granulo polietilene materia prima



Linear low-density polyethylene is available on the market in many grades with differing comonomer contents (butene or hexene), which give different characteristics to the product. The density can vary from 0.915 to 0.945 g/cm³, which comprises the density spectrum of both LDPE and HDPE. The branches in the macromolecule, which are formed from these comonomers, have a very significant effect on some of the properties of the final polymer; in fact, they influence the density value, whose increase is correlated with an increase in thermal and mechanical resistance. LLDPE is requested for its high tenacity, puncture resistance, and stress cracking resistance.

Linear Low-Density Polyethylene (LLDPE)


Semi-crystalline Polymer


Addition polymerization through the Ziegler or Philips catalysts, used in a solution or in a gas phase, obtains (from catalytic processes) a copolymerization of a comonomer (butene, hexene, or octene) in the ethylene chain (copolymerization).




  • Dimensional stability
  • Resistance to hydrolysis
  • Low coefficient of friction
  • Excellent resistance to corrosion and chemicals
  • Low permeability to gases and vapors
  • Optimal flexibility at low temperatures
  • Optimal impact resistance at room temperature and cold temperatures
  • Lightness
  • Non-toxic
  • Odorless and tasteless
The heart of our production is extrusion and with this process we generate wounded linear tubes or straight cut pieces of tube. With further processing, we produce other types of products and we finally combine accessories and other items to complete the range.

Single, flexible, non-thermoformed tube, wrapped in coils of various lengths.


  • small footprint;
  • long distances seamless.


  • elastic memory of the winding;
  • tolerance on the cut of +/- 2% of the length.
