PRODUCTION OF FOAMED SEAL MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a foamed seal member capable of being produced in simple process without requiring a coating process and a drying process, capable of being recycled after used, and having excellent lubricity and abrasion resistance on the surface of the foamed seal member suitable for especially an automotive weather strip or an automotive trunk seal. SOLUTION: This method for producing a foamed seal member by foaming a thermoplastic elastomer includes a process for heating process for thermally melting a thermoplastic elastomer, a mixing process for adding and mixing the aqueous dispersion of a silicon compound to the melted thermoplastic elastomer under pressurization to produce the foamed mixture, and a foaming process for releasing and foaming the foamed mixture in the atmospheric pressure.
