Different parts of automobile sealing strips have different requirements for sealing performance and weather resistance. Good sealing strips can ensure the normal operation of various parts of the car, improve the overall sealing of the car, and enhance the driving experience.

Usually, EPDM rubber can be used for door sealing strips, because the car doors are exposed to the external environment for a long time, and EPDM rubber is resistant to aging, has good weather resistance, and has a long service life; neoprene can be used for engine compartment sealing strips, because the temperature in the engine compartment is high, and neoprene can be flame retardant and high temperature resistant, protecting the engine compartment parts from high temperature. At present, due to the good flexibility of thermoplastic elastomers, some car side window sealing strips can use thermoplastic elastomers.
