A high-tech company specializing in the production, manufacturing, and R&D of ionically charged interlayer films.
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.

Iterative advancements in domestic SGP new material technology
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.

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

A new, safe material with high residual strength after fracture
SGP exhibits excellent adhesion compatibility with metals.
SGP film exhibits high bonding strength with steel, aluminum, and stainless steel, and remains resistant to corrosion and delamination even under prolonged contact with structural adhesives and metal hardware. When used in frameless glass railings, point-supported curtain walls, and metal‑framed skylights, SGP laminated glass ensures that hardware joints are less prone to debonding and loosening, making it ideally suited for large‑area, minimalist glass façades without visible mullions.

Explosion-proof and impact-resistant applications
Multi-layer tempered glass with a thick SGP interlayer can be used to produce explosion‑proof, burglar‑resistant, and typhoon‑proof glazing. Its high‑strength adhesion withstands heavy impacts and blast waves, preventing shards from scattering or penetrating. It is ideal for high‑rise hurricane‑resistant exterior windows, bulletproof bank counters, explosion‑proof partitions in industrial facilities, and protective railings in scenic areas, delivering superior impact resistance that meets safety standards exceeding those of conventional laminated glass.

SGP can be used as structural load-bearing glass.
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.

Unique safety performance after SGP shattering
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.

The penetration rate of panoramic sunroofs in new-energy vehicles continues to rise, making it the fastest-growing segment for SGP interlayer film. According to industry research, by 2026, domestic demand for SGP‑laminated glass used in automotive sunroofs is expected to exceed 110 million square meters, up 46.7% year over year. High‑end models such as Xiaomi’s SU7 Ultra, Zeekr 009, and Tesla’s Cybertruck are now standard‑equipped with SGP‑laminated sunroof glass, driving large‑scale validation of high‑optical‑grade, IR‑blocking composite SGP products. Leading glass manufacturers like Fuyao and Xinyi are steadily increasing their procurement of domestically produced SGP, gradually replacing costly imported materials. Meanwhile, modified SGP variants featuring heat‑insulating and low‑emissivity properties have entered pre‑installation testing with GAC Aion, with small‑batch deliveries projected to reach 2.8 million square meters this year. On the architectural side, demand is also strengthening: new versions of high‑rise building codes have been implemented across many regions, mandating the use of structural SGP laminated glass for ultra‑high‑rise curtain walls, skylights at high‑speed rail stations, and blast‑resistant glazing in coastal typhoon‑prone areas. By 2026, the overall domestic SGP market is forecast to reach RMB 5.98 billion, with the construction sector accounting for more than 62% of total usage.

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.
