Beldam Crossley has a proud history, the origins of which date back to 1876. Over the many years since, we have achieved an unrivalled reputation for providing advanced sealing, bearing and polymer-based products. This experience and expertise mean we are able to offer safe and highly reliable solutions for use in the most arduous of conditions.
Beldam Crossley are experts in creating bespoke PTFE ‘recipes’, by mixing PTFE with carefully tested ingredients commonly known as ‘fillers’, we can enhance overall properties such as strength, colour and even conductivity!
Problem: Many materials degrade when exposed to aggressive chemicals, leading to frequent replacements.
Solution: PTFE is highly resistant to almost all chemicals, making it ideal for seals and gaskets in chemical processing, pharmaceuticals, and oil & gas industries.
Problem: Standard materials fail in extreme temperatures, causing leaks and operational hazards.
Solution: PTFE withstands temperatures from -200°C to +260°C, ensuring long-term performance in high-heat applications like aerospace and automotive industries.
Problem: High friction leads to wear and tear in dynamic applications, reducing efficiency.
Solution: PTFE has a low coefficient of friction, providing smooth operation in seals, bearings, and bellows, reducing maintenance costs.
Problem: Electrical arcing and poor insulation can cause short circuits and failures.
Solution: PTFE has excellent dielectric properties, making it ideal for gaskets and seals in electrical applications.
Machined components made from PTFE (Polytetrafluoroethylene) have several unique benefits over other material including rubber and polymers including nylons, that make it a highly desirable material for applications in a range of industries. Proven properties making PTFE the preferred choice include:
Problem: Many materials absorb moisture, leading to swelling, reduced effectiveness, and mechanical failure.
Solution: PTFE is hydrophobic (does not absorb water), making it perfect for seals and gaskets in marine, chemical, and outdoor applications.
Problem: Traditional materials lose flexibility over time, leading to cracks and failure in bellows and expansion joints.
Solution: PTFE bellows offer high flexibility, fatigue resistance, and longevity, reducing failure rates in applications requiring movement and vibration absorption.
Problem: Gaskets and seals may fail under pressure when handling aggressive fluids and gases.
Solution: PTFE’s non-reactive nature ensures leak-proof sealing for acids, bases, and gases in industrial pipelines and processing plants.
Problem: Prolonged exposure to sunlight, ozone, and harsh weather conditions can degrade traditional materials.
Solution: PTFE is UV-resistant and weatherproof, ensuring durability in outdoor and aerospace applications.
Problem: Regular replacement of components leads to high maintenance costs and production downtime.
Solution: PTFE’s long service life, durability, and self-lubricating properties reduce the need for frequent replacements, increasing operational efficiency.
