Materials That Are Suitable for Inflatable Seals
| Material | Temperature Range | Strengths | Limitations |
|---|---|---|---|
| EPDM | -50°C to 150°C | Excellent aging, ozone, weather resistance; Flexible at low temperatures | Poor resistance to petroleum oils, acids, and bases |
| Neoprene | -40°C to 125°C | Good weather and ozone resistance; Moderate oil resistance; Flame resistant | Not suitable for strong acids, esters, or gasoline |
| NBR | -40°C to 120°C | High resistance to oils and fuels; Good abrasion resistance | Poor resistance to ozone, sunlight, and weathering |
| HNBR | -40°C to 165°C | Exceptional oil/fuel resistance; Superior mechanical properties | Higher cost; Limited resistance to strong acids and bases |
| Natural Rubber (NR) | -50°C to 80°C | High resilience, flexibility; Good adhesion to metals | Poor resistance to oils, ozone, weathering; Limited temperature stability |
| Silicone (MVQ) | -60°C to 230°C | Excellent temperature resistance; Good weather and UV resistance | Poor resistance to oils, acids; Lower tensile strength |
| Fluorosilicone (FVMQ) | -60°C to 200°C | Excellent resistance to oils and solvents; Wide temperature range | Higher cost; Lower mechanical properties than silicone |
| FKM (Viton) | -20°C to 200°C | Superior chemical resistance; Excellent high-temp stability | Poor low-temperature performance; Higher cost |

Frequently Asked Questions
What is the ideal pressure required for operating inflatable seals?
Typically, 1-3 Bar pressure is sufficient for most inflatable seal sections. For applications requiring higher pressures, seals need to be specially designed. Western Rubbers has developed seals capable of withstanding pressures up to 30 Bar.
Do I need a fabric-reinforced seal?
For nominal pressure applications, non-reinforced seals are usually adequate and cost-effective. However, for pressure requirements exceeding 7-8 Bar, fabric-reinforced inflatable seals are recommended to ensure longer life and effective functionality.
What is the maximum temperature inflatable seals can withstand?
Inflatable seals can be manufactured to withstand temperatures up to 250°C (480°F).
What types of fabric reinforcement are available for inflatable seals?
Available fabric reinforcements include Kevlar, Nylon, Nomex, Polypropylene, and Dacron.
Does my inflatable seal require continuous air supply?
Inflatable seals can be designed for either continuous air supply or to function with a one-time fill, similar to a tire tube.
What should be the ideal inflation gap?
For optimal seal longevity, the inflation gap between the striking surface of the seal and the mating surface should be between 5-8 mm.
What is the maximum pressure inflatable seals can withstand?
Western Rubbers manufactures seals capable of withstanding pressures up to 30 Bar.
Do you provide design, development, and deployment services?
Yes, Western Rubbers offers comprehensive services, including design, development, and deployment, tailored to meet specific customer requirements.
