Unique safety performance after SGP shattering

Release date:

2026/06/26

After ordinary PVB‑laminated glass shatters, the interlayer softens and the glass pane sags significantly, eventually detaching. In contrast, SGP‑laminated glass retains high rigidity upon breakage; the entire panel does not collapse, and the fragments remain firmly bonded to the interlayer, allowing it to temporarily support human loads. When used in frameless walkways or high‑rise curtain walls, it prevents the formation of through‑going voids after impact, substantially reducing the risk of falls from height and puncture injuries, while its residual structural strength far exceeds that of conventional laminated glass.

When ordinary PVB‑laminated glass shatters, the interlayer softens and the glass pane sags significantly, often detaching from the frame. In contrast, SGP‑laminated glass retains high rigidity upon breakage; the entire panel remains intact without collapsing, with fragments securely bonded to the interlayer, allowing it to temporarily support human loads. For frameless walkways and high‑rise curtain walls, this material is ideal: even after fracture, it does not develop through‑going voids, substantially reducing the risk of falls from height and puncture injuries, while its residual structural strength far exceeds that of conventional laminated glass.

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.
