Shore Hardness of Silicone Sealing Strip

by:Kenna     2021-06-30
The Shore hardness of silicone sealant strip is very simple in construction, and there is no complicated process. This is also a must-have for an EPDM sealing strip. Many people are concerned about the EPDM sealing strip. The product is not well understood, let alone the characteristics and advantages of the product. First of all, the weather resistance of the product is very good. It can be used in severe cold and hot environments, dry and humid environments for a long time, and it can also have a Good corrosion resistance, these advantages can extend the service life of the product. Types and uses of door and window sealing strips Introduction: When we install doors and windows in our lives, there will always be certain gaps, which will cause the doors and windows to close tightly. The role of door and window sealing strips is 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. 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 high requirements for materials. First of all, 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. Third, the structure of good water absorption is very characteristic. It adopts the structure of independent bubbles. Therefore, the water absorption performance of the product is very good, which will achieve the effect of moisture resistance. This product has many advantages. Not only is the transparent effect good, but the appearance of the product is also very smooth. It is a very soft and elastic product. Moreover, this product has no odor and has good high temperature and low temperature resistance. The use of this product is not prone to aging and deformation. Then, what are the characteristics and uses of rubber sealing strips? Because PVC products contain halogens and heavy metals in stabilizers, they are not conducive to environmental protection. Therefore, developed foreign countries and domestic Beijing and coastal cities have eliminated or restricted the use of PVC strips, low temperature elasticity, and the temperature when the tensile capacity reaches 100MPa is -58 , EPDM rubber is a copolymer of ethylene, propylene and a small amount of third monomer non-conjugated diene, the international name: EthyienePropyeneDieneMethyiene is referred to as EPDM. The wool strip 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 greatly 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 it is assembled, the resistance of doors and windows will increase when they move. 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. It is divided into self-adhesive type and card slot type. It is used in different doors and windows. It is more convenient and feasible in operation and installation. It does not react with any paint or cleaning agent. Customers do not need to worry about the integrity and beauty of doors and windows. Pieces: elastic pan seat and key or fixing screw 1. Use your nose to smell whether there is any peculiar smell. Normal PVC sealing strips will have a pungent smell, normal silicone rubber sealing strips will only have a little mellow smell , The smell is so small that it can hardly smell. 3. Among them, the weather sealing strip has a hollow sponge tube, which has a good temperature and humidity maintenance function. The commonly used weather sealing strips include door frame sealing strips, trunk sealing strips, engine box cover strips, etc., and common general sealing strips have front and back Windshield sealing strips and corner window sealing strips, inner and outer strips, etc., 4, 5, according to material types, can be divided into rubber sealing strips; plastic sealing strips; thermoplastic elastomer sealing strips, special function classification, some sealing strips have electronic Intelligent functions, such as anti-pinch seals, etc. High-quality products will improve the overall style and performance of the door in terms of appearance, internal quality, or later use. Wrapped seals are a modern development trend. Where can wrap seals be used? Wooden windows, aluminum clad wood, aluminum alloy doors and windows, wooden doors, wood-plastic doors, ecological doors, log doors, solid wood doors, painted doors, oak doors, composite doors, suit doors, security doors, sliding doors, wardrobe doors, cabinet doors, Bronze doors, cast aluminum doors, plastic steel doors and windows, etc. The main function of the silicone rubber sealing tape Shore hardness door and window is to seal, how to strengthen the sealing performance, then the sealing strip plays a very key role. The common sealing strips on the market are generally made of pvc material. The quality of the sealing strips mainly depends on the pros and cons of the plasticizers added. With the increase in the price of various chemical fields, the price of the sealing strips is constantly increasing. rise.
