Bring up the sealing strip, we are all very familiar with, in daily life and work often come into contact with, from the window sealing strip, furniture sealing strip, to the refrigerator freezer sealing strip and so on, very common, the role is also very obvious. There are many classifications of sealing rubber strip, generally different materials of sealing rubber strip suitable for different places. Next xiaobian will introduce the material of sealing tape used in different places.
1. Silicone rubber sealing tape, this tape has very good high temperature and low temperature resistance, and has excellent hydrophobicity and permeability. The sealing tape of this material is insulated, and the temperature range of use is -100 ℃ ~ + 300 ℃. But this kind of sealing tape has poor mechanical strength and is not resistant to oil.
2, nitrile rubber sealing strip, the characteristics of this sealing strip is + points oil resistance and solvent resistance, its elastic performance is very good, but this sealing strip in Ozone and oxidation environment is prone to aging and cracking, and its cold resistance is poor.
3, thermoplastic elastomer sealing rubber strip, this sealing rubber strip has good elasticity and wear resistance, mechanical properties are very superior, not only that, thermoplastic elastomer sealing rubber strip also has excellent cold resistance and chemical corrosion resistance. But this kind of sealing tape is made of high material, which is a kind of recyclable material, suitable for some industrial sites and railway and other places. 4. Plasticized polyvinyl chloride (PPVC) sealing strip, this sealing strip has good corrosion resistance and wear resistance, high mechanical strength. And plasticized polyvinyl chloride (PPVC) sealing tape material is very cheap and easy to obtain, but this sealing tape will become lost elasticity and aging with the passage of time, its weather resistance and low temperature resistance is poor. Suitable for places where light intensity is not strong and temperature is not too low.
