Characteristics of automobile U-shaped composite sealing strip with foam
In the -40°C low temperature resistance test, the sealing tape did not become hard and brittle, and still maintained softness and good adhesion of the tape, showing excellent cold resistance. At a high temperature of 120°C, the weather resistance of the sealing strip is still good, maintaining elastic properties, and the shape and function are not affected.　　　　　
The choice of seal material determines its permanent softness and elasticity. Through formula adjustment, the softness of the sealant after drying is improved, so that it forms a good sealing layer between the sheet metal and the rubber strip, which is unique to butyl rubber High elasticity, to ensure that the sealant is easy to peel from the metal sheet metal without polluting the sheet metal.
Automobile sealing strips are mainly made of EPDM rubber foam with good elasticity and resistance to compression deformation, aging resistance, ozone, chemical effects, and a wide temperature range (-40℃~+120℃) It is made of dense composite, and contains unique metal clamps and tongue buckles, which is durable and easy to install.
