What are the characteristics of the real EPDM sealant strip

The characteristics of EPDM sealant strip can be summarized as follows: 1. EPDM sealant strip has weather resistance, weather resistance refers to the characteristics of long-term resistance to cold, hot, boring and humid, excellent corrosion resistance to rain, snow and water, and can extend the service life of the rubber strip; 2. EPDM sealant strip has heat resistance and aging, heat resistance and aging refers to strong heat resistance to air aging, it can be used for a long time at 100-120 ℃, and can withstand high temperatures of 230-260 ℃ in a short time; 3. EPDM has excellent ozone resistance, also known as "crack-free rubber", especially

Changtu Changqi Sealing Products Factory: Selection of Metal Coating Material

According to different application environments, metal coated plates have the following choices in material use: rubber varieties: fluorine rubber, nitrile rubber, foamed rubber metal substrate: stainless steel, cold rolled steel, aluminum plate Changtu long steam sealing products are coated with very thin and strong rubber on both sides or one side of the metal plate, plus vulcanized metal sealing material, so that the material has good temperature resistance and durability, has a very low compression set. Compared with traditional non-metallic sealing materials, this material has a relatively long service life. Therefore, it is usually used in higher pressure, higher temperature, and sealing requirements.

Changtu Changqi Sealing Products Factory: Identification of EPDM Sealing Strip

The identification method of EPDM rubber sealing strip: 1. observe its color, that is, carefully inspect the color of the rubber body. many counterfeit goods use low-end and inferior rubber. in order to prevent it from being seen at a glance, most of them will take black shoe polish to polish it before leaving the factory to make it look black and bright. However, the rubber strip produced by the real EPDM rubber is pure in luster and slightly dark, not especially bright or especially dark. 2. Smell its smell, because the rubber contains alkene, so there is a pungent smell, but EPDM rubber not only does not have the pungent smell of ordinary rubber, but instead

Silicone rubber sealant strip with transparent, smooth appearance

Silicone rubber sealant strip has a transparent, smooth appearance, soft and elastic, non-toxic and tasteless. Silicone rubber sealing strip has excellent high temperature resistance (200-280 ℃) and low temperature resistance, good physiological stability, excellent small back deformation (200 ℃,48 hours not more than 50%), breakdown voltage (20-25KV/mm), ozone resistance and ultraviolet resistance, and is widely used in medical diversion, electronics, lighter tubes and ignition gun tubes, which is more than three times the service life of ordinary rubber seals. Silicone rubber strips have high resistivity and are resistant to preservation over a wide range of temperatures and frequencies.
