Patent ID: 8353130

Claim:
A door weather strip, comprising: an attaching base part that is fitted to an attachment position of a peripheral edge of a door for a vehicle; and a seal part that is extended along an outer periphery of the door from the attaching base part and is allowed to come into contact with a peripheral edge of an opening of the door of a vehicle main body under pressure when the door is closed, wherein both the attaching base part and the seal part comprise the same composition of an EPDM (ethylene-propylene-diene copolymer) sponge rubber material, wherein the door weather strip includes a specific gravity in a range from 0.36 to 0.44, inclusive, a stretch stress in a range from 200 kPa to 230 kPa, inclusive, and an average foaming cell diameter in a range from 180 μm to 220 μm, inclusive, wherein the EPDM sponge rubber material comprises a first EPDM polymer and a second EPDM polymer having a molecular weight less than a molecular weight of the first EPDM polymer, and wherein the first EPDM polymer includes a Mooney viscosity ML1+4 (125° C.) of 100 to 180 and the second EPDM polymer includes the Mooney viscosity ML1+4 (125° C.) of 20 to 60.
