It is normally copolymerized with other substances to improve its properties. Delrin behaves like most engineering materials in that as temperature increases, elongation increases and strength decreases. Properties of Polymers. This means, for example, that you can move a point and see how the section properties such as area or inertia evolve as the movement is occurring. The properties of the polyacrylate nanoparticles and latex film can thus be controlled by changing fluorine contents, which in turn provides key insights into the design of functional polymer material. In the Glassy state, the plastic is brittle; in the Rubbery or Viscoelastic state, the plastic is soft and/or tough and in the Melt state the plastic is molten. Even though ABS plastics are used largely for mechanical purposes, they also have electrical properties that are fairly constant over a wide range of frequencies.
