The difference between silicone strip and silicone foam strip

by:Kenna     2021-06-14
The difference between silicone strips and silicone foam strips, car sealing strips can be classified into solid core products (round, square, flat cross-sectional shapes), hollow products and metal rubber composite products according to the cross-sectional shape. Second, heat resistance The aging EPDM sealing strip has been tested many times before production. It can be seen from the experiment that the product can continue to work in a high-temperature environment without aging. Therefore, many companies have adopted the product The use of to improve work efficiency, so as to obtain more profits. 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 'specialization' difference between silicone strips and silicone foam strips originated from Germany and has been popular in the European market for a long time. It is famous for its environmentally friendly sealing performance. The sound insulation, heat preservation, sealing and impact resistance of the coated sealing strips The characteristics of sex and environmental protection have attracted more and more consumers’ attention. 'Functionality' has long been a functional, rational and reliable image of German design, especially in terms of technology, function, logic and sense of order. The level of harmony and unity,' the covered sealing strip structure makes the door leaf and the door cover tight and seamless, and has stronger sound penetration resistance, and has strong resilience, sound insulation and environmental protection. The high-quality Either the internal quality or the later use will improve the overall style and performance of the door, and the covered sealing strip is the modern development trend. Where can the covered sealing strip 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, copper doors, cast aluminum doors, plastic steel doors and windows Etc. The skeleton sealing strip is co-extruded by dense rubber, foam rubber and steel wire/steel sheet. Also known as EPDM sealing strip (EPDM)-suitable for special environments from -40℃ to +160℃, with Superior ozone resistance, UV resistance, chemical solvent resistance, various physical and chemical performance indicators far exceed similar products. The difference between silicone strips and silicone foam strips is heat resistance, cold resistance, insulation and conductivity. Flame retardancy is very good. 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. In case of sudden accidents in urban buildings, it can play a delaying role; coupled with the use of special formulas, EPDM rubber feels similar at -50°C to 150°C, which creates high-efficiency work performance for installation on the production site. In fact, there are many places in our lives that cannot be separated from this product, because its use effect is very good, friends who don’t know can join me to take a look at the characteristics of EPDM sealing strip. Third, ozone resistance The ozone resistance of the product is very good, and it can be completely exposed to the air to work, so that the superiority of the product is more prominent, and the anti-ultraviolet radiation effect of the EPDM sealing strip is also very good. It also has excellent physical and mechanical properties, so it is often used to make airplanes, trains, cars, etc. Car sealing strips can be classified into solid core products (round, square, flat cross-section shapes) according to the cross-sectional shape , Hollow products and metal rubber composite products, and second, heat aging resistance EPDM sealing strips have been tested many times before production. From the experiments, it can be seen that the products can continue to work in a high temperature environment. And there will be no aging phenomenon, so many companies use products to improve work efficiency, so as to obtain more profits. It is widely used in the fields of box sealing and building sealing. The development and design of our company are different. Cold and heat resistant in the field of use , Foaming, solid, and special properties can meet the application needs. The installation method of the inlaid wooden door sealing strip: because the width of the saw blade or the grooving knife used by each manufacturer when grooving is different, There are usually 4mm, 3mm, 2.5mm, 2.0mm, and 3mm is mostly used. You must be optimistic when you use it when purchasing sealing strips. The difference between silicone strips and silicone foam strips is that PVC products contain halogens and heavy metals in stabilizers, which 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, which are flexible at low temperatures and stretch. The temperature when the capacity reaches 100MPa is -58. EPDM 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. Where can it 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., 035W/m2K; 5. Fatigue resistance test: imitating window opening and closing 500,000 times, no obvious change in shape 6. Sound insulation test: only IV68 windows with intermediate rubber strips, reducing noise 43 Decibel 7, IV76 windows with intermediate strips and additional strips, reduce noise by 45 decibels
