EPDM sealing strip, do you really understand?


EPDM sealing striphasGoodThe physical and mechanical properties of anti-ultraviolet, weather resistance, heat aging, low temperature resistance, ozone resistance, chemical medium resistance, water resistance, good electrical insulation and elasticity are copolymers of ethylene, propylene and a small amount of non-conjugated dienes as the third monomer.

EPDM sealing stripFeatures:

1,EPDM sealing striphasGoodWeather resistance, weather resistance refers to its long-term cold resistance, heat resistance, dry resistance, moisture resistance, rain, snow, water erosion has.GoodThe corrosion resistance of the rubber strip can completely extend the service life of the rubber strip.

2. Heat aging resistance refers to strong heat-resistant air aging resistance. EPDM sealing strips can be used for a long time at 100-120 degrees, can maintain effective physical properties for a long time at 140-150 degrees, and can withstand high temperatures of 230-260 degrees in a short time. Therefore, it can be used as a delay for urban buildings in case of sudden accidents.


3, EPDM rubber because of itsGoodOzone resistance, also known"Crack-free rubber", especially when it is applied to urban buildings with different atmospheric indexes and completely exposed to the air, will show the superiority of its products.

4. Anti-ultraviolet radiation, providing environmental protection for high-rise building residents; Can withstand 60 ~ 150KV voltage, resistant to electrical cracking, corona and arc; Low temperature elasticity, the temperature when the tensile capacity reaches 100MPa is -58.8 degrees.

5, because of itsGoodEPDM sealing strips are often used in the manufacture of airplanes, trains, automobiles, buses, ships, high and low voltage switchgear, diving products, aluminum alloy insulation windows, glass curtain walls, high pressure steam hoses, tunnels, Waterproof parts such as viaduct joints and other industrial and agricultural sealing parts.

EPDM sealing stripPerformance and use:

1. Low density and high filling. Ethylene-propylene rubber is a low-density rubber with a density of 0.87, which can be filled with a large amount of oil and filler. Therefore, the cost of rubber products can be reduced to make up for the high price of ethylene propylene rubber raw rubber. Moreover, for ethylene-propylene rubber with high Mooney value, the physical and mechanical energy drop after high filling is very small.

2. Anti-aging. EPDM sealing strip hasGoodWeather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil and room temperature mobility. Ethylene propylene rubber products can be found inLong-term use at 120 degrees, temporary or intermittent use at 150-200 degrees, adding an appropriate amount of antioxidants can increase the use temperature.

3. Water vapor resistance. EPDM sealing strip hasGoodThe steam resistance is estimated to be superior to its heat resistance. InAfter being placed in superheated steam at 230 degrees for nearly 100 hours, its appearance did not change. The appearance of silicone rubber, fluororubber, fluorosilicone rubber, nitrile rubber, butyl rubber, and natural rubber is significantly deteriorated after a short time under the same conditions.

4. Anti-overheating. Ethylene-propylene rubber has good heat resistance, but it is closely related to all vulcanization systems.

5. Electrical performance. EPDM sealing strip hasGoodElectrical insulation and corona resistance, electrical performance is better than or close to styrene butadiene rubber, chlorosulfonated polyethylene, polyethylene and cross-linked polyethylene.
