摘要： PROBLEM TO BE SOLVED: To provide a weather strip which is excellent in external appearance and sealing performance by solving the problem of the hollow seal part in a prior weather strip in which hollow seal part was low in the surface smoothness and surface brightness and easily wrinkled on folding. SOLUTION: The hollow seal part 13 is equipped with a hollow seal part which is extruded into a desired shape in a thermal plastic elastomer composition by mixing a component (f) (foaming agent) with a thermal plastic elastomer composition and foaming the thermal plastic elastomer composition so that the hollow seal part remarkably improves in the surface smoothness, surface brightness and R following performance by the foaming action of the foaming agent to permit imparting the desirable external appearance and elastic deformation.

摘要： PURPOSE:To manufacture a bulky foam at low cost, by performing foam molding of thermoplastic resin through a specific extrusion foaming method. CONSTITUTION:A large number of extrusion holes 51 is arranged on a cap 5 provided on the tip of an extruding machine and when a distance of said extrusion holes, an extrusion hole diameter and expansion magnification to be obtained when free foam has been performed through the extrusion hole are made respectively into L, D and R, relation among them is made into an expression I. In addition to the above, after a foamed fine stripe extruded through the foregoing cap has been introduced into a shaping device 6 surrounded by rolls 61, 62, relation to be obtained when a take-off rate taking off the stripe and an extrusion rate through an extrusion hole are made respectively into v and V is made into an expressionII. Bulky thermoplastic foam whose apparent expansion coefficient is large is manufactured by mutually fusing foamed stripes extruded under these terms.
