Shanghai Haiyouwei New Materials

What Shanghai Haiyouwei New Materials does

Shanghai Haiyouwei New Materials Co., Ltd. (stock code 688680 on the Shanghai Stock Exchange STAR Market) is a Chinese high-molecular polymer materials manufacturer founded in 2005 and headquartered in Shanghai Zhangjiang Hi-Tech Park. The company produces photovoltaic encapsulant films (EVA, POE, EPE, and specialty co-extruded films) for solar module assembly, with full-spectrum coverage of TOPCon, HJT, BC, perovskite and BIPV cell technologies. Its product portfolio extends into automotive applications through proprietary PDCLC intelligent color dimming film (marketed as 墨影瞬光, featuring 5ms switching, ≤2% haze, ≥95% shading, and 99.99% UV blocking) and POE-based AXPO lightweight eco-leather for vehicle interiors, plus PVE high-performance glass encapsulant film for automotive and architectural glazing. Specialty adhesive films for electronics, medical devices, low-altitude flight, and sports equipment round out the portfolio.

The company's core technology platform rests on high-molecular polymer materials science, with proprietary PDCLC raw materials, UV conversion agents cross-linked into macromolecular networks to eliminate fluorescent migration, and co-extrusion processes for multilayer encapsulant structures. It claims the world's first patent for anti-migration optical film technology and the world's first mass-produced automotive-grade dark PDCLC dimming film. R&D is anchored by 100+ professionals with annual investment exceeding RMB 100 million and 300+ cumulative global patent applications. National-level 'Little Giant' enterprise status was re-certified in 2025.

The business model is hardware sales to enterprise B2B customers via direct field sales, channel partnerships, and technology licensing arrangements. Photovoltaic encapsulants generate per-square-meter volume revenue across cell-technology tiers; automotive dimming films and eco-leather generate revenue through OEM design-wins and platform supply contracts; specialty films serve electronics, medical, and industrial bonding applications. The company operates six Chinese production bases (Shanghai, Taizhou, Shangrao, Pinghu, Chengdu, Lanzhou) with 70GW+ nameplate capacity scaling toward 100GW, plus overseas bases in Vietnam (operational 2024, USD 99M investment), Ohio (trial production with H.B. Fuller), and Istanbul (trial production expected 2026). Channel partners include Sunket (global BIPV distribution), Shenghong Petrochemical (exclusive India distribution), and H.B. Fuller (US technology licensing). Named end customers include Tongwei, Yidao New Energy, SAIC Zhiji, BYD Yangwang, Fuyao Glass, and Mercedes-Benz.

Direct peers

• Hangzhou First Applied Material Co., Ltd. (Foster, 福斯特): Global #1 PV encapsulant film manufacturer and HIUV's most direct competitor. Both produce EVA, POE, and EPE films for solar modules and serve the same Tier-1 module customers including Tongwei. Foster's substantially larger scale and vertical integration set the industry benchmark that HIUV competes against on both cost and technology.
• Cybrid Technologies Inc. (赛伍技术): Major Chinese PV encapsulant film and backsheet manufacturer with overlapping EVA and POE film product lines. Competes with HIUV across TOPCon, HJT, and BIPV segments and serves similar Chinese module manufacturers, making it a closely comparable mid-tier player in the same specialty polymer films category.
• Lucky Film Co., Ltd. (乐凯胶片): State-affiliated Chinese manufacturer of PV backsheets and encapsulant films with significant domestic PV module supply relationships. Overlaps with HIUV in EVA-based encapsulant films and solar-grade polymer films, though its heritage in photographic film gives it different scale dynamics in specialty polymer manufacturing.
• Krempel GmbH: German specialty films manufacturer producing PV backsheets and encapsulant films with strong European module-maker relationships. Comparable to HIUV as a non-Chinese specialty encapsulant supplier with focus on quality and reliability rather than commodity scale, serving similar downstream solar and adjacent industrial film applications.
• Coveme S.p.A. Italian PV backsheet and encapsulant film manufacturer serving global module producers with specialty coated films. Comparable to HIUV's specialty encapsulant film business in product format (coated/laminated films for solar modules) and target customer base (European and global PV module manufacturers).
• Madico Inc. US-based manufacturer of specialty coated films including PV backsheets and protective films for solar modules. Comparable to HIUV in specialty film manufacturing process (co-extrusion and coating) and serves a similar B2B customer base of PV module manufacturers, though with a more North American geographic focus.
• Gentex Corporation: US-based leader in automotive dimming technology, primarily for interior rearview mirrors but increasingly extending to larger glass surfaces. Highly comparable to HIUV's PDCLC automotive dimming film business given overlapping automotive OEM customers and the shared trend toward smart, switchable glass in vehicle cabins.
• Gauzy Ltd. Israel-based PDLC and SPD smart glass film manufacturer serving automotive, architecture, and consumer electronics. The most direct technology competitor to HIUV in PDCLC dimming films, particularly for automotive sunroofs and architectural applications where both companies target switchable glass integration.

Broad incumbents

• Saint-Gobain: Global building products and high-performance materials giant offering electrochromic and switchable smart glass solutions for automotive and architectural applications. Competes with HIUV's PDCLC dimming film in automotive smart glass through broader glass-and-coatings portfolio rather than as a pure-play dimming film supplier.
• View, Inc. US-based smart glass specialist offering electrochromic glass for architectural and transportation applications. Adjacent competitor to HIUV in the broader switchable/smart film category, though View focuses on electrochromic technology versus HIUV's PDCLC approach and serves predominantly architectural markets.
