Hard silicone strip

by:Kenna     2021-04-27
Hard silicone strips, of which 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 be the same and appropriate in size. The force touches the glass from both sides of the car window glass. 3) It has an independent open-cell bubble structure. 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 hairening. , Adapt to changes in natural expansion and contraction, and enhance the effect of seam sealing, expansion and water stop. Introduction to the electrical cabinet door self-adhesive sealing strip is composed of three types with good elasticity and resistance to compression deformation, resistance to aging, ozone, chemical effects, and a wide operating temperature range (-40℃~+120℃). Ethylene propylene rubber (EPDM) rubber is foamed and densely compounded. It contains unique metal clamps and tongue-shaped buckles, which is sturdy and durable. It plays a key role in various electrical cabinets. The rigid silicone strip is mainly used in the door frame, side window, front and rear windshield, engine cover and trunk cover, and plays the role of waterproof, dustproof, sound insulation, temperature insulation, shock absorption, and decoration. Unique formula The design makes EPDM rubber seals have excellent anti-aging, high and low temperature resistance and chemical resistance performance, good elasticity and compression deformation resistance, long-term use will not be cracked or deformed, at -50 degrees to It can maintain its original high sealing performance between 120 degrees. , Elastomer TPE water floating sealing strip is applied to door and window sealing strip, mainly divided into: plastic steel door and window sealing strip, aluminum alloy door and window sealing strip, wooden door sealing strip, cold storage door sealing strip, grain storage door sealing strip, flame retardant door and window sealing strip , Glass sealing strips, automatic revolving door sealing strips, building door sealing strips, curtain wall sealing strips, etc., the so-called sealing strips with pores inside, this product is formed at one time through the microwave vulcanization process during production. Therefore, the surface is not only very smooth, but also has good aesthetics. It will not leave any joint marks during production. At the same time, the elasticity and resistance to compression deformation are also very strong. Let us take a detailed look at the hair The characteristics of the bubble 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. In the raw materials for the manufacture of sealing strips, the main raw material EPDM used in the past is also constantly updated and developed. The new type of EPDM with excellent physical properties and good processing properties can control the long-chain branching in the molecule. , Make its vulcanization performance better, and can increase the extrusion speed and product output. These materials not only have the excellent engineering performance of elastomers, but also have the excellent characteristics of plastics. They are convenient for processing and can be recycled and reused. These materials are now Gradually replace EPDM products. With the improvement of people's living standards, the improvement of housing conditions and people's high attention to home decoration, more and more people pay attention to the privacy, sound insulation and sealing effect of indoor rooms, 035W/m2K; 5. Fatigue resistance test: imitation The window has been opened and closed 500,000 times without significant changes in shape. 6. Sound insulation test: only IV68 windows with intermediate rubber strips, reducing noise by 43 decibels7, IV76 windows with intermediate rubber strips and additional rubber strips, reducing noise by 45 decibels8, Outdoor aging resistance test: It has been more than 20 years, and the performance is maintained intact. The series of products are environmentally friendly products and do not contain CFC harmful substances. Fourth, the impact resistance is good. Many people want to use foam sealing strips as cushioning materials, because the impact resistance of this product is very good, the physiological stability of the rubber sealing strips is very good, and the resistance to deformation is also very good. It is strong, not only resistant to ozone but also resistant to ultraviolet rays, so this product has been widely used, and it is inseparable from many places such as medical diversion, electronics, wire and cable, etc. , This product also has a very good advantage, that is, long service life. 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, usually there are 4mm, 3mm, 2.5mm, 2.0mm, and most of them are 3mm. They are used in the purchase of seals. Be optimistic about the article. Hard silica gel strips are still used 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 are often used in manufacturing. Airplanes, cars, trains, passenger cars, ships, high and low voltage switch cabinets, glass curtain walls, aluminum alloy heat-breaking window sealing parts and diving products, high-pressure steam hoses, tunnels, viaduct joints and other waterproof parts and other industrial and 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 properties 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 known as fluidized bed vulcanization). , The heating medium is medium 0.
