SBR rubber sheet

The SBR rubber sheet is made from styrene-butadiene rubber and is one of the economical standard materials for technical applications. It is suitable for areas where mechanical load-bearing capacity, good abrasion resistance and an attractive price-performance ratio are the main priorities.

SBR is often used when contact with oils, greases or severe weathering plays a subordinate role. Typical fields of application are found in mechanical engineering, plant construction and in simple sealing, protective and backing solutions.

Compared with specialised elastomers, the focus with SBR is on functionality and cost efficiency. For applications with higher requirements for resistance or media resistance, it is worth looking at alternative rubber sheets made from other materials.

Properties of SBR rubber sheets

SBR rubber sheets are made from styrene-butadiene rubber and are used as a functional standard material. The material is suitable for applications with mechanical load and moderate ambient conditions.

The hardness is available in various Shore A ranges and can therefore be adapted to different pressure and damping requirements. The sheets are available in several thicknesses and cover a broad spectrum of technical applications.

The application range typically lies in a temperature window of around −30 °C to +70 °C. The surface is available smooth or embossed and can be matched to the respective purpose.

For classification within the range, a comparison with other rubber sheets that are designed for special media or ambient conditions is recommended.

Functional advantages in use

SBR is characterised by good abrasion resistance and is suitable for applications with recurring mechanical stress. The elastic material structure supports the damping of impacts and vibrations.

The material offers stable performance under changing loads and represents an economical solution for standard applications. Processing by cutting or punching is technically straightforward and can be implemented in a practical way.

Typical applications

SBR rubber sheets are used, among other things, in:

• industrial applications such as backing, protective mats or simple sealing solutions
• construction-related areas as impact sound or protective layer
• technical constructions in the vehicle and equipment environment
• functional floor and backing solutions in the sports and leisure sector

Dimensions and cut pieces

SBR rubber sheets are available in different dimensions and thicknesses. For specific requirements, precisely fitting cut pieces are suitable, matched to the respective area of application.

Distinction of SBR from other rubber sheets

SBR rubber sheets are suitable for technical applications with a focus on mechanical load-bearing capacity and economical implementation. Depending on the field of use, other elastomers offer additional properties that are relevant for special requirements.

Compared with EPDM, the focus with SBR is on abrasion resistance and cost control. EPDM offers advantages under permanent weathering and elevated temperature ranges and is therefore more suitable for outdoor applications or contact with environmental media. A more in-depth classification can be found under EPDM rubber sheets.

Compared with NBR, SBR positions itself as a solution for applications without contact with oils or fuels. NBR is preferably used in media-exposed environments, while SBR is designed for dry, mechanically stressed fields of application.

The selection of the suitable material depends on the temperature range, media contact and mechanical stress. Within the range of rubber sheets, SBR offers a reliable option for standardised applications.

Selection criteria for SBR rubber sheets

The selection of an SBR rubber sheet depends on clearly defined technical requirements. Hardness, thickness and the intended area of application are above all decisive.

The hardness influences the behaviour under pressure and load. Softer grades are suitable for damping applications, while harder variants offer greater dimensional stability. The choice of thickness depends on the mechanical stress as well as on design specifications.

SBR is suitable for dry application environments without permanent contact with oils or aggressive media. For applications with extended requirements, a comparison within the range of rubber sheets is recommended in order to select the suitable material in a targeted way.

For recurring applications or series requirements, a standardised design is advisable in order to ensure consistent material performance.

Cut pieces and delivery forms of SBR rubber sheets

SBR rubber sheets are available in common standard formats and material thicknesses. These are suitable for many technical applications in the industrial and commercial environment.

For specific installation situations, SBR rubber sheets can be cut to size. Precisely fitting cut pieces support clean integration into existing constructions and reduce material waste during further processing.

Depending on the application, rectangular cut pieces, strips or simple moulded parts are used. The choice of delivery form depends on the intended purpose as well as on logistical and assembly-related requirements.

For better classification within the range, a comparison with other rubber sheets that are also available as cut pieces or in sheet format is recommended.

Frequently asked questions about SBR rubber sheets

For which applications is SBR particularly suitable? SBR rubber sheets are suitable for mechanically stressed applications in a dry environment. Typical fields of application lie in mechanical engineering, plant construction and in protective and backing solutions.

Which application limits must be taken into account with SBR? The material is designed for moderate temperatures and standardised ambient conditions. For increased requirements for weather or media resistance, a comparison with other rubber sheets is advisable.

Are there alternatives to SBR for special requirements? For applications with permanent weathering or contact with media, specialised elastomers are used. A frequently chosen alternative is EPDM, which is designed for outdoor areas.

How is the suitable hardness chosen? The choice of hardness depends on the desired damping and the load that occurs. Softer grades are suitable for vibration-damping applications, harder variants for dimensionally stable constructions.

Are individual cut pieces possible? SBR rubber sheets can be cut to size and adapted to specific installation situations. This supports efficient further processing and precisely fitting assembly.
