2022/01/10

Domestic R&D in SGP materials has entered a new phase of refinement and functionalization, with three innovative products now being rolled out. First, an ultra-thin 0.38 mm optical SGP has achieved stable mass production, breaking the overseas monopoly on such thin‑specification products; it is primarily used in front windshields for autonomous driving and smart dimming glass, with haze levels below 0.5% to meet the stringent optical precision requirements of automotive applications. Second, an integrated electromagnetic shielding and fire‑resistant SGP has been commercialized, combining E60‑class fire resistance with electromagnetic shielding performance; it is already being deployed in large volumes for government‑classified buildings and military‑grade security glass projects. Third, a bio‑based, environmentally friendly SGP has entered the pilot‑scale stage; leading material companies are leveraging renewable monomers to modify ion‑based formulations, and a recyclable SGP variant is expected to begin small‑batch production by 2027, aligning with the industry’s broader carbon‑neutral development trend. Meanwhile, industry testing standards have been upgraded, with the implementation of an AI‑driven, all‑dimensional weathering and peel‑strength verification system that addresses at the source the risks of long‑term delamination and aging in SGP laminated glass, thereby driving a comprehensive upgrade in product quality across the sector.

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.
