Wespo EN 45545 Standard Rail Component
WESPO Silicone EN45545-2 R22/R23
By 2050, the growing world’s population will reach 10 billion people, with the great majority living in or near cities. Railways will become an important constituent in the transportation mix of trains, trams and subways, both for urban mobility and intercity travel. Rail system managers and train operators are developing efficient, safe, and cost-effective railway technologies. In Europe, the new Rolling stocks standard in place since 2018, EN 45545, reinforces the need for high-temperature and fire-resistant materials. In addition, railway parts such as profiles, panels and gangways and bellows must present high mechanical performances to pass the stringent dynamic.
The development of silicone compound WS3044/F44/M makes a considerable achievement for the wespo as it was made by our in-house chemist team and independently tested by a recognised third-party test house. ( report available).The wespo silicone elastomer is fully EN 45545 certified, a European Standard that defines the fire safety testing for materials and components installed on railway vehicles. The challenge was to formulate a compound that demonstrated low flammability, smoke emission and toxicity. The EN 45545 approved It is suitable for use in any enclosed environment where fire safety is a primary concern.
The elastomer is currently available as a rolled sheeting and extruded profile, making it ideal for gasket cutting and custom seals. The Wespo team are delighted to seize this opportunity and serve the transportation sector as a trusted EN 45545 manufacturer and supplier.
Wespo Compliance Silicone Rubber that complies EN45545-2 R22/R23 (The European railway standard for fire safety) products available in any form it conforms to “HL (Hazard Level)-3”, which is said to be the most stringent EN45545-2 R22/R23 (The European railway standard for fire safety)
It has excellent flame retardancy and low smoke generation and since it is a product whose conformity has been confirmed by a test organization that has acquired ISO / IEC17025 certification, it is easy to use as a gasket or packing or sealing for railway vehicles or in a building were safety is the main concern
leading manufacturers of fabric inflatable seal
Today western polyrub stand out as leading manufacturers of fabric inflatable seal who make seals with hand built and fully moulded with fabric reinforcement inside make seal so tough that can withstand pressure up to 50 Kgcm2 Fabric Reinforced Rubber Seals Are Effective Where Moderate- To High-pressure Is Applied(we make seal up to 50bar bursting pressure ) , Such As In Heavy Industrial, Environmental, Technical And Laboratory Environments,marine,nuclear Region A Variety Of Reinforcing Fabrics Are Available And Determined By Factors Such As Temperature And Pressure.
Fabric inflatable seal moulded
Wespo also provide fabric inflatable seal moulded with rubber nozzle for flexibility and longer life if clients demand Western Polyrub Offers Technical Guidance To Determine The Appropriate Design, Manufacturing And Material Composition. The Fabric Inflatable Must Withstand Environmental Factors And Perform Using Air Or Gas Controlled Mechanisms Under Pressure. The Environment And Structure Will Affect The Choice
OFFSHORE APPLICATION
Western polyrub has developed technology to used fabric reinforced inflatable seal in a number of critical applications including offshore production, storage and offloading (FPSO); anchoring drill rigs to the seabed; gas loading systems; pipeline welding; and watertight doors and panel High -pressure inflatable seals are designed to fit in metal retaining grooves, allowing axial, external radial and internal radial expansion, These seals typically can withstand pressures of up to 8 bar, and are suitable for sealing clearances from 2-10mm.
