Construction materials

We offer a wide selection of excellent quality plastics that are based on synthetic polymers and are therefore an excellent alternative to many traditional materials. Depending on the place and type of application, they will replace wood, metal structures, ceramics and plastic or natural rubber. Taking into account their unique physical characteristics, they will find a lot of wider use as they do not have counterparts as a group of new products and can therefore be used in a variety of ways.

These materials are characterized by low density, increased corrosion resistance and ease of processing. Thanks to their use, you can reduce the cost of mass production of parts, as opposed to the traditional materials mentioned above. Thanks to this, construction plastics have become very popular in the 20th century and today they can be found in many places.

 

 

Polyamide

Polyamide is a construction material belonging to the thermoplastic group. It is characterized by high strength, hardness, tensile strength, low specific gravity and self-lubrication. The combination of these features makes the material ideal to make components such as gears, pulleys, roller bearing cages, pump housings, slide bearings, sealing rings, rollers, control rollers, slides and more. Available in the form of sheets of thicknesses from 1 to 200mm, rods with a diameter of 6 to 250mm and tubes with an outer diameter of up to 250mm. In case of fire the polyamide exhibits self-extinguishing properties.

PTFE(Teflon)

PTFE is the main item in the fluorine group. Its specific properties make it an indispensable material in many industries such as chemical, electrical engineering, machinery, food, paper, textile.

PTFE is characterized by high resistance to most chemicals, wide temperature range of continuous operation from -260 oC to +260 oC, lack of water absorption and food contact. PTFE is white colour.

 

Typical applications of Teflon:

  • Sealing

  • Fittings

  • Valve parts

  • Insulation in electrical and electronics

  • Insulating

  • Guides

  • Sliding liners

  • Membrane
  • PTFE seals

Phenolic-cotton products (Textolit)

It belongs to the group of layered materials obtained by compressing at elevated temperatures several layers of cotton cloth impregnated with phenolic resin. It is a self-lubricating, self-tuning, silent, dirt-resistant material, characterized by exceptional mechanical stability over a wide range of temperatures. It is an electro-insulator and an excellent material for bearings and slides, roller bearings, sealing rings, guides, rolling elements and running tracks, wheels and rims, cams and other components requiring high reliability and maintenance-free operation.

It is available in the form of sheets mainly 1000 x 1000mm (optional 1000 x 2000m) as well as in the form of rods and tubes.

PCV

Polyvinyl chloride (PCV, PVC) is characterized by high chemical resistance and mechanical strength.
It is used in practically every industry to insulate or produce specific components (rails, coffers, trim strips, moldings, etc.). It is a very popular material in the advertising industry. In our offer we have sheets of different thicknesses and sizes. We also have the ability to cut the sheets to a specific dimension or even cut a particular piece.

Plexiglass and Polycarbonates

Plexiglass

Synthetic material used as a replacement for glass. It is available in both transparent and transmissive versions (about 92% for 3mm thick boards) as well as for tinted or damp of both solid and chambered structures.

 

Polycarbonate (PC)

Transparent plastic with very good mechanical properties used (among others) in aircraft, scooters, as fairings in motorcycles, or as glass substitute, where there is a high risk of braking.
