What is an Epolene Polymer?

  • Medium to low molecular weight polyethylene and polypropylene polymers
  • Produced in 4 operating units in Longview, TX
  • 3 basic types of polymers which are called C, E, and N-type polymers
  • Products supplied as free flowing pellets; powder form available for some products
  • Products packaged in 50 lbs bags; some alternative package sizes available
