Polyethylene

Polyethylene (PE) is one of the most commonly used plastics in the world, with a wide range of applications across various industrial segments and a diverse array of different applications. PE allows for cheap food packaging with extended shelf life, safe transportation and distribution of chemicals, supplying drinking water to populations, protecting new vehicles from scratches, and thousands of other useful applications used in daily life.

Polyethylenes (PE) can be divided into many groups based on properties that allow a wide range of applications for end users.

LDPE (low-density polyethylene) manufactured using tubular or autoclave technologies is available with standard (0.918-0.925 g/cm3) and medium densities (0.930-0.940 g/cm3). Together with very low concentrations of gel, LDPE also includes high-performance types for extrusion and injection molding and is available in qualities that meet food and pharmacological standards.

LLDPE (linear low-density polyethylene) - C8 octene, C6 hexene, and C4 butene types. LLDPE is available from higher densities (up to 0.941 g/cm3) to low-density PE (0.905 g/cm3). LLDPE (linear low-density polyethylene) is used for extrusion, blow molding of films, rotational molding, and injection molding for the production of food packaging, frozen food packaging, underfloor heating pipes, shrink films, packaging for cosmetics and pharmaceutical products, etc.

HDPE (high-density polyethylene); bimodal and unimodal for blown films, blow molding, injection molding, and other drawing processes. Individual types of HDPE are offered with UV stabilization and certification meeting the requirements of standards for blow-molded chemical containers.

Plastomers for modifying PE or PP serve to improve properties, such as sealing ability, impact resistance, or softness. Plastomers include a wide range of types, densities, and individual components of copolymers (polymer based on ethylene-octene or butene).

Functional polymers such as EEA, EAA, and MAH create adhesion to barrier layers of other polymers, such as EVOH or polyamide, during extrusion. These adhesives create a strong and reliable bond with other substrate materials during the co-extrusion process. EAA can also be used in aqueous solutions or as hot melt (in addition to metallocene polyolefin hot melt adhesive).
