SRBF Gaskets and Seals

SRBF stands for Synthetic Resin Bonded Fabric. It is a laminated engineering material typically manufactured using layers of cotton fabric impregnated and bonded with a phenolic resin.

SRBF is typically manufactured using layers of cotton fabric impregnated and bonded with a phenolic resin.

The resulting laminate combines the reinforcement provided by the fabric with the rigidity and stability of the resin system. Different grades are available for different mechanical and electrical requirements.

SRBF offers a useful combination of mechanical strength, rigidity, wear resistance and electrical insulation.

These properties make it particularly suitable for accurately manufactured gaskets, interfaces and separators where a tough non-metallic component is required rather than a soft, highly compressible seal.

Yes. SRBF can provide good electrical insulating properties and is commonly used within electrical and electro-mechanical equipment.

Suitability depends upon the particular SRBF grade, thickness, voltage, moisture exposure and operating conditions.

Yes. Good wear resistance is one of the useful characteristics of SRBF.

Its fabric-reinforced laminated construction makes it suitable for components exposed to mechanical contact and wear, including certain bearing, thrust and interface applications.

SRBF materials can typically operate at temperatures up to approximately +115°C to +120°C, depending upon the particular grade and application.

Mechanical loading, electrical requirements and environmental conditions should also be considered where components are used continuously at elevated temperatures.

SRBF is relatively rigid and has much less compressibility than elastomeric materials such as EPDM, nitrile or silicone rubber.

It is therefore generally more suitable for precision gaskets, insulating interfaces, mechanical separators and wear-resistant components than for applications requiring substantial compression to create a pressure-tight seal.

Moisture performance depends upon the particular SRBF grade and operating conditions.

Although suitable grades can perform well in many industrial environments, SRBF is a fabric-reinforced resin laminate and moisture exposure should be considered where dimensional or electrical performance is critical.

SRBF can be suitable for certain marine and wet-environment applications where its strength, electrical insulation or wear resistance provides an advantage.

The particular grade and level of moisture exposure should be considered before material selection, especially where the component performs a critical electrical or dimensional function.

SRBF is Synthetic Resin Bonded Fabric, while SRBP is Synthetic Resin Bonded Paper.

SRBF generally offers greater toughness, mechanical strength and wear resistance because of its fabric reinforcement, while SRBP can provide a cost-effective material for electrical insulation and lighter-duty applications.

SRBF is a rigid fabric-reinforced phenolic laminate designed to provide good mechanical strength, wear resistance and electrical insulation.

Pressphan is a lighter cellulose-based electrical insulation material generally used for thin barriers, separators and electrical insulating components. SRBF is therefore normally better suited where greater mechanical strength and rigidity are required.

Both SRBF and nylon can provide useful mechanical strength and electrical insulating properties.

SRBF provides a rigid laminated structure with good wear characteristics, while nylon is a thermoplastic offering excellent toughness and greater flexibility. The most appropriate material depends upon the mechanical, electrical and environmental requirements of the application.

Yes. Bluemay Weston manufactures bespoke SRBF gaskets and sealing components to customer drawings, dimensions, samples and specifications.

Components can be produced in simple circular and rectangular formats as well as complex profiles incorporating apertures, fixing holes, slots and other features.

Bluemay Weston manufactures SRBF gaskets and sealing components from sheet material using precision punching and water jet cutting techniques.

Punching provides an efficient manufacturing method for suitable repeat production quantities, whilst water jet cutting is particularly useful for prototypes, lower-volume production, larger components and complex profiles where dedicated tooling may not be appropriate.

Bluemay Weston can manufacture SRBF gaskets and sealing components in quantities ranging from prototypes and small development batches through to high-volume production runs of many thousands or millions of components, depending on component size, material specification and customer requirements.
