classification:
1, vulcanized rubber sealant strip, this range of application is generally from minus sixty degrees to minus one hundred and fifty degrees, but the disadvantage is that it will expand and deform in mineral oil and lubricating oil.
2, silicone rubber sealant strip, this range of application is zero Baidu to zero on three Baidu, can be used for food packaging, but the disadvantage is that it is not resistant to oil, mechanical strength is relatively poor.
3, neoprene sealant strip (CR), this range of application is from minus 30 degrees to minus 120 degrees, the disadvantage is that cold resistance is not good.
4, nitrile rubber sealing strip, this feature is oil resistant, elastic is better, but easy to oxidize, cold resistance is relatively poor.
5, thermoplastic elastomer type sealing strip, good wear resistance, good oil resistance, can be applied to minus 60 degrees to 80 degrees above zero.
6, thermoplastic vulcanizate (TPV) sealing strip, suitable for minus 40 degrees to zero to 150 degrees, waste can be recycled, very good in environmental protection.
7. Plasticized polyvinyl chloride (PPVC) sealing strip, which is cheap in material, not resistant to aging, and has poor weather resistance and low temperature performance.
How to maintain the car seal:

4. The current car has a car sunroof. When the sunroof is open, it is exposed outside. Therefore, the rubber strip on the sunroof is very easy to oxidize, or it is subject to acid rain and erosion. This will easily cause the skylight to leak, so clean it regularly. Tracks, it is important to apply lubricant to the track.
5. After the window glass is damaged, the owner should check the seal for damage when changing the glass.
