                                         Information @ a Glance
General
  • Olefin, also known as polypropylene or polyethylene, is a long-chain polymer synthetic fiber. It is created when ethylene
    and/or propylene gases are polymerized under very specific conditions.
  • Olefin was first manufactured in the late 1950s, and has a myriad of applications in manufacturing, household products and clothing. Use of olefin has steadily increased since the 1960s, and continues to gain in popularity every year as new uses for this easy, durable material are found.

Process

  • Olefin is created when the polymers are melted to a liquid, then run through a machine called a spinneret, which forces the product into a long fiber through small holes. This fiber is then used to make the fabric, or the end product in which it
    will be used.
  • Olefin resists dyeing, any dye must be added during this melting process, instead of to the final fabric or product. It is
    highly favored due to its easy, inexpensive manufacturing process. Surprisingly, olefin is relatively environmentally
    “friendly” due to the few byproducts produced during manufacturing. Olefin is also easily recycled.
     

Application

  • Ethylene a-olefin plastomers of about 0.9 density and 1.0 melt index are excellent materials for designing TPO formulations for single-ply roofing applications.
  • Catalytic transformation of seed oil via olefin metathesis.
  • Application of Olefin Cross Metathesis in Natural Product Synthesis.
  • The most important applications of olefin metathesis in the field of petrochemicals are the olefins conversion technology
    (OCT) process (originally the Phillips triolefin process) and the Shell higher olefins process (SHOP).
     

Market

  • The global olefins business is enjoying a period of unprecedented high capacity utilization rates.
  • Olefin has been kept tight by robust demand due to sustained high economic growth rates (particularly in Asia), and on the other hand, supply has been affected on account of delays in several major projects and feedstock restrictions.
  •  strong and resilient global economy continues to drive demand growth for light olefins.
     

Report

  • Toxicity test results show that olefin and paraffin SBF are non-toxic to the water-dwelling organisms studied. However, when sediment toxicity tests are considered, internal olefin and some alpha olefin products have significantly less toxicity
    compared to most paraffin materials.
  • Olefins are similar to paraffins but contain at least two fewer hydrogen atoms providing at least one double bond between
    adjacent carbon atoms. Olefins with one double bond have the general formula CnH2n.
  • Olefins can be produced from refinery streams or synthesized via ethylene oligomerization. Refinery olefins are highly
    branched while synthetic olefins are highly linear.
