Isola Joins the Principal Mineral Family

Today, we announced that Isola has joined Principal Mineral.

For more than 100 years, Isola has been a premier global manufacturer of copper-clad laminates and dielectric prepregs – the high-performance materials at the heart of printed circuit boards. Our products are trusted by leading companies across aerospace, defense, communications, automotive, industrial, medical, and advanced electronics markets, supported by manufacturing, R&D, technical, and commercial operations across Asia, Europe, and the United States.

That legacy – built by generations of talented people across our global facilities – is the foundation this next chapter is built on.

Principal Mineral is dedicated to forging resilient supply chains for the strategic materials that power advanced technology applications across major industries. The company is a leader in rebuilding the industrial “missing midstream” of the strategic materials supply chain – the critical layer between upstream metals and the finished technologies used in advanced applications including aerospace, AI infrastructure, energy security, and communications equipment such as low earth orbit satellites.

Nothing changes in how we work with our customers or suppliers and our manufacturing, sales, technical, customer service, and supply chain teams will continue supporting them with the same dedication and responsiveness they’ve always relied on from Isola.

This combination creates a more vertically integrated, resilient platform, one that is capable of serving customers with greater supply security and a broader range of capabilities than ever before.

Isola is positioned for an exciting new phase of growth.
