Ködispace 4SG
Originating from top-tier German Kömmerling craftsmanship, 4SG technology completely replaces traditional aluminum spacers with a "reactive thermoplastic sealant." Through chemical bonding, it integrates seamlessly with the glass, granting insulating glass units over 25 years of ultimate airtightness and structural stability. In addition to significantly improving energy efficiency, it drastically reduces after-sales maintenance costs.
[International Standards & Destructive Strength Verification]
● Passes EN 1279-6 high-humidity and high-temperature accelerated aging tests.
● Failure mode must achieve ≥90% cohesive failure, ensuring no delamination or gas leakage under extreme temperature differences, completely eliminating edge thermal bridges.

Core Advantages of 4SG
Comprehensively overcomes the flaws of traditional aluminum spacers, bringing revolutionary breakthroughs in thermal insulation, aesthetics, and design flexibility.
1. Extreme Low Dew Point
The dew point of TPS-4SG warm-edge insulating glass reaches -60°C, greatly reducing indoor condensation; whereas standard aluminum spacers only reach -40°C, significantly improving living comfort.
2. No Butyl Sealant Overflow
Traditional aluminum spacers often suffer from butyl sealant overflow when heated. The 4SG structure is stable with no overflow risk, keeping the edges clean and transparent for the long term.
3. Structural Design Versatility
4SG adopts fully automatic inline extrusion processing, perfectly adapting to various custom-shaped glass configurations, breaking through the physical limits of rigid aluminum spacers and unleashing design inspiration.
LiSEC Smart Factory & Core Processes
Taiwan's first fully automated smart glass processing plant, aligning with the world's highest craftsmanship standards.
Core Technology: LiTPA® Seamless "Welding" Process
The failure of traditional insulating glass often begins at the joints. Chinta Glass utilizes Austria's exclusive LiSEC technology to achieve perfect visual and structural seamlessness through precise joint shaping and reheating "cross-linking" sealing.
Automated welding eliminates human intervention, solving the traditional issues of "bulging" and "scarring" caused by trapped air bubbles or thermal expansion. The system presses accurately, achieving a lower U-value and a lifespan exceeding 25 years.
01. Smart Sorting & Matching
Breaks traditional manual scheduling; fully automatic system allocation significantly improves production efficiency and delivery accuracy.
02. Fast Gas Filling with Minimal Loss
Precise inline argon filling ensures every piece of glass meets international thermal insulation standards.
03. Inline Data Identification
Embeds a digital identity into every glass piece, making the quality history 100% traceable from production to delivery.
04. Seamless Mixed Batch Production
Easily handles diverse designs; accurately produces both large-sized and custom-shaped glass.
05. High-Efficiency Continuous Operation
Unmanned operation ensures high product consistency, completely rejecting manual processing errors and waste.
06. Precise Warm-Edge Application
Custom application process tailored for 4SG technology, perfectly matching to maximize energy efficiency and appearance.

4SG Thermoplastic Spacer — Cohesive Failure Concept Demonstration
💡 Concept & Safety Explanation: This animation simulates the failure mode of the 4SG reactive thermoplastic spacer under extreme pulling forces, which is a crucial safety standard highly valued in high-rise curtain wall glass.
Because 4SG forms a strong chemical bond with the glass, its Adhesion is far greater than the sealant's own Cohesion. When subjected to extreme forces, the spacer will inevitably tear from within (cohesive failure) and will never detach from the glass surface.
⚠️ The Fatal Difference in Structural Safety:
If standard "non-reactive" spacers are used, under extreme wind pressure or external pulling, they often peel off completely from the glass contact surface (adhesive failure). Applied to high-altitude curtain walls, this not only causes an instant loss of airtightness but also causes the outer glass to lose its tensile support and fall, posing a severe hazard! The cohesive failure characteristic guaranteed by 4SG is the ultimate defense for ensuring "long-term airtightness" and "absolute safety" of the building envelope.
