High temperature resistant foamed silicone strip manufacturers

Types and uses of door and window sealing strips of high temperature resistant foamed silicone strip manufacturers Introduction: When we install doors and windows in life, there will always be certain gaps, which cause the doors and windows to close tightly. The door and window sealing strips are used 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 here. Door and window sealing strips can be divided into major categories in use: glass sealing strips, door leaf and door cover sealing strips and wool strips. The glass sealing strip is used to seal the gap between the glass 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 door. It is said that in the installation process of various doors and windows, the sealing strip is indispensable. It is used to maintain the door, window glass, front and rear windows, triangular windows and other parts of the body. Its better maintenance ensures safe and comfortable driving. However, few car owners pay attention to its maintenance, but in fact its maintenance is very It’s important because once it’s aging and damaged, it will cause rain leaks in the cabin and increase the wind noise of the car. Rain leaks can easily corrode the body. We can keep the car shelter from wind, rain, dust and heat by maintaining it. , Sound insulation effect, and when the body is shaken and distorted, it also plays a role in buffering, absorbing shock and retaining glass. It also plays a decorative role on the edge of the door and window junction, so the owner must maintain it frequently. Commonly used weather sealing strips include door frame sealing strips, luggage compartment sealing strips, engine box cover strips, etc. Commonly used general sealing strips include front and rear window sealing strips, corner window sealing strips, inner and outer strips, etc. The unique formula design makes EPDM The rubber sealing strip has excellent anti-aging, high and low temperature resistance and chemical resistance properties, good elasticity and resistance to compression deformation, long-term use will not crack or deform, and it can be between -50 degrees and 120 degrees. Maintain its original high sealing performance. The surface of the silicone rubber sealing strip is very flat. When observing its surface, we will find that its surface has a very uniform foaming density and also has good resilience performance. The choice of sealing material determines In order to have long-term flexibility and elasticity, through formula adjustment, the softness of the sealant after drying is improved, so that a good sealing layer is formed between the sheet metal and the rubber strip. The unique high elasticity of butyl rubber ensures the sealing The glue is easy to peel from the metal sheet without contaminating the sheet metal. The sealing strip plays a role of sealing and waterproofing in plastic steel doors and windows, aluminum alloy doors and windows, and wooden doors and windows. Sealing strips have very high requirements for materials. First, they must have strong stretchability and elasticity, as well as 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. The top is generally used to install on the sash of the push-type door and window to seal the gap between the frame and the sash. The specifications of the tops can largely affect the watertight performance of doors and windows, as well as the opening and closing of doors and windows. If the size of the top is too large, or the vertical hair is too high, it will be very difficult to assemble, and after the assembly is completed, the resistance of the doors and windows will increase when they move. If the fire size is too small, or the vertical hair is too low, the door and window are prone to bracket phenomenon, which reduces the airtightness of the door and window. 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 hairs 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. High temperature resistant foamed silicone strip manufacturers are still in use by a small number of door and window companies that are in low-level price competition. Middle and high-end PVC strips can reach standard indicators and have a relatively long service life. 5. Because of their excellent physical and mechanical properties, they often It is used to manufacture airplanes, cars, trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat-breaking windows, sealing parts and diving products, high-pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industries, Agricultural sealing parts, 8℃, EPDM rubber has excellent UV resistance, weather resistance, heat aging resistance, low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical insulation and Elasticity and other physical and mechanical properties, 2. The semi-finished rubber sealing strip extruded by the vulcanization cold feed extruder is vulcanized by continuous vulcanization process. The vulcanization methods include microwave vulcanization, shear head vulcanization, salt bath vulcanization and fluidized bed vulcanization (also It is called vulcanized bed vulcanization, and the heating medium is 0. What is it? The coated sealing strip is composed of four kinds of materials with excellent texture. The tough outer skin layer not only provides the basic quality guarantee for the coated sealing strip. , And beautiful and generous, it is a perfect companion for modern home doors and windows; thermosetting core, the main component is PU, which is the main material of the coated sealing strip, its super plasticity and our company's excellent technology can meet the requirements of different door and window manufacturers. demand
The manufacture marketing game of rubber seal strip suppliers is changing with each innovation, and businesses of all products need to be ready to pounce.
