  • Plastics Processing Applications: Wood-Plastic Composites
    of Wood-Plastic Composites typically uses a fine wood waste (cellulose based fiber fillers such as hardwood, softwood, plywood, peanut hulls, bamboo, straw, etc.) mixed with various plastics (PP, PE, PVC). The powder is extruded to a doughlike consistency and then extruded to the desired shape
  • Long-glass-fiber PP hits the road
    Long-glass-fiber-reinforced polypropylene is proving its worth in a wide range of automotive applications. LNP Engineering Plastics, a GE Plastics Co. Edited by Jean M. Hoffman The Twintex process commingles the PP resin-fiber and glass-fiber filaments into one roving. The roving is then processed

  • Laser Cutting Polymeric Plastics
    To-day, almost in every endeavor of human existence we come across items made of plastic material. Over the past 50 years usage of polymeric (plastic) material (e.g. PVC, PE, PC PP etc.) throughout the world has increased dramatically, hundreds of millions of tons. Polymers are divided into two

  • Weathering of Plastics (.pdf)
    of plastics, e.g. it is around 300 nm for PE and around 370 nm for PP. Location. The amount of UV present in the incident solar radiation varies dramatically with location and is. particularly high near the equator. Climate change processes, particularly those that deplete the. ozone layer, have resulted
  • Introduction to Plastic Modular Belts
    different plastics; PP (Polypropylene), PE (Polyethylene), and POM (Acetal). Other plastics are available, but are not as common as the aforenoted types. Each plastic type has its own unique set of characteristics that affect the function of the conveyor belt. Some of these important traits include
