Vulcanized O Rings
An o-ring is a round, mechanical gasket designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
Product Details
Vulcanized O Rings( accept OEM , according to your drawing)
BR(nitrile butadiene rubber)
The service temperature can be designed from -55 C to 100 C or up to 130 C
*Application
NBR compounds have excellent resistance to abrasion, non-polar oils and solvent, water and permeation (higher acrylonitrile content will be better). NBR also can be used in conditions of dilute acids, alkalis and salt solution at low temperatures
Silicone Rubber (Q, MQ, VMQ, PVMQ)
The service temperatures are from -60 C to 225 C. Some special types can be used in extreme temperature up to 300 C and down to -100 C.
*Application
Silicone rubber performs well under environmental and temperature extremes. It is usually applied in automotive and aerospace industries where flexibility and longevity are important. It is also a suitable material for parts that need FDA approval for food handling equipment and appliances.
PU (Polyurethane)
*Service Temperature
-45 to 120 °C
PU displays higher mechanical strength, high abrasion, wear and extrusion resistance, high pressure load capacity, as well as a high tear and elongation at break resistance.
PU is suitablefor for application in mineral oils and greases, hydraulic oils, silicone oils and greases, highly non-flammable hydraulic fluids HFA and HFB and water uo to 50℃.
PTFE O-Rings
Temperature range of -100°F to +400°F (-73°C to 204°C).
PTFE is the common sealing material used for making wear ring, backing-up ring, o ring, gasket, etc
Ethylene Propylene Rubber (EPM, EPDM)
*Service Temperature
For EPDM the service temperature can be designed from -55 C to 125 C or up to 150 C (for peroxide cured systems).
*Application
In phosphate-ester based hydraulic fluids and glycol based brake fluids systems Ethylene Propylene Rubber is good choice for sealing parts. EPDM is also is usually used in hot water or steam applications up to 150 C.
