Polyurethane is a highly versatile raw material. It can be used for producing countless types of products for both interior and external parts, machinery covers, panels, handles for machines, and even flexible products, such as pillows and mattresses. Polyrit has a deep understanding of the fact that each raw material has its own set of physical traits and that various standards apply to every one of them. Polyrit continually makes sure that their clients get a wide range of polyurethane producing options while delivering the most precise and high-quality results.

Rigid Polyurethane

Rigid polyurethane provides an excellent solution for producing strong, yet lightweight products for many uses that require a high level of precision. It’s suitable for easy casting and painting that enables completing the visual appearance as required by the customer. The properties of the rigid polyurethane are– a combination of lightweight and flexibility along with a hard and designed exterior surface, enabling the creation of custom-designed products.

3 main categories define this type of material:

  1. Compact Rigid Polyurethane:

A rigid high-density material for 3-12 mm wall thickness with/without fillers.

Can be matched to various properties or needs from small to very large parts.

Suitable for covers and housing with excellent accuracy for combined assemblies that provide an excellent solution for manufacturing rigid parts for diverse uses that require a high level of precision for integrated assemblies, such as design molded casing and covers. This material suits production of customized machine covers upon customer request, with varying levels of strength, rigidity, flexibility, friction durability, cracking resistance and thickness.

Compact – Polyrit creates covers for many industries using compact rigid polyurethane. For example – designed covers for big printers up to sensitive medical equipment, such as CT and MRI devices. Compared to plastic, polyurethane is more insulated, better noise-absorbent, and inflammation-resistant. , In a matter of production volume, it is possible to produce housing covers  in medium quantities to  relatively small amounts (from a few hundred to tens of thousands of product units  The use of polyurethane for molding is less expensive making it highly profitable without compromising quality.

  1. Foamed Rigid Polyurethane

Rigid material with Low to medium density, especially suitable for wall parts over 5 mm thick.

It’s recommended for products that require lightweight covers of any size, for instance: panels for medical device covers, electronic systems cover, etc.

  1. Rigid Polyurethane for Thermal and Acoustic Insulation

The material has a high capacity of thermal and acoustic insulation. Due to its low thermal conductivity, polyurethane is an excellent material for products that require minimizing heat transfer for ambient temperature. This feature was made possible thanks to the spatial structure of the material, which consists of small and closed cells. Its most popular configuration is insulation plates of different sizes for various applications, such as insulated food transfer containers, isolated medical aid transport containers, etc.

On the other hand, polyurethane for acoustic insulation consists of open cells that provide the material with the required noise-absorption quality. As a rule, the structure of the material is stable and unchanging, hence the insulation quality retained for many years.

Semi-rigid polyurethane

Semi-rigid polyurethane is excellent for creating a high level of external and internal visibility. It’s an ideal material for manufacturers who are oriented towards the slicked and fancy exterior.

The semi-rigid polyurethane contains special additives to enhance its texture and qualities and is suitable for numerous applications, such as fenders, handles, all kinds of equipment. Semi-rigid polyurethane is also available in the foamed version.

Foamed Polyurethane

Molded foamed polyurethane is intended for creating products that are pleasant to touch. It’s available in many levels of rigidity and sizes and according to different standards. Molding the sponge-like polyurethane can be applied upon a core composed of many materials (for example, metals, wood, and more) or on its own. Of course, following the design and planning requirements of the customer. The most popular form of foamed polyurethane is seat pillows, backs, and headrests used for trains, buses, etc.
