The method of distinguishing EPDM sealing strip is as follows:
1. Look at its color
Look at the color, that is, carefully check the color of the rubber body. Many counterfeit goods use low-end and inferior rubber, so the color of the produced spheres is usually particularly dim to prevent experienced people from seeing it at a glance. Most of them polish it with black shoe polish before leaving the factory to make it look black and bright. However, the rubber joint produced by real EPDM has pure color and slightly heavier color. Not particularly bright or dark
2. Smell
Because rubber is rich in olefins, it has a pungent smell that normal people feel. However, EPDM is a polymer of ethylene and propylene, which is a high filling material. Therefore, the ethylene propylene diene monomer filled by vulcanization does not have the pungent flavor of ordinary rubber, but replaces the aromatic flavor. Therefore, as long as users pay attention, it is not difficult to distinguish really good goods
3. Feel
Authentic EPDM rubber is expensive. Therefore, the produced rubber soft joint is particularly smooth when contacting, while the general rubber feels much worse and will contact rough skin.
EPDM sealing strips are widely used in containers, building curtain walls, electrical appliances, doors and windows, household appliances, mechanical products, cabinets, electrical cabinets, furniture, wooden doors and windows, engineering machinery, equipment, engineering construction and other production fields.
