What is an EPDM seal? As this thing is not concerned about the book club is likely not very understanding. In fact, EPDM means EPDM. To put it bluntly, EPDM sealing strip isEPDM sealing stripMeaning. This sealing strip is used in the production of microwave vulcanization molding technology, to promote the surface of such products smooth, and has good toughness, deformation resistance, weather aging resistance, resistance to active oxygen, solvent corrosion resistance, and several other excellent quality in one.

Said so much, that it has what kind of characteristics?, this kind of product has excellent aging resistance: it means that it can resist long-term cold, hot, dry and wet cold and other harsh natural environment, and has excellent resistance to rain, snow and water corrosion, than the general seal sealant, it has a longer service life.

Second, high temperature aging resistance:EPDM sealing stripHas a strong resistance to high temperature gas aging. It can be used for a long time from 100-120 ℃, and can always maintain reasonable process performance at 140-150 ℃, and bear the high temperature of 230-260 ℃ in a short time.

Third, O3 resistance: EPDM is also known as "crack-free plastic", which is especially suitable for various urban construction with different air indexes. In this way, it can show the advantages of your products.

Fourth, anti-ultraviolet: it can provide good ecological environment protection for residents of multi-storey buildings. EPDM sealing strip can withstand 60 ~ 150kV working voltage, with electrical crack resistance, arc resistance, corona resistance and other characteristics. In addition, it also has ultra-low temperature elasticity, and its Rashin level can reach 100MPa when the temperature is -58.8 ℃.

Fifth,EPDM sealing stripOther excellent physical and physical properties: EPDM sealing strips are often used to seal high and low voltage switch cabinets, aluminum alloy profile heat insulation windows, curtain walls, airports, trains, passenger cars, vehicles, ships, deep diving products, etc. They can also be used on moisture-proof parts such as tunnel construction, viaduct connectors, high-pressure steam plastic hoses, and other industrial and agricultural seals.

　　EPDM sealing stripCan be widely used in shipping containers, mechanical equipment products, electrical products, household appliances, construction machinery and equipment, metal curtain walls, aluminum doors and windows, network cabinets, furniture, wooden doors and windows, electric control cabinets, machinery and equipment, and other industrial fields.

So how to distinguish the good and bad EPDM sealing strip? First can refer to its color, many counterfeit poor quality products in the application of low-end fake plastic, resulting in the production of the product color is generally particularly dim, the purpose is to deceive professional people, so that they can not distinguish the good and bad products at a glance. Before the product leaves the factory, this kind of unscrupulous merchant should carry out secondary processing on it with gray-black oil to brighten it and make it look black and bright. However, the good quality EPDM sealing strip of the plastic color authentic, the color is slightly heavier, and not very soft color or gray black.

You can smell the smell of EPDM sealing strip. Because the plastic contains cyclohexanol, the plastic has a choking smell that ordinary people feel. However, EPDM is a high polymer of butadiene and PE, which is a high filling raw material. Therefore, according to the vulcanized rubber-filled EPDM plastic does not have the spicy taste of ordinary rubber, followed by a fragrant taste. Therefore, as long as customers pay attention, they can naturally identify good products.
