  • polymers
  • In the experiment described in this paper, topographical and chemical changes were inserted on the surfaces of two conventional polymers (low density polyethylene and polytetrafluorethylene) by PIII with nitrogen ions, and under conditions mimicking the natural mineral formation processes. (springer.com)
  • This work is part of a wider investigation of the ability of PIII treated polymers (low density polyethylene, polytetrafluorethylene, 2103 and 2363 commercial Pelletane materials with medical applications and polyurethane synthesized from polypropyleneglycol and toluenediisocyanate, PPG-TDI) to induce calcium phosphate formation from an aqueous solution resembling the human blood plasma.

  • In this paper we study the modification of two conventional polymers, low density polyethylene and polytetrafluorethylene, by PIII with nitrogen ions, and their ability for calcium phosphate formation after the modification upon immersion in an aqueous solution of inorganic salts.

  • Branching, or the bonding of ethene monomers to hydrogen molecules to form polymers, also determines density. (wisegeek.com)

  • versatile
  • This process has proved to be a versatile way to recover polyethylene wastes into valuable oils (rich in aliphatic and simple aromatic hydrocarbons) or gas, to be used as petrochemical feedstock or fuel, thus providing a sustainable method for material and energy recovery of waste packaging.

  • Tanks
  • Replacement polyethylene gas tanks have no welds or seams and are guaranteed not to rust through for the life of your vehicle. (4wd.com)
  • organic
  • Therefore, there have been many attempts to improve the properties of polyethylene by blending it with organic or inorganic materials [ 6 - 14 ]. (hindawi.com)
  • produces
  • For instance, material produced by the addition of a free-radical initiator ( radical polymerization ) often produces a different polyethylene density than one made by the use of a catalyst, such as chromium and/or silica. (wisegeek.com)
  • Reliance produces the entire range of polyethylene with international standards and exports them to countries in Europe, Africa, Middle East, and Southeast Asia. (ril.com)
  • creep
  • However, there are some drawbacks with Polyethylene including low environmental stress cracking resistance, low creep resistance, and poor compatibility with various additives which restricted its use for cretin purposes [ 6 , 7 ]. (hindawi.com)
