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.
