How is the sealing of doors and windows? The rubber strip plays a crucial role

In building materials, sealing strips are often overlooked due to their low cost and traditional lack of emphasis on energy-saving standards for doors and windows. However, sealing strips play a crucial role in building sealing and energy efficiency, and are also a key component of building energy efficiency. Especially EPDM sealing strips, due to their excellent performance, are widely used in the fields of building curtain walls and doors and windows, playing a key role in building energy conservation.

The characteristics of EPDM strips: EPDM is a copolymer of ethylene, propylene, and a small amount of a third monomer, known as crack free rubber, and is widely recognized as the * * material for producing sealing strip products in the world. EPDM rubber strips have excellent resistance to sunlight and ultraviolet rays, weather resistance, heat aging, high and low temperature resistance, ozone resistance, chemical resistance, water resistance, good electrical resistance and elasticity, as well as other physical and mechanical properties. Therefore, they have surpassed most rubber strip materials on the market and can be widely used in automotive components, waterproof materials for construction, wire and cable sheaths, heat-resistant rubber hoses, tapes, automotive seals and other fields.

Our company's main product is EPDM sealing strips, and the registered trademark is "Rising" brand. The main function of EPDM door and window sealing strips is to seal and fix doors, windows, and curtain wall glass. The main raw material is EPDM original rubber. The company has always used imported EPDM original rubber produced by DuPont in the United States, and the carbon black used is a product from Germany's Guisai Chemical Co., Ltd. Other auxiliary materials are also selected from domestic legitimate companies. We do not seek low prices but only good quality.

The advantages of EPDM rubber strips are stable product performance and good usability. Anti aging and corrosion resistance. The physical indicators such as UV resistance, stretchability, and aging resistance of the product remain basically unchanged under the conditions of -40 ° C to 160 ° C.

How durable are the EPDM rubber strips produced by our Rising company? In many cases, other rubber strips simply cannot hold on!

1. Aging resistance: Due to the lack of polarity and low unsaturation of ethylene propylene rubber, it has good resistance to various polar chemicals such as alcohols, acids, bases, oxidants, refrigerants, detergents, animal and vegetable oils, ketones, and fats.

2. Water vapor resistance: EPDM rubber strips have excellent water vapor resistance and are superior to their heat resistance. After being immersed in superheated steam at 230 ℃ for nearly 100 hours, there was no change in appearance.

3. Heat resistance: EPDM rubber strips also have good heat resistance, but it is closely related to the vulcanization system used. The mechanical properties of the ethylene propylene rubber strip vulcanized with dithiomorpholine and TMTD as the vulcanization system changed very little after soaking in 125 ℃ superheated water for 15 months, with a volume expansion rate of only 0.3%.

4. Elasticity: There are no polar substituents in the molecular structure of EPDM rubber strips, resulting in low cohesive energy. The molecular chains can maintain flexibility over a wide range, second only to natural rubber and butadiene rubber, and can still be maintained at low temperatures. Long term use can also maintain good firmness and sealing, while effectively achieving sound insulation and dust prevention performance.

5. UV and radiation resistance: EPDM rubber strips can provide environmental protection for residents of high-rise buildings. Withstand voltage of 60-150KV, resistant to corona, electric cracking, and arc. Low temperature elasticity, when the tensile capacity reaches 100MPA, the temperature is -58.8 degrees Celsius.

Although the EPDM rubber strips produced by Rising Company are very durable, quality, craftsmanship, and our company's service capabilities are the key to ensuring their performance. Although the rubber strip is small, its function cannot be ignored. It not only needs to be beautiful, but also durable. Especially for building curtain walls and door and window products, which are related to people's lives and property safety, our company recommends that when choosing rubber strips, enterprises must choose to cooperate with reliable quality, strong manufacturing and service capabilities, and not be greedy for small things and lose big things!
