Automotive weatherstrips are mainly foamed from EPDM rubber with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical action, and a wide operating temperature range (-40 ° C to + 120 ° C). It is made of dense compound and contains unique metal clamps and tongue buckles, which is durable and easy to install.

In the low temperature resistance test at -40 ° C, the sealing rubber strip does not harden, is not brittle, still maintains softness and good adhesion of the rubber strip, showing excellent cold resistance. At a high temperature of 120 ° C, the weather resistance of the weather strip is still good, maintaining its elastic properties, and its shape and function have not been affected.
