Is the silicone waterproof strip good? There will be a 'bump! Bump!...' impact sound when you close the door and cabinet door for countless times. Will it affect your mood and mood every day? The new PU foam sealing strip, It has super resilience, no deformation, odorless and environmental protection, sound insulation and anti-collision effect is more obvious, it is worth having, 5) EPDM rubber material 40°F-248°f (-40°C-120°C), nitrile-butyl Diene rubber material 40°F-248°f (-40°C-120°C), silicone rubber material 40°F-260°f (-40°C-126. Types and uses of door and window sealing strips. Introduction: We are in life When installing doors and windows, there will always be certain gaps, which cause the doors and windows to close tightly. The role of door and window sealing strips is to eliminate these gaps. However, there are many types of door and window sealing strips, and their uses are also different. I have compiled some relevant information about the types of door and window sealing strips for everyone. The use of door and window sealing strips can be divided into major categories: glass sealing strips, door leaf and door cover sealing strips and wool strips. Among them, glass sealing strips are used to seal glass The gap between the leaf and the frame The door leaf sealing strip is used to seal the gap between the door panel and the door frame, and the wool strip is mainly used to seal the gap between the frame and the leaf. In the installation process of various doors and windows, sealing Strips are indispensable. Sealing strips play a role in sealing and waterproofing plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. Sealing strips have high requirements for materials. First, they must have strong stretchability and elasticity, and Good temperature resistance and aging resistance. At the same time, in order to ensure the close contact between the sealing strip and the profile, the cross-sectional structure of the sealing strip must match the profile of the door and window, which is generally suitable for hanging windows and folding doors and windows. Nowadays, cars have also been It is very common and has become our main transportation tool. Its basic function can fill some gaps in the body, so that it can achieve good shock absorption and waterproof effects. Features: 1. EPDM has excellent weather resistance Resistance and weather resistance refer to long-term resistance to severe cold, heat, dryness, and humidity, excellent corrosion resistance to rain and snow, and can completely extend the service life of the rubber strip; 2. Heat aging resistance refers to It has strong resistance to heat-resistant air aging. It also has good dustproof, sound insulation and decorative effects, and it also protects the car body, effectively improving the comfort of the ride. The characteristics of the car sealing strip are -40 In the ℃ low temperature resistance test, the sealant strip does not become hard or brittle, and still maintains softness and good adhesion of the strip, showing excellent cold resistance. The performance characteristics of the EPDM seal strip: excellent comprehensive performance and outstanding Excellent ozone resistance, excellent weather resistance, good high temperature resistance, low temperature performance, outstanding chemical resistance, resistance to a variety of polar solutes, and low relative density. The wool strips are used to install on the fans of push-position doors and windows. Used to seal the gap between the frame and the fan. The specification of the top can greatly affect the watertight performance of doors and windows, and also affect the opening and closing of doors and windows. If the specification of the top is too large, or the vertical hair is too high, It will be very difficult during assembly, and after assembly, the doors and windows will be moving. When the resistance becomes larger. If the fire size is too small, or the vertical hair is too low, brackets are prone to occur in doors and windows, which reduces the airtightness of doors and windows. There are generally two types of tops that have undergone silicification treatment and those that have not been silicified. Generally, the treatment effect will be better. Quality tops have the following characteristics: there are no obvious defects in appearance, the surface is straight, the bottom plate and vertical hair are relatively smooth, there is no bending phenomenon, and there are no pits and other problems on the bottom plate, and it meets the size requirements. Second, high heat insulation. In the process of use, it has good heat insulation, which greatly reduces the thermal conductivity. Therefore, the heat insulation of this product is very good, which can effectively prevent the loss of temperature. 3. The demand for rubber sealing strips in the automobile industry is very large. Some electronic parts and electrical assembly parts are needed, such as the sealing of windshields and automobile windows, as well as the outer skin of high-voltage lines. There are spark plug protection covers and many other places. Uses are mainly used in the door frame, side windows, front and rear windshield, engine cover and trunk cover, which play the role of waterproof, dustproof, sound insulation, temperature insulation, shock absorption, and decoration. The unique formula design makes three Ethylene propylene rubber sealing strip has excellent anti-aging, high and low temperature resistance and chemical resistance performance, has good elasticity and resistance to compression deformation, and will not crack or deform after long-term use. It is between -50 degrees and 120 degrees. It can maintain its original high sealing performance. It can be used at 100-120℃ for a long time, and it can maintain effective physical properties for a long period of time at 140-150℃. It can withstand high temperature of 230-260℃ in a short time. It can be used in sudden accidents to urban buildings. To delay effect; coupled with the use of special formula, EPDM rubber feels similar at -50℃ to 150℃, which creates high efficiency work performance for installation on the production site
