Basalt is an extrusive igneous rock that is formed when lava is exhumed from a volcano and cools rapidly on the surface of the earth so that only smaller crystals are able to form. It is the most common volcanic rock on the planet; lining the oceanic crust as well as many of the volcanic islands. However, in order to turn this volcanic rock into a cloth to be made into a composite material it must go through a separation and extrusion process. Interestingly enough, it is processed much like steel. The raw material is melted, poured into a teapot shaped vessel (skimmer) where most impurities are separated by differences in specific gravity and (like slag from steel), forced out the teapot spout, and then extruded into filaments.
Lamitex® laminated plastics are used in numerous applications where they are either submersed or are in constant contact with corrosive chemicals. The degree of chemical resistance of the laminate will depend on the nature and concentration of the chemical agent along with temperature and duration of exposure. The ease of fabrication, light-weight, and resistance to friction, light, and heat are other major advantages for Lamitex composites in these applications.
Our years of experience dealing with the steel and hot rolling industries have led us to one conclusion; for these guys, time is money. Being able to keep a mill running longer between the change-out times is a topic that appeals to both mill maintenance and purchasing alike. Here at Franklin; we have found an answer to this issue in the form of our Lamitex® grade SBE100.
