Polyethylene

Uses and applications

Polyethylene: countless uses in every sector
Polyethylene is a chemically intert material that belongs to the polymers group. It is obtained from the polymerization of the ethylene that gives it its name. We offer a wide range of different types of polyethylene for all industrial segments in which our customers work: agriculture, the automotive industry, well-being and consumer products, building and infrastructure, packaging, health care, and for the home.

Ranges

UHMWPE, known as a "super polymer," is an extraordinary material thanks to its unique properties. It stands out for its high strength-to-weight ratio, low friction, and excellent abrasion resistance, making it an ideal choice for a wide range of industrial applications.

 

This versatile polymer is used in:

  • Construction materials, where it provides durability and structural strength.
  • Automotive and aerospace industries, due to its ability to withstand impact and wear.
  • Medical devices, where reliability and safety are essential.
  • Lead-acid battery separators, thanks to its chemical resistance and long-term stability.

Altogether, UHMWPE represents an innovative and efficient solution for industries that demand high-performance materials.

We offer an extensive range of high density polyethylene (HDPE), a product highly valued for its tenacity and rigidity for the blow moulding process and extrusion which is aimed at applications such as containers for dairy produce, cosmetics and detergents. Containers for chemicals, hazardous goods and petroleum derivatives. We also offer high density polyethylene for blow moulding, to make a very thin and tough film used, for example, to wrap fresh produce. HDPE is used in the manufacture of pressure pipes for water, gas and irrigation systems as well as for pipes intended for sanitation, drainage and cable protection.

This product offers properties such as good impact resistance, very good processability, heat and chemical resistance and greater flexibility than HDPE. 

 

We offer a very wide range of different grades for the manufacture of films, enhancing properties such as clarity, stiffness and density for an excellent finish. LDPE is widely used for manufacturing films for packaging, ranging from shrink film, industrial film, laminating, food packaging and sacks. It is also used in the manufacture of insulation and jacketing for telecommunications and power cables. In this particular speciality, Repsol has a strong presence due to the high quality of its products.

Repsol Resistex®

Repsol Materials is keen to offer its customers differentiated products. The company has taken one more step with a product called Repsol PE Ultraclean® for making film with very low gel content for laminating and protecting valuable item. Repsol has a new range of metallocene linear low density polyethylene (mLLDPE) under the Repsol Resistex® trademark.

The new differentiated metallocene linear low density polyethylene (mLLDPE) range, marketed under the Repsol Resistex® brand, is a product of maximum versatility that can be used for food packaging film in applications such as frozen bags or for industrial film used for shrinking pallets. This product offers high resistance to tearing and puncture and excellent transparency and gloss.
