With a global reputation for material development, Trelleborg Offshore Boston, Inc. is recognized as a leading manufacturer of advanced glass microspheres and high performance syntactic foams which are used in such markets as aerospace, defense, tooling products and buoyancy materials. Established in 1948, the company was the first to offer a complete line of commercially available aerospace grade glass microspheres through the Eccospheres® glass microspheres brand and has continued to focus on material innovation ever since. Further enhancing the product range, the company developed a wide range of fibre coated macrospheres (0.5 inch diameter hollow spheres) for incorporation into their syntactic foams. This led to the introduction of low density composite syntactic foam systems ideally suited for deepwater buoyancy applications. Throughout the next four decades, Trelleborg Offshore Boston, Inc. became the largest manufacturer of volume syntactic foam in the world - producing more than 50,000 drill riser and production buoyancy modules. The company has continued to evolve, achieving ISO accreditation in 1991. In 1995, the composite materials section of the business was separated and sold to become Emerson & Cuming Composite Materials, Inc. This heralded a period of major investment and rapid product development with further expansion into the oil & gas and aerospace markets. Trelleborg Offshore Boston, Inc.'s products are to be found in many applications within these markets including lightweight composite panels, jet engine vanes and thermal insulation.
