PUR rubber sheet

PUR rubber sheets are made from polyurethane elastomers and are used wherever classic rubber sheets reach their limits due to abrasion, mechanical load or continuous stress. Typical areas of application are found in industry, mechanical engineering, conveyor technology and plant construction.

The material is characterised by very high abrasion resistance, good recovery properties and high tear strength. As a result, PUR rubber sheets are particularly suitable for applications involving sliding, rolling or impact loads, for example as wear protection, scrapers, backing or damping elements.

PUR rubber sheets are available from Martan Gummi as cut to size and can be precisely adapted to existing constructions. Further elastomer alternatives can be found in the rubber sheets section, organised by material and main application.

Properties and technical specifications of PUR rubber sheets

PUR rubber sheets are used specifically where high mechanical stress and continuous load occur. The technical properties are designed for wear resistance, dimensional stability and long service lives.

A key feature is the very high abrasion resistance. In direct comparison with classic elastomers such as SBR or NBR, PUR rubber sheets show significantly less material removal during sliding or rolling movements. This noticeably extends maintenance intervals and replacement cycles.

In addition, PUR rubber sheets have high tear and cut resistance. Even under point loads or sharp-edged contact, the material remains dimensionally stable. The good recovery elasticity ensures that the sheet returns to its original shape after loading.

The temperature range of PUR rubber sheets is designed to be practical for industrial applications, but is not the focus of this material. Likewise, the focus is less on chemical resistance and clearly on mechanical performance in continuous operation.

For applications where other properties are the priority, such as oil resistance or weather resistance, alternative rubber sheets based on other elastomers are available.

Typical areas of application for PUR rubber sheets

PUR rubber sheets are used primarily in areas where components are permanently subjected to mechanical stress and classic rubber materials would wear prematurely. The material is chosen specifically when abrasion resistance, cut resistance and dimensional stability are decisive.

In conveyor technology, PUR rubber sheets are frequently used as linings, sliding or impact surfaces. They protect metal constructions from wear and reduce material removal during continuous contact with bulk material, conveyor belts or rollers.

In mechanical and plant engineering, PUR rubber sheets serve as wear protection, scrapers or damping elements. The material also proves its worth with moving components that are regularly exposed to friction or impact loads, thanks to its long service life.

Further fields of application can be found in recycling technology, agricultural technology and in special industrial applications where a long service life and short maintenance intervals are required.

For applications with other priorities, such as weather or oil resistance, alternative rubber sheets made from other elastomers are available.

Cutting options and processing of PUR rubber sheets

In practice, PUR rubber sheets are frequently used as custom-cut rubber pieces, as they must be adapted exactly to existing components, machines or protective surfaces. Thanks to the high dimensional stability of the material, cut contours remain reliably intact even under continuous load.

Cutting is generally carried out as rectangles or contour-accurate to drawing. Holes, recesses or special geometries can be produced precisely, so that PUR rubber sheets can be supplied ready for direct installation.

During processing, it must be taken into account that PUR is significantly more resistant than classic rubber materials due to its high abrasion and cut resistance. Suitable cutting and machining processes are required for clean edges and exact dimensions.

PUR rubber sheets are suitable both for fixed bolting and for loosely inserted applications. The choice of fastening method depends on the load, the amount of movement and the maintenance requirements of the respective construction.

Distinction from other rubber sheet materials

PUR rubber sheets are used specifically when mechanical load capacity and abrasion resistance are the priority. Compared with other elastomers, they differ significantly in their property profile and their optimal area of application.

Rubber sheets based on SBR are suitable primarily for simple technical applications with moderate stress. They offer good elasticity, but achieve significantly shorter service lives than PUR in terms of abrasion and cut resistance.

NBR rubber sheets are preferably used when resistance to oils, greases or fuels is required. In highly abrasive applications, however, they reach their wear limits more quickly than PUR rubber sheets.

EPDM rubber sheets are characterised by very good weather and ozone resistance and are frequently used outdoors. For applications involving continuous friction or high mechanical stress, PUR is generally the more economical solution.

Selection guidance for PUR rubber sheets

When selecting PUR rubber sheets, the specific mechanical stress is the focus. The type and intensity of abrasion, the contact surfaces and the forces occurring during operation are above all decisive.

For applications with continuous sliding or rolling contact, a sufficiently dimensioned sheet thickness is recommended in order to achieve a long service life. For point loads or impact stress, attention should also be paid to a suitable material hardness.

The type of fastening also plays an important role. Bolted PUR rubber sheets offer high positional security under heavy loads, while loosely inserted cut pieces can offer advantages for maintenance and replacement.

In order to avoid overdimensioning or an unsuitable material choice, comparison with other elastomers based on the actual application profile is recommended. A structured orientation is provided by the overview of rubber sheets by materials and typical applications.

Frequently asked questions about PUR rubber sheets

What are PUR rubber sheets used for?

PUR rubber sheets are used when components are permanently exposed to abrasion, friction or mechanical load. Typical applications are found in conveyor technology, mechanical engineering and as wear protection.

What distinguishes PUR rubber sheets from classic rubber sheets?

The main difference lies in the significantly higher abrasion and cut resistance of polyurethane. In mechanically demanding applications, PUR rubber sheets achieve longer service lives than classic elastomers.

Are PUR rubber sheets oil- or chemical-resistant?

PUR rubber sheets are primarily designed for mechanical performance. For applications with heavy oil or chemical exposure, other rubber sheet materials are better suited.

Can PUR rubber sheets be manufactured to measure?

PUR rubber sheets are available as cut to size. Dimensions, contours and holes can be adapted to the respective application.

What alternatives are there to PUR rubber sheets?

Depending on the application profile, other rubber sheets made from SBR, NBR or EPDM may also be considered.
