What Kind Of Sealing Strip Is Generally Used For Doors And Windows?

Doors and windows not only play the role of safety protection in the home environment, but also have functions such as sound insulation, dust-proof, antifreeze, and heat preservation. The selection of doors and windows is very important, and the selection of accessories for doors and windows should not be sloppy. Today, I will take you to take a look at the sealing strips used in daily doors and windows.

There are many types of door and window seals, generally made of PVC, elastic seals, silicone and other materials. The rubber sealing strip has good waterproof, sealing and energy-saving effects, and effectively provides great help and convenience to humans. So what kind of sealing strip is generally used for doors and windows?

1. PVC sealing strip

It has the advantages of corrosion resistance, wear resistance, combustion resistance, and high mechanical strength. The disadvantage is that it becomes hard and fragile with time, loses elasticity, is not resistant to aging, has poor weather resistance, and poor low temperature performance.

2. Thermoplastic vulcanization sealing strip

With the flexibility and elasticity of Chinese rubber, it can be produced by processing plastic products without vulcanization, and the waste can be recycled and reused. It is a material with a wide range of properties, good heat resistance, low relative density, oil resistance similar to neoprene, compression set and wear resistance are not very good. Use within the temperature range of minus 40 degrees Celsius to 150 degrees Celsius. Suitable for cold buildings, but also for corporate high-level management buildings.

3. Polyurethane rubber

It has good flexibility and excellent wear resistance, good hardness, good mechanical properties, excellent resistance to cold weaving and chemical resistance. It can meet the requirements of various colors of enterprises. The operating temperature range is minus 60 degrees Celsius to 80 degrees Celsius. Suitable for areas prone to earthquakes, where railways, power plants and other cranes are close to areas of strong vibration, but also for areas with strong UV radiation.

4. EPDM rubber strip

The main material selection is based on Lanxess,DSM,Korea Kumho EPDM and other manufacturers of raw rubber,Cabot carbon black,advanced microwave curing production line.

EPDM has excellent resistance to ozone,weathering resistance,heat aging resistance,excellent electrical insulation properties,good chemical stability.And the basic properties is 70±5A,temperature is 120-150℃,low temperature is -50℃ not broken.Also the material properties of the implementation of GB/T 24498-2009 building windows and doors,curtain wall sealing strip.

The four kinds of door and window sealant strips introduced above have their own advantages, and you can choose according to the actual situation in your area. What suits you is the best!
