WebStresses in the core affect not only the mechanical but also the magnetic properties. It is apparent that the initial permeability is dependent on the stress state of the core. The higher the stresses are in the core, the lower is the value for the initial permeability. Thus the embedding medium should have the greatest possible elasticity. WebPolytrimethylene Terephthalate (PTT) is a semicrystalline polymer that has many of the same advantages as its polyester cousins, PBT and PET. Compared to PBT, compounds composed of PTT exhibit better tensile strengths, flexural strengths, and stiffness. They also have excellent flow and surface finish. PTT can also be more cost effective than PBT. WebReinforced Polyethylene terephthalate with 15% glass fiber.
