Polyethylene (PE) is a polymer synthesized mainly from ethylene (monomer). With the help of catalysts or pressure and temperature conditions in means of reaction, ethylene can react to form a hydrocarbon chain denominated Polyethylene.
The polyethylenes manufactured by Polinter marketed under the brand Venelene® are synthesized complying with technological standards and a strict quality control of all processes of the production chain, which starts with the Ethylene supplied by Petrochemicals of Venezuela, S. A. (Pequiven).
Polinter has been awarded the Norven quality seal in the production of Venelene® Polyethylenes.
Classification
There are different types of polyethylene (PE) that can be classified in many ways. According to the distribution shown below, the PE can be classified according to their density, whose range for the case of the Venelene® resins oscillates between 0.918 – 0.966 g/cm3.
Inferior values within the previous range correspond to Low-Density Polyethylene (LDPE) and Low-Density Lineal Polyethylene (LLDPE), whereas the superior values within the range are those from High-density Polyethylene (HDPE). Finally, intermediate densities correspond to Medium-Density Polyethylene (MDPE).
Grades according to classification
Venelene® polyethylenes are a family of products that comprise linear and branched low density polyethylenes, medium density polyethylenes and high density polyethylenes adjusted to the needs of the market and processability requirements, properties and final product performance for the different applications:
