What Isola Group does

Isola Group is a global material sciences company founded in 1912 and headquartered in Chandler, Arizona, that designs, develops, manufactures, and markets copper-clad laminates and dielectric prepreg materials used to fabricate advanced multilayer printed circuit boards (PCBs). Its proprietary resin formulations and materials science capabilities span a broad product portfolio organized across performance tiers: ultra-low-loss high-speed digital materials (Tachyon 100G, TerraGreen 400G/400G2/400GE, I-Speed), very-low-loss halogen-free materials for multilayer PWBs (IS580G, IS550H), thermal-reliability polyimide systems (P95/P25, P96/P26), mid-to-high Tg FR-4 epoxies (IS400, IS420, 370HR, FR408HR), and RF/Microwave materials (I-Tera MT40). The company sells into seven primary end-markets: automotive and transportation, networking and communication systems (including 5G), RF/microwave, aerospace and defense, computing/storage/peripherals, consumer electronics, and medical/industrial/instrumentation.

The company's business model is B2B hardware sales of industrial materials through direct sales (regional contact centers covering Americas, Asia Pacific, and EMEA), a distributor network (including TCT Circuit Supply, EMX, and others), an online sample-and-buy channel, and a Quick Turnaround Program offering same-day delivery for compressed lead times. Pricing is quote-based and not publicly disclosed. End customers include PCB fabricators such as TTM Technologies and Calumet Electronics. The company operates a global manufacturing footprint and maintains extensive industry certifications including UL, IPC-4101/4103, IPC/JEDEC J-STD-709, RoHS, and ISO 27001.

In June 2026, Isola was acquired by Principal Mineral (a Southlake, Texas-based critical-materials company founded in 2024), combining Isola's copper-clad laminate production with Principal Mineral's copper foil manufacturing (via its 2025 acquisition of Camden Copper) to form the only vertically integrated Western foil-to-laminate platform. The transaction was supported by approximately $280 million in new funding co-led by Overmatch Ventures and The New Industrial Corporation, with a senior secured term loan from Lane42 Investment Partners and participation from J2 Ventures and Ensemble VC. The combined entity employs approximately 1,300 people across 10 facilities in North America, Europe, and Asia. Leadership includes Travis Kelly as President and CEO.
