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.

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.
