PE ist für die Herstellung von Zahnrädern, Rollen, Stützelemente, Führungen, Schutz, Schrauben, Platten, Stützringe, Abstandshalter, Pumpenteile, Bauteile für Verpackung-und Abfüllungsmaschinen, Trichter, Komponenten für Papierfabriken und Drehmaschinen, Gleitkufen , Räder und Behälter für Lebensmittel und Getränke.

Polyethylen ist eines der am häufigsten verwendeten Kunststoffe. Dank der sehr guten Reibungs- und Verschleißfestigkeit, den hervorragenden elektrischen Eigenschaften und der guten chemischen Beständigkeit ist PE für alle Anwendungen in dem Industrie-, Lebensmittel-, Elektro-, Hydraulik-, und Textilbereich geeignet.

INTRODUCING PE

The polyethylene (PE) is a thermoplastic material belonging to the family of polyolefins, polymers composed of hydrocarbons having the formula CnH2n with a double bond (ethylene, propylene, butylene). For industrial uses polyethylenes are divided into different classes depending on the density and the degree of branching (PE 300, PE 500, PE 1000 or PE-LD, PE-HD, PE-LLD, PE-HD-HMW, PE -HD-UHMW). There are also special variants of polyethylene, such as PE-X (cross-linked), PE + PSAC (biodegradable) and PE-C (chlorinated).

Polyethylene is not a critical substance to work with and the wide range of existing PE covers a very wide range of processing conditions (injection molding, blow molding, extrusion, compression molding, welding and machining).

Generally, the PE has low density, stiffness and hardness, resilience and high elongation at break, good friction behavior and wear, outstanding electrical and dielectric characteristics. The tensile stress increases linearly with the density. The absorption of water and the water vapor permeability are low. The permeability to oxygen, carbon dioxide, and in many aromatic substances is remarkable. The permissible temperature range for short-term use are between 80 ° C and 120 ° C, while for long-term uses ranging from 60 ° C to 95 ° C. And ‚resistant to water, saline solutions, acids, alkalis, alcohol and gasoline. It is not resistant to halogen and to strong oxidizing agents, such as fuming sulfuric acid, concentrated nitric acid, the acid nitration and the Sulfochromic acid. And ‚odorless, tasteless and physiologically harmless, the latter feature that makes it suitable for use in the food industry. To improve their characteristics can be added glass fibers, UV stabilizers, flame retarding agents, antistatic agents over time resistant, anti locking agents and, finally, other additives to increase the electrical conductivity.

The polyethylene has various fields of application, depending on the density of the material. The PE-LD and PE-LLD are mainly used for the production of films, films, bags, agricultural sheeting, coatings for cables and for pipes and waterproofing membranes. The PE-HD is used especially for the production of containers, bins, baskets, canisters and tanks, besides being used for the construction of fittings for drinking water pipelines and equipment for the chemical and automotive industry. The PE-HD-UHMW is usually used for the realization of blocks and slabs for filter, external coatings of hoppers, transport slides and various components for machines, such as screws, gears, rollers, slide rails, rolling cylinders, honeycomb structures and parts for pumps.
