Abstract
A self-sealing valve for a tyre includes at least a part formed of a self-sealing material having a dynamic shear modulus G*, measured at 10 Hz, less than or equal to 0.06 MPa, preferably less than or equal to 0.03 MPa, and more preferably still, less than or equal to 0.01 MPa.
Claims18
A self-sealing valve formed of, at least in part, a self-sealing material that includes at least one elastomer that has a dynamic shear modulus G*, measured at 10 Hz, less than or equal to 0.06 MPa, wherein the valve may be used for a tyre, for a wheel rim, or for an inner tube.
A composition comprising:
- a thermoplastic styrene elastomer;
- and
- an extension oil in a proportion ranging between 200 and 700 parts by weight per hundred parts elastomer,
- wherein the composition is used for manufacturing a valve for a tyre, a wheel rim, or an inner tube.
