Silicone strip HL75A, and at a high temperature of 120℃, the weather resistance of the sealing strip is still good, maintaining elastic properties, shape and function are not affected, low temperature elasticity, the temperature when the tensile capacity reaches 100MPa is -58, neoprene Sealing strip characteristics: Compared with other special rubbers, the individual performance is worse, but the overall performance balance is good, with excellent weather resistance, ozone resistance, heat aging resistance, oil and solvent resistance, and good chemical resistance. Excellent flame resistance and good adhesion. Introduction to electrical cabinet door self-adhesive sealing strips are made of three types of self-adhesive sealing strips with good elasticity and resistance to compression deformation, resistance to aging, ozone, and chemical effects, and a wide operating temperature range (-40°C to +120°C). Ethylene propylene rubber (EPDM) rubber is foamed and densely compounded. It contains unique metal clamps and tongue buckles, which is strong and durable. It plays a key role in various electrical cabinets. The good air-tightness and water-tightness of silicone strip
HL75A can realize the green and energy-saving of the building, prevent the conduction of heat, 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 chaotic world. Give you a quiet and comfortable life, here, we have a covered seal, which can meet the use of people of all ages, from the moment you are born, with you throughout your life! Choosing a covered seal, choosing a quiet life, happiness is so simple! . There is no obvious change in the physical properties of silicone rubber at -50°C. Fifth, depending on the specific gravity, how many meters can be produced per kilogram, the PVC sealing strip with heavy calcium added, you can stretch it back and forth several times by hand, and a small amount of white powder will appear on the surface. The density of PVC sealing strips should be 1,4-1,6. Silicone rubber sealing strips should be filled with nano-scale silica as a filling and reinforcing effect. The texture is light and the density ratio is between 1,1-1,25. The material rate is 20% higher than that of PVC sealing strips. The skeleton sealing strip is co-extruded from dense rubber, foam rubber and steel wire/steel sheet. Also known as EPDM sealing strip (EPDM)-suitable for the special environment of -40℃ -+160℃, it has superior anti-ozone characteristics, anti-ultraviolet characteristics, resistance to chemical solvents, and various physical and chemical performance indicators far exceed Similar products. According to the sealing characteristics, the silicone rubber strip HL75A automobile sealing strip can be divided into weather sealing strip (WEATHERSTRIP) and general sealing strip (SEALING). Among them, the weather sealing strip has a hollow sponge bubble tube, which has better temperature and humidity maintenance function. The usual maintenance process includes the following items. First, the detergent must be cleaned. After the cleaning is not done, a layer of protective agent must be applied. This can prevent aging and prevent dust. 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. 3. Because EPDM has excellent resistance Ozone, also known as 'crack-free rubberIt provides environmental protection for residents of high-rise buildings; it can withstand voltages of 60~150KV, corona resistance, electric crack resistance, and arc resistance, and it is also very good. According to the cross-sectional shape, it can be divided into solid core products (round, square, flat cross-sectional shape), hollow products and metal rubber composite products. Among them, metal rubber composite sealing strips account for more than 60%. For rubber sealing strips The cross-section design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should contact the glass from both sides of the window glass with the same and appropriate force. According to the sealing characteristics, they can be divided into weather seals. Strip (WEATHERSTRIP) and general sealing strip (SEALING). It is widely used in the fields of box sealing and building sealing. The cold resistance, heat resistance, foaming, solid, and special properties of different application fields developed and designed by our company can meet the application needs. Installation method of inlaid wooden door sealing strip ：Because the width of the saw blade or grooving knife used by each manufacturer when grooving is different, there are usually 4mm, 3mm, 2.5mm, 2.0mm, and most of them are 3mm, which is used in the purchase of seals. Be optimistic about the article.
custom sealing strip are required in the manufacture of almost every product and custom sealing strip rubber seal strip suppliers
