Pneumatic seals are made up of different raw materials and it comes in different types. It is in high demand with pneumatic seals suppliers in cylinders and Valves as it functions under low pressures. It is capable of high operating speeds, low friction and long service life. Overall it can handle almost any kind of pressure.
What are the different materials used in pneumatic seals?
The following are the raw materials used for the purpose of making hydraulic and pneumatic seals:
- ethylene acrylic.
- natural rubber.
- Fluoro silicon.
- stainless steel
- sintered bronze
- cast iron.
The reliability and service life of a pneumatic seal is possible only with good raw material used as well as the top-notch quality. Good material used in pneumatic seals provided by pneumatic seals suppliers prevents wear and Tear, scratches, cracks, and damage to the seal.
- Polyurethane materials have high durability excellent elasticity, High resistance, high Tear resistance, abrasion resistance, resistance against oil and Chemicals. The standard polyurethane material is made use of in Pistons, seals, rod seals, scrapers and questioning skills.
- The combination of polyurethane in metals and stainless steel is in highly used in scrapers and rod seals.
- Polyurethane combined with high molecular weight can function efficiently and reliability in temperature that ranges from minus 30 degree Celsius to + 80 degree Celsius. It has a wide range of applications in Piston seals, slide rings, rod seals and more.
- NBR metal combination is suitable for complete piston applicability, whereas just plain NBR is used in O ring energizers.
- Rod pneumatic seals:
The rod pneumatic seals are made up of metal which gives it is tough tensile strength and reliability. It has the ability to withstand fluid temperatures and highest pressure.
The Piston pneumatic seals:
The Piston pneumatic seals are mostly made up of polyurethane material. While in some cases it is made up of fabric reinforced rubber which makes it strong, tough, durable and slightly elastic in nature.
The wiper pneumatic seal:
There are different types of wiper pneumatic seal. Each of which is made up of different materials or a combination of materials that makes it efficient and reliable to use. Some of these pneumatic seals are made up of metal while others are made up of a combination of metals and compounds.
