Abstract
A weather strip or glass run for an automotive vehicle. The weather strip comprises a main body formed of an elastomer. A slidably contacting section to which a part other than the weather strip is slidably contactable is fixedly formed on the main body and contains a material having at least one of hydrophilicity and water absorbability. The slidably contacting section may be integral with the main body to form a one-piece structure, in which the slidably contacting section is formed of the elastomer, and the elastomer of the main body and the slidably contacting section contain the material having at least one of hydrophilicity and water absorbability.
Claims23
A weather strip comprising:
- a main body formed of an elastomer;
- and
- a slidably contacting section to which a part other than the weather strip is slidably contactable, said slidably contacting section being fixedly formed on said main body and containing a material having at least one of hydrophilicity and water absorbability, wherein said slidably contacting section having a contact angle of water of less than 850 as measured at a temperature of 23°C. and a relative humidity of 50%.
A weather strip comprising:
- a main body formed of an elastomer;
- and
- a slidably contacting section to which a part other than the weather strip is slidably contactable, wherein said slidably contacting section being fixedly formed on said main body and comprising a powder and/or fibrous material, having an elastic modulus ranging from 350 to 1300 MPa as measured at a temperature of 23° C. and a relative humidity of 50% and wherein said slidably contacting section having a contact angle of water of less than 85° as measured at a temperature of 23° C. and a relative humidity of 50%.
A weather strip comprising:
- a main body formed of an elastomer;
- and
- a slidably contacting section to which a part other than the weather strip is slidably contactable, wherein said slidably contacting section being fixedly formed on said main body and formed of a material having an elastic modulus ranging from 90 to 250 MPa as measured at a temperature of 23° C. and a relative humidity of 50% and wherein said slidably contacting section having a contact angle of water of less than 850 as measured at 23° C. and a relative humidity of 50%.
A weather strip comprising:
- a main body formed of an elastomer;
- and
- a slidable contacting section to which a part other than the weather strip is slidably contactable, said slidable contacting section being fixedly formed on said main body and containing at least one material of powder material and fibrous material, having an elastic modulus ranging from 350 to 1300 MPa as measured at a temperature of 23° C. and a relative humidity of 50%.
A weather strip comprising:
- a main body formed of an elastomer;
- and
- a slidable contacting section to which a part other than the weather strip is slidably contactable, said slidable contacting section being fixedly formed on said main body and formed of a material having anelastic modulus ranging from 90 to 250 MPa as measured at a temperature of 23° C. and a relative humidity of 50%, and wherein said slidable contacting section has a surface tension within a range of not lower than 3.8×10−2 N/m as measured at a temperature of 23° C. and a relative humidity of 50%.
