There’s nothing more frustrating than purchasing plastic fasteners and having them fail after you install them in your application.
Plastic can fail in a multitude of ways, from cracking, creeping and deforming to fading. Different kinds of plastics are vulnerable to a wide array of elements, including UV rays, processing chemicals, water and saltwater, and more. Unlike metal, which bends before breaking, giving the user a warning that the part needs to be replaced, … Read more
Ultrasonic welding is a method of bonding together two parts made of the same or chemically compatible materials using high frequency ultrasonic vibrations that create a solid state weld between them. The advantage of using this technique with plastics is that within seconds a high strength, gas and water tight bond is formed without screws, glue, threads, solder or any other type of bonding material. Parts that have been welded do not need to be left in a jig for curing, … Read more
One of the most popular plastics available today, Nylon was first patented in 1935 by
Wallace Carruthers, a scientist working for Dupont®. Nylon is a thermoplastic made from petrochemicals. It is a semi-crystalline plastic, that it has both amorphous (unstructured) as well as crystalline (structured) regions. When heat is applied it does not begin to slowly melt like amorphous resins, rather it stays firm until it reaches its melting point and then melts all at once. … Read more
Fiber reinforced plastic (FRP), also known as fiber reinforced polymer, is in fact a
composite material constituting a polymer matrix blended with certain reinforcing materials, such as fibers. The fibers are generally basalt, carbon, glass or aramid; in certain cases asbestos, wood or paper can also be used.
The Formation of FRPs
Going back to the basics, there are two processes through which a polymer is developed: step-growth polymerization and addition polymerization. … Read more
