  • Plastics Processing..... How Plastic Resin Becomes Pipe, Valve, Etc.
    Pipe is one of the more common types of plastic product we are familiar with. Pipe is produced by an extrusion process. Basically extrusion can be defined as forcing a material through a die orifice. This die orifice produces the final shape of the finished product. It is probably a bit of over
  • New resin helps make direct manufacturing practical
    A second-generation noncrystalline, nanoparticle stereolithography (SL) resin lets VG Kunststofftechnik in Germany manufacture limited production runs of small, detailed parts. VG Kunststofftechnik uses NanoForm 15120 to regularly produce up to 200 directly manufactured parts for pre and limited
  • Plastic Compounder's PET Project: Recycling
    Plastic water bottles can be "upcycled " into durable materials with properties equivalent to virgin polymer. Platform Technology Manager, Crystalline Polymers Div. Talking about going green has become a national pastime in recent years. Implementing energy-saving processes, using recycled
  • Plastic Bearings
    loads. Composite materials that consist of cotton fabric, or other fillers bonded with phenolic resin. The compatibility of the phenolics makes them easily lubricated by various fluids. They have replaced wood bearings and metals in such applications as propeller and rubber-shaft bearings in ships
  • Water Activity and Plastics (.pdf)
    One of the advantages of plastics is their freedom from attack by ambient moisture conditions. However, in the resin state prior to processing, plastics can absorb moisture. Failure to remove this absorbed moisture from the plastic resin can result in surface defects in the final product
  • Medical Device Link . Predicting Cryogenic Impact Performance of Medical Containers from Resin Properties
    SHERWIN SHANG, MICHAEL T.K. LING, STANLEY P. WESTPHAL, AND LECON WOO In many cases, containers used in the medical industry are subjected simultaneously to subambient temperatures and mechanical stress. For example, flexible plastic containers used to harvest platelets from human whole blood must
  • Glass Bubbles Reduce Weight of TPO Parts (.pdf)
    Resin compounder Noble Polymers of Grand Rapids, Michigan, a subsidiary of Cascade Engineering, has developed a low-density polyolefin resin formulation that reduces the weight of TPO plastic parts by up to twenty percent. This masterbatch bulk resin additive incorporates hollow glass bubbles from
  • What are Typical Properties?
    When designing with high-performance polymers, it's important to understand the nature of plastic materials, their properties and testing methods. Only then can you evaluate the advantages and limitations of a particular resin and determine if it is suitable for your application.
