[Sell] PU 90 O Ring View details for: PU 90 O Ring
PU 90 O Ring Polyurethane natural rubber (AU) Polyurethane / AU O-rings are characterised by especially high efficiency. Polyurethane / AU O-rings have very high mechanical values including resistance to friction and tearing, very good rebound properties and high gas proof properties. Resistance to fuel, and to many other common technical oils, especially those with higher aromatics content, is excellent. Thanks to its resistance to high temperatures (up to +125 C) and good low-temperature flexibility (down to -30 C) and outstanding resistance to oxygen and ozone, an O-ring seal of polyurethane natural rubber can be expected to last a long time.

It can be applied to electronic components for insulation, waterproofing, fixed and flame retardant. It mainly applied in electronic components surface with materials of PC(Poly-carbonate)、PP、ABS、PVC, etc. and metal materials.
2. Typical Application of Electronic Potting Silicone Rubber
HY-9055 electronic potting silicone rubber could be applied to
- high powered electronics,
- DC/DC module and circuit board which requires heat dissipation and high temperature resistance.
-It can be broadly used for LED screen, Wind Power Generator, PCB substrate, etc.
3. Technical Guidelines of of Electronic Potting Silicone Rubber
a, Pls put part A and part B in separate container and stir evenly before mixing the two part together.
b, Mixing Ratio: part A: part B = 1:1
c, Deaeration the mixture in vacuum pump under 0.08 MPa for 3-5 minutes.Then the mixture could be used for pouring.
Note: The thickness of the silicone affects the curing time. If the silicone used is a little thick,then the curing time will be a little longer.The temperature also affects the curing time.When in lower temperature, we suggest customers appropriately heat the mixture to accelerate vulcanization. With temperature of 80~100℃, the silicone will cure in 15 minutes; while in 25℃ room temperature, the silicone will cure around 8 hours.
