Will it affect your daily mood and mood after a long time? New PU hair The foam sealing strip has super elastic resilience, no deformation, odorless and environmental protection, and the sound insulation and anti-collision effect is more obvious, which is worth having. 5) EPDM rubber material 40°F-248°f (-40°C-120°C) , Nitrile-butadiene 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: In our daily life, when we install 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 used to eliminate these gaps. But there are many types of door and window sealing strips, and their uses It’s also different. I’m here to sort out some information about the types of door and window sealing strips for everyone. The use of door and window sealing strips can be divided into broad categories: glass sealing strips, door leaf and door cover sealing strips and wool strips. Among them, glass sealing strips are 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 leaf. In the installation process of various doors and windows Among them, 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. The sealing strip has high requirements for materials, and must have a strong tensile ability first And elasticity, as well as better 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. 8℃ ,, Disadvantages: Generally, it has a large expansion in mineral oil and lubricating oil, and is generally a dark-colored product. Scope of application: Use temperature range -60-150 ℃, suitable for high temperature and cold coastal areas with strong ultraviolet radiation and middle and high-rise buildings. It has a wide range of applications and excellent comprehensive performance. It has been recognized by the domestic door and window industry. Disadvantages: poor storage stability, hardening during storage, poor cold resistance, high relative density, and generally black products. For this reason, very early The standard GB12002-89 'Sealing Strips for Plastic Doors and Windows' was formulated to standardize the production and inspection of sealing strips. However, the quality and price of rubber and plastic sealing strips for doors and windows in the current building materials market are very confusing. Four composite sealing strips- —Our company takes the lead in developing and producing composite sealing strips composed of 4 kinds of rubber materials in China, and a thin protective layer of glue is coated on the surface of cotton rubber (bubble tube) to further improve the sealing performance. Service life. Tops are generally used to install on the sashes of push-type doors and windows 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, and also affect the performance of doors and windows. Switch. 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 Is the vertical hair too low? Brackets are prone to occur, reducing 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 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. It is suitable for all kinds of doors, windows, etc. 2. Cabinet sealing strips have developed their own characteristics based on the use of electrical cabinets and based on 20 years of experience in the research and development of sealing strips, which have good sealing performance. , Waterproof, fireproof, insect-proof, windproof, light-proof, anti-collision and long service life, etc. 1. Three composite steel framework, not easy to deform and shrink, firm assembly, good sealing 2. Sealing strips for doors, windows and curtain walls, products It has good elasticity, resistance to migration, and can effectively block noise, dust, and weather. 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. Good airtightness and watertightness can realize the green and energy-saving of the building, prevent heat conduction, and realize the energy-saving and thermal insulation function of warm in winter and cool in summer. The coated sealing strip keeps you away from the hustle and bustle of the world and gives you a A quiet and comfortable life, here, we have a covered sealing strip, which can meet the use of people of all ages, from the moment you are born, to accompany you throughout your life!

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.
