What Jiangsu Sidike New Materials Science&Technology does

Jiangsu Sidike New Materials Science & Technology Co., Ltd., founded in 2006 in Taicang, Jiangsu Province and headquartered in Sihong, is a publicly listed (Shenzhen Stock Exchange, ticker 300806, IPO November 2019) Chinese manufacturer of functional film materials and electronic-grade adhesives. The company operates across four product categories: functional film materials (anti-scratch, anti-glare, anti-reflection, hard-coated films for displays and electronics); electronic-grade adhesive materials (double-sided tapes, OCA optical adhesives, explosion-proof films, conductive tapes); thermal management composite materials (graphite and graphene thermal interface materials for consumer electronics, electric vehicles, and medical devices); and BOPP packaging tapes. Its competitive core is precision coating technology and in-house polymer synthesis (adhesive self-formulation, 胶水自制), delivered through an embedded R&D model where Sidike engineers work directly with end customers. The company supplies Apple as sole domestic supplier of iPhone surface protection film (since 2016), Tesla as sole supplier of elastic thermal conductive components for Model 3 (since 2017), Foxconn under a strategic partnership (since 2018), Samsung as a qualified supplier (since 2010), and additional tier-1 customers including Facebook, Lingyi (领益), and Biel Crystal (伯恩). Manufacturing is anchored by a 22,000 sqm Class 100 clean coating workshop in Sihong, with additional plants in Taicang and Dongguan, and wholly-owned overseas subsidiaries in the USA (Santa Clara), Vietnam (Bac Ninh), South Korea (Suwon), and Thailand (Chonburi) for sales and regional production. The company emphasizes R&D intensity above 8% of revenue, a 1,700+ patent portfolio (including 160+ invention patents), and strategic research alliances with Fraunhofer Institute (Germany), Tsinghua University, Southeast University, Suzhou University, and Nanjing University of Technology, targeting polymer formulations, MLCC release films, OCA optical adhesives, graphene thermal materials, and foldable OLED display films.
