Flame retardant and high temperature resistant silicone profiled strips

by:Kenna     2021-03-16
Flame-retardant and high-temperature resistant silica gel special-shaped strips, 8°C, Disadvantage: Generally, it has a large expansion in mineral oil and lubricating oil, and is generally a dark product. Application range: Use temperature range -60-150°C, suitable for high temperature and cold coastal Areas with strong ultraviolet radiation and medium and high-rise buildings are recognized by the domestic door and window industry for their wide application range and excellent comprehensive performance. Disadvantages: poor storage stability, hardening during storage, poor cold resistance, high relative density, and general It is a black product. 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. Flame-retardant and high-temperature resistant silicone profiled strips, metal rubber composite sealing strips account for more than 60%. For rubber sealing strips, the cross-sectional design is very important. The first is the shape and size of the sealing lip. The sealing lips on both sides should be the same , Appropriate force touches the glass from both sides of the car window glass, 3) It has an independent open-pore bubble structure, and the appearance of the special-made joint board is a honeycomb-shaped hole evenly distributed, and it can be tightly bonded with cement/sealant without beating. Integrate into one, adapt to changes in natural expansion and contraction, and enhance the effect of joint sealing, expansion and water stop. It is also called fireproof silicone sealing strip and fireproof self-extinguishing silicone sealing strip. It is famous for its good flame-retardant and self-extinguishing performance. The main process is to first use high-quality silicone raw materials to make a molded silicone strip through a large extruder. Then it must be made by high room temperature vulcanization and drying. Compared with ordinary silica gel strips, the high temperature resistant flame retardant silica gel strips are different in that it needs to add flame retardant powder to the formula. The silica strips made by doing so are super strong. The flame-retardant and fire-proof performance of the product has played a certain safety guarantee in the sealing of electronic appliances, so many people also call it a fire-proof sealing strip. 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. The sound insulation, heat preservation, airtightness, impact resistance and environmental protection characteristics of flame-retardant and high-temperature resistant silicone shaped strips have attracted more and more consumers’ attention. 'Functionality' has long been a function of German design. , Reasonable and reliable image, especially the harmony and unity of the whole product in terms of technology, function, logic and sense of order. 'The covered sealing strip structure makes the door leaf and the door cover tight and seamless, blocking sound penetration stronger, and has Strong resilience, sound insulation and environmental protection. The product is environmentally friendly, easy to construct, anti-seepage, anti-leakage, and good water-stop effect. 2) Corrosion resistance, aging resistance, high and low temperature resistance +80℃~-45℃, no flow, No deformation, no brittleness, long service life, thermoplastic EPDM rubber sealing strip This sealing strip is a new material developed on the basis of imported technology from abroad and domestic independent research and development in recent years. It is mainly used for automobile doors and windows. Sealing strips have been used in building door and window sealing strips in recent years. Its outstanding advantages are: ①The performance and service life are equivalent to those of vulcanized EPDM rubber sealing strips. Among them, classification according to the title of device parts (components) is a common way , It includes the engine room sealing strip, front and rear windshield sealing strips, door frame sealing strips, door sealing strips, door glass guide groove sealing strips, door lower dust strips, door and window sill internal and external sealing strips, side window sealing strips, sunroof sealing strips , Roof cover sealing strip, trunk (luggage) sealing strip, etc., installation method: self-contained double-sided tape, can be directly pasted (the pasting surface must be smooth, clean, smooth, and dry). It is widely used in box sealing and In the field of building sealing, the cold resistance, heat resistance, foaming, solid, and special properties of the different application fields developed and designed by our company can meet the application needs. The installation method of the inlaid wooden door sealing strip: because each manufacturer is opening The width of the saw blade or grooving knife used for grooving is different. Usually there are 4mm, 3mm, 2.5mm, 2.0mm. Most of them use 3mm. You must be optimistic when you use the sealing strip. According to the cross-sectional shape, the flame-retardant and high-temperature resistant silica gel special-shaped strips can be classified into solid products (round, square, flat cross-sectional shapes), hollow products and metal rubber composite products. Among them, metal rubber composite sealing strips account for more than 60% , For the rubber sealing strip, 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 Classification, can be divided into weather sealing strip (WEATHERSTRIP) and general sealing strip (SEALING). Sealing strips are made of rubber, paper, metal, plastic and other materials. Low-end products use waste materials, substitute plasticizers and High filling volume, to make the rubber strips have poor elasticity, easy to become hard, have a nasty smell, easy to migrate, make the frame material yellow, and have a short service life. Features 1. EPDM has excellent weather resistance and weather resistance means long-term The ability to resist severe cold, heat, dryness, and humidity, and has excellent corrosion resistance to rain and snow erosion, which can completely extend the service life of the rubber strip
