Ethylene-propylene diene rubber foam sealing strip function:

1. Foamed epdm foam sealing strip packaging materials (cushioning materials for transportation of precision machinery, medical appliances, furniture, glass, etc., protective cushioning materials for small electrical appliances, etc.).

2. Civil engineering and construction (large slab caulking materials for residential buildings, sealing materials for doors and Windows for residential buildings, gasket materials for concrete to prevent shrinkage, open channel caulking materials, various civil and architectural caulking materials, etc.).

3. Vehicles and ships (door sealing materials, baggage storage sealing materials, engine hood cushioning pads, various pipe sealing materials, lamp sealing materials, engine anti-vibration materials, instrument cushioning and sealing materials, etc.).

4, insulation, insulation (cooler and air conditioner use insulation sealing materials, refrigerator and refrigerator insulation sealing materials, etc.).

5, foaming epdm foam seal strip sound insulation, moisture-proof (various mechanical equipment noise proof sealing materials, residential sound insulation wall sealing materials, various electrical appliances waterproof moisture-proof sealing materials, various mechanical equipment moisture-proof sealing materials, etc.).

To understand the role of ethylene-propylene diene seal, then to understand the identification of ethylene-propylene diene seal quality method, analysis as follows:

1, the taste of the rubber will have a certain smell, especially to flush the nose, the normal rubber seal will only have the taste of plastic, good quality is the base will not smell the taste.

2, the appearance of the seal is ten points rough appearance, feel is also very hard, there is no tension. On the other hand, it is shiny, soft and tensile.

3, the specific gravity of the seal is particularly heavy, that is, due to the production of the filler when the choice of heavy calcium or talc powder and other filling material, so will add the specific gravity of the seal, and a good seal is directly choose light calcium carbonate to fill the material. Install door window seal strip to profile on or it is to wrap directly to plastic profile on the place that puts high temperature to undertake insolation, the rubber strip of the second is to pass the contact surface of high temperature, profile directly to be able to change color, the surface also can touch dust, and appear send yellow and ooze the circumstance of oil. Smell with the nose is what taste, epdm rubber strip has the taste of rubber, although he is synthetic rubber but it is rubber, so also will have the taste of rubber, rubber plastic is the taste of plastic, the industry said rubber plastic is modified PVC, this is from the taste of separation. With the fire a rubber, rubber seal rubber and epdm seal is the difference between the rubber burning is black ash, there will be some viscosity, with the hand pinch will pull, and epdm rubber burning is white ash, with the hand a pinch into the black side. And for a long time in ultraviolet and other climatic conditions, the physical properties of the only small changes.
