The Riblene® range comprises a range of LDPE resins for a wide range of finished products; from the most simple to the most sophisticated items.

Riblene® is the trade name for versalis spa Low Density Polyethylene (LDPE) that is produced by high pressure technology.
Initiators’ decomposition starts ethylene radical polymerization and the reaction takes place at high temperature and high pressure conditions.
The resulting polymer is composed by branched macromolecules of polyethylene, having both short and long chain branches.

The mechanical, thermal, optical and electrical properties of Riblene®, its chemical resistance and processing characteristics make this resin suitable for many specific fields of applications.

Riblene

Versalis supply a range of ethylene vinyl acetate co polymers (EVA) under the trademark Greenflex®.

The products are made by the high pressure polymerization process adding the comonomer (vinyl acetate) into the main polymer chain based on ethylene monomer.
The technology and the type of polymerization (radical) rend these copolymers a special modification of common LDPE materials.

The main properties of EVA copolymers are different from the typical one of common LDPE polymers and the difference grows according to the increase of VA content. The range extends from properties similar to LDPE to rubber-elastic like properties for high VA content EVA copolymers.

Greenflex

Clearflex® is a (V)(UL) LLDPE that is known for its flexible properties.

Clearflex®, LLDPE family with butene or hexene comonomer and VLDPE with butene comonomer. These polymers are specialties used for lamination, stretch hood, stretch, BOPE, rotomolding and injection molding.

Clearflex® has excellent sealing properties, a high transparency and an outstanding mechanical performance.
