Which is better, silicone strip and lycra?

by:Kenna     2021-06-14
Which is better, silicone strip or Lycra, wooden door, door and window sealing strip product features: self-adhesive wooden door sealing strip is made of EPDM rubber foam, creating its excellent characteristics, door and window sealing strip features plastic-steel door and window sealing This new generation of doors and windows has been widely used in recent years. Compared with ordinary door and window sealing strips, it has better anti-corrosion, weather resistance, noise reduction and heat insulation effects. The rubber materials of the sealing strips are more resistant to aging, low temperature, and moisture resistance. Chemical resistance, especially ethylene propylene diene monomer (EPDM), which is resistant to ozone aging. Automobile product rubber formula and its preparation method and process Background technology: At present, the low temperature performance of rubber products used in automobiles on the market is generally around -25°C, but the rubber parts on automobiles cannot withstand cold air in a harsh climate. The airflow caused the product life to be greatly reduced. The performance of rubber products used in automobiles directly affects personal safety. For example, the recall of some of the cars sold by Toyota in the past few years caused serious reputational consequences. Therefore, all automobile manufacturers need a long-term stable performance. Adequately safe rubber products. Silicone strips and Lycra sealing strips are made of rubber, paper, metal, plastic and other materials. Low-end products use waste materials, substitute plasticizers, and high filling levels, which make the rubber strips less elastic. Easily hard, nasty smell, easy to migrate, yellowing the frame material, short service life, characteristics 1, EPDM has excellent weather resistance, weather resistance refers to long-term resistance to severe cold, heat, dryness, and humidity. It has excellent corrosion resistance to the erosion of rain and snow, which can completely extend the service life of the rubber strip; 2. Heat aging resistance refers to strong heat resistance air aging. At a high temperature of 120°C, the weather resistance of the sealing strip is still good, and the elasticity is maintained. The shape and function are not affected. The low temperature elasticity, the temperature when the tensile capacity reaches 100MPa is -58, and the characteristics of the neoprene sealing strip: 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, good chemical resistance and excellent flame resistance. , Has good stickiness. According to the name of the installation part (component), the classification includes: engine cover sealing strip (HOOD), which can be divided into front, side and rear; door frame sealing strip (DOORSEAL); front and rear wind window sealing strip (WINDOWSCREEN); Side window sealing strip (SIDEWINDOWSEALING); sunroof sealing strip (SUNROOFSEALING); door first road sealing strip (PRIMARYDOORSEAL); window guide groove sealing strip (GLASSRUNCHANNEL); inside and outside strips (water cut) (WAISTLINE); trunk sealing strip (TRUNKSEAL) ; Anti-noise sealing strip (ANTI-NOISE); Dust-proof strip (ANTI-DUST), etc. Technical realization factors: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low-temperature performance, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety. Technical realization factors: The technical problem to be solved by the present invention is to provide a rubber formula for automobile products and a preparation method thereof, which has good low-temperature performance, can withstand the attack of cold air in a local environment with relatively bad weather, and guarantees good performance. Ensure personal safety. Silicone strips and lycras, which are more expensive, are fifteen or six thousand yuan per ton, and the cheap one is only 6,000 yuan per ton. The price difference is nearly 10,000 yuan, and the quality difference is very big, which is confusing. Many sealing strip manufacturers say Its products are in accordance with the GB12002-89 standard, and can issue test reports qualified by authoritative institutions. The sealing strips are classified 1, 2 according to the surface treatment state. Part of the sealing strip surface can be divided into flocking sealing strips after additional treatment; Surface coating sealing strip; with fabric patching sealing strip. High-quality products will improve the overall style and performance of the door in terms of appearance, internal quality, or later use. Wrapped seals are a modern development trend. Where can wrap seals 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. Among them, 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 removed from the car with the same and appropriate force. The two sides of the window glass touch the 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. It can be tightly bonded with cement/sealant without being roughened, and it can adapt to natural expansion The shrinkage changes and changes to enhance the sealing, expansion, and water stop effect of the joint.
In an age when rubber seal strip suppliers is increasingly important, the researchers believe manufacturers should pay close attention to their results.
As manufacturers we are determined to be the very best in rubber seal strip suppliers, regardless of the size, pedigree or inclinations of our competitors.
rubber seal strip suppliers has its grasp on oversees market and has a very good repute. Our products are available at very competitive prices.
