Eastman Therminol® heat transfer fluids can be found in the process of creating medium-density fiberboard (MDF). An in-use application, medium-density fiberboard is created by breaking down wood into wood fibers. Those fibers, along with other materials, are then transformed into panels. Heat transfer fluids are used to ensure precise temperature control when fusing the materials together. MDF is well-known for its density, stability, and durability—being generally stronger than plywood or particle board—and for its smooth surface quality.
