Conventional PVB is used solely as safety‑protective glass, whereas SGP laminated glass can serve directly as a load‑bearing structural element. At the same thickness, its load‑carrying capacity is twice that of PVB, and under high winds or snow loads, its flexural deformation is only one quarter of that of PVB. Glass skywalks in scenic areas, glass stair treads, frameless glass flooring, and large‑spanning domes all rely on SGP to enable extensive, all‑glass load‑bearing designs.

Iterative advancements in domestic SGP new material technology

Iterative advancements in domestic SGP new material technology

In the early days, SGP relied on imports; in recent years, China has achieved breakthroughs in ion‑crosslinking formulations, reducing the cost of domestically produced SGP by more than 30% while delivering performance comparable to imported products. This has addressed the reliance on imported high‑end engineering materials, enabling widespread use in ultra‑tall building curtain walls, scenic‑area glass bridges, and explosion‑proof security applications, thereby promoting the domestic adoption and standardization of new structural laminated materials.

New material with low water absorption, moisture resistance, and hydrolysis resistance

New material with low water absorption, moisture resistance, and hydrolysis resistance

SGP ionomer exhibits extremely low water absorption and possesses the inherent hydrolysis resistance of a new‑generation material. In contrast, PVB laminates with exposed edges are highly prone to delamination and blistering when exposed to moisture; SGP glass, by contrast, can be left with its edges fully exposed without edge sealing, making it ideally suited for humid environments such as coastal regions, swimming pools, and open‑air canopies. This significantly reduces long‑term maintenance costs and addresses the common issue of aging in outdoor laminated glass.

A new, safe material with high residual strength after fracture

A new, safe material with high residual strength after fracture

After conventional PVB‑laminated glass shatters, the interlayer softens and collapses; in contrast, SGP ion‑based material retains its rigidity even when fractured, firmly holding the fragments in place without detachment and preventing the entire pane from collapsing or falling. When used for glass walkways and high‑altitude guardrails, this advanced material can continue to support human loads temporarily after breakage, effectively eliminating the risk of falling debris. Its residual structural strength far exceeds that of traditional laminates, meeting the highest safety standards for public spaces.
