What Huakai Fengshi Technology (Chongqing) Co. does

Huakai Fengshi Technology (Chongqing) Co. (华凯丰石科技(重庆)有限公司), also operating as Kerryya (Chongqing) Co., Ltd., is a Chongqing-based Chinese specialty chemicals manufacturer of glass interlayer films and the upstream PVB resin used to produce them. Founded in 2010 as a subsidiary of Huakai Group, the company operates a 23,000 sqm facility in Rongchang District, Chongqing with 15 production lines dedicated to PVB resin, PVB film, SGP ionoplast film, and EVA film. The company was the first in China to independently develop PVB resin powder as a raw material input for its own film production (2013) and built China's first SGP ionoplast membrane production line (2016), establishing a vertically integrated position from resin polymerization to finished interlayer film. Product variants span architectural, automotive, solar/PV, sound-insulation, thermal-insulation, thermochromic, frosted, gradient-color, and HUD wedge-shaped films, with a stated 100% pure resin composition (no recycled content) and CTC certification for building and automotive grades.

The company's commercial model is B2B enterprise field sales with quotation-based, non-publicly-disclosed pricing and multi-year contracts. Customer mix is project-driven across construction (curtain walls, glass bridges, walkways, commercial centers), automotive (windshields, HUD, side windows), hospitality, healthcare, and greenhouse agriculture, with EVA products positioned for photovoltaic module encapsulation. Distribution is primarily direct enterprise sales through Mr. Jackie's overseas representation, supplemented by a Samarkand, Uzbekistan warehouse serving Central Asia, a Bossgoo B2B marketplace listing, and a 10-language website targeting international markets. Exports account for 81-90%+ of revenue, with verified market activity in China, Uzbekistan, Russia, Korea, and the UAE.

Strategic posture is internationalization and scale: the company entered overseas markets in 2019, established three Group subsidiaries in 2020, received two invention patents in 2024, secured Green Label certification in 2025, and began trial production of an ultra-wide 4.6-meter PVB/SGP line in December 2025. R&D is anchored by a 2017 strategic cooperation with South China University of Technology through the National Engineering Research Center for New Polymer Equipment. Headcount is stated at 501-1,000+ on the company website (versus 101-250 in third-party firmographic data), reflecting ambiguity; total invested capital is 130 million RMB with fixed assets exceeding 70 million RMB. No revenue figures, institutional investors, or public-listing information have been disclosed.

Core offering

Huakai Fengshi Technology (Chongqing) Co. manufactures and sells polyvinyl butyral (PVB), SentryGlas Plus (SGP), and ethylene-vinyl acetate (EVA) glass interlayer films, together with PVB resin used as the upstream raw material. Its films are supplied to laminated glass producers serving architectural, automotive, solar/photovoltaic, and security (including bullet-resistant) applications. The company also offers specialized variants such as acoustic/sound-insulation, color, gradient, HUD wedge-shaped, thermal-insulation, thermochromic, and frosted films.

Product overview

Huakai Fengshi Technology (Chongqing) Co. is a manufacturer specializing in glass interlayer films. The product portfolio centers on three core film types: PVB (polyvinyl butyral) films for architectural, automotive, solar, and specialty glass applications; SGP (ionoplastic) films for bulletproof and structural glass; and EVA (ethylene vinyl acetate) films primarily for photovoltaic module encapsulation and architectural glass. The company offers extensive product variants including colored films, gradient films (including double-sided gradient and HUD wedge-shaped variants), sound insulation films, thermal insulation films, thermochromic films, and frosted films. The product lines are differentiated by application (high-end architectural, automotive, sound insulation, bulletproof) and are manufactured using 100% pure resin with no recycled materials. Current production capacity includes 15 production lines with annual output of 99,500 tons of PVB resin, 27,000 tons of PVB film, 17,000 tons of SGP film, and 13,000 tons of EVA film.

Broad incumbents

• 3M Company: Diversified industrial conglomerate with specialty films, adhesives, and safety products serving construction and automotive markets. Adjacent rather than directly competitive; comparable as a broad incumbent with overlapping customer base but not a focused PVB/SGP film supplier.
• Saint-Gobain SA: Global building materials and glass manufacturer producing laminated glass products (downstream of Huakai's interlayer films). Indirectly comparable as it sets end-market specifications and is a potential customer, but operates at a different layer of the value chain.
• Mitsubishi Chemical Group Corporation: Japanese chemical conglomerate producing specialty polymers, EVA, and engineered films across multiple industrial applications. Broad incumbent with capability overlap in EVA and polymer film space but no focused PVB/SGP interlayer franchise comparable to Huakai's core.

Direct peers

• Kuraray Co., Ltd. Kuraray's Trosifol business is the global leader in PVB and SGP interlayer films for laminated safety glass in architectural and automotive applications. Direct competitor to Huakai across both PVB and SGP product lines, serving the same laminated glass converter customer base worldwide.
• Wacker Chemie AG: Wacker manufactures EVA films (including solar-grade) for photovoltaic module encapsulation and other specialty applications. Directly overlaps with Huakai's EVA film business serving solar panel manufacturers and high-end glass laminators.
• Eastman Chemical Company: Eastman's Saflex business manufactures PVB interlayer films primarily for automotive windshields and architectural laminated glass. One of the two global incumbents alongside Kuraray, competing directly with Huakai's PVB film portfolio in OEM and converter channels.
• Sekisui Chemical Co., Ltd. Sekisui's S-LEC division produces PVB interlayer films for automotive and architectural laminated glass. Comparable to Huakai in product scope and customer segments, with strong Japanese OEM relationships as a structural advantage.
• Hangzhou First PVB Film Co., Ltd. Chinese PVB interlayer film producer focused on architectural and automotive applications. Comparable to Huakai as a domestic Chinese competitor targeting similar laminated glass converter customers.
• Chang Chun Petrochemical Co., Ltd. Taiwanese chemical manufacturer producing PVB resin and related polymer materials used in laminated glass interlayers. Competes with Huakai at both the upstream PVB resin level and as a regional PVB resin/film supplier in Asia.
• Jiangsu Darui New Materials Co., Ltd. Chinese manufacturer of PVB and SGP interlayer films for architectural and automotive laminated glass. One of the closest domestic competitors to Huakai, competing on similar product mix and customer base within China and export markets.
