.
2. TPE (thermoplastic elastomer) replaces traditional aluminum strips or warm edge strips. Low thermal conductivity (reduces edge thermal bridge effect). Flexible structure, adapts to glass deformation and reduces stress cracking. No bending machine is required, and can be processed in any shape (such as curved glass). Width: Usually the same as the thickness of the hollow layer (such as the 12mm hollow layer corresponds to the 12mm wide TPE bar).
3. Special customization: The shape supports special shape (circular, triangle, etc.) and curved surface Insulated Glasses processing. It can be combined with Low-E coating, argon/krypton gas (enhanced heat insulation), dimmed glass, etc. The TPE spacer is available in black, gray, etc. to meet the aesthetic needs.
4. Performance standards
Airtightness: Comply with GB/T 11944-2012 (or EN 1279) standard, initial dew point ≤-40℃.
Condensation resistance: No condensation is present when the temperature difference of the hollow layer is ≥40℃.
Durability: Passed tests such as high temperature and high humidity, ultraviolet aging (lifetime ≥15 years).
Sound insulation performance: Weighted sound insulation volume (Rw) can reach 35~45dB (dual cavity structure is better).
Our factory TPE Insulated Glass key parameter selection
1) Selection of TPE sealing materials. Commonly used TPEs include SEBS (styrene-ethylene-butene-styrene copolymer), TPO (thermoplastic polyolefin), etc., and they need to be selected based on weather resistance, flexibility and adhesiveness. Hardness (Shaote A) is usually chosen from 40~80 Shore A. Too soft may lead to insufficient support, and too hard may affect the sealing effect. Weather resistance is tested through UV aging and high and low temperature cycles (-40℃~80℃) to ensure that it does not crack in long-term use.
2) For glass types, you can choose Toughened Glass (T), Low-E glass (relief heat insulation), colored glazed glass, etc. Glass thickness: 3-19mm is commonly used for single-layer glass.
3) The thickness of the spacer bar: generally 6~24mm, which affects the thermal insulation performance (U value). It is recommended to choose wider spacing strips (such as above 12mm) in cold areas.
4) Gas filling: Inert gases (such as argon and krypton) can reduce heat conduction, the filling concentration must be ≥90%, and ensure sealing to prevent leakage.
Hollow layer thickness: 9-15mm is a common sound insulation choice, and excessive thickness may reduce thermal insulation performance.
Our factory's TPE Insulated Glass processing process
1. Cutting: Cut the original glass sheet according to the customer's order size requirements, and perform edge treatment, and thoroughly clean the glass surface with deionized water or glass washing machine.
2. Cut the TPE strips according to the size of Insulated Glasses and make a closed frame (square, special shape, etc.) that matches the shape of the glass by hot bending or welding.
3. Desiccant injection: Fill the sub-sieve desiccant into the prefabricated cavity inside the TPE spacer strip and seal it.
4. Coat hot melt butyl glue on the contact surface of the TPE spacer with the glass.
5. Combination sheet: Precisely press two pieces (or more pieces) of glass with the TPE spacer strips, and after forming a hollow cavity, pressure is applied through a pressing roller or a press to ensure that the glue layer is evenly bonded, bubbles are discharged, and press-fit and shaped.
6. Inert gas filling: If the insulation performance is required, vacuum can be filled with inert gas such as argon (Ar), krypton gas (Kr), etc. to reduce the heat conduction of the hollow layer.
7. Coat naturally after coating polysulfide glue, silicone glue or polyurethane glue on the outer edges of the glass and TPE spacer strips.
8. Quality inspection, test airtightness, dew point and appearance, etc.
Our factory TPE Insulated Glass key process control points
1. Raw material control: Ensure that TPE materials meet standards (such as UV resistance, aging resistance, and low water vapor permeability). The glass substrate is dry, the surface is free of oil and dust, and the dryness is free. Select molecular sieve with high adsorption properties (such as type 3A) to ensure the moisture content is ≤0.5%.
2. Processing environment: Ambient temperature is 20~25℃, humidity is ≤30% RH (prevent TPE from moisture absorption or condensation on the glass surface).
3. The extrusion temperature of the TPE spacer is usually 160~200℃), dimensional accuracy: width tolerance ±0.1mm, ensuring matching with glass. Accurate bending angle (right angle ±0.5°), and no gaps in welded joints (visual inspection + airtightness test).
4. Quickly fill the desiccant (exposure time <30 minutes), and the filling amount must cover more than 80% of the spacer cavity.
5. Combination pressure: The pressing pressure is 0.5~0.7MPa to ensure that the TPE is closely fitted with the glass but does not deform.
6. Sealant coating: During double-channel sealing, the thickness of butyl glue coating is 0.3~0.5mm, and the curing time of polysulfide glue/silicon glue needs to be monitored.
7. Quality control and testing: The dew point of finished glass is ≤-40℃ (according to GB/T 11944 standard), and check whether water vapor remains in the hollow layer. According to airtightness test, the annual leakage rate after argon gas is <1%. There is no degumming or atomization after accelerating aging test (high temperature and high humidity, ultraviolet irradiation).

2. Energy-saving and environmentally friendly: TPE has a low thermal conductivity, which can significantly reduce the 'cold bridge effect' on the glass edge, improve overall thermal insulation performance, and reduce building energy consumption. The materials are recyclable and meet the requirements of green building.
3. Deformation resistance and weather resistance: TPE has a low shrinkage rate under temperature difference, avoiding seal failure due to thermal expansion and contraction, and is suitable for use in extreme climate areas.
