Market Trends

The electrical insulation materials industry is expanding at a compound annual growth rate (CAGR) of approximately 6.6% to 7.1%, with the market size projected to grow from around USD 1.19 billion in 2024 to USD 2.25 billion by 2034. This growth is driven by the upgrade of power infrastructure, the development of smart grids, the adoption of renewable energy, industrial automation, and the continued rise of electric vehicles.

On the materials side, new high-performance, lightweight, thermally stable, high-voltage-resistant, and environmentally friendly composite materials are continuously emerging. In addition, the global transition toward clean energy and the expansion of natural gas trade have positioned LNG carriers and fuel vessels as key growth drivers in the future shipbuilding industry. Both categories of materials are undergoing rapid development and present enormous market potential.
