  • Low moisture permeability laminate construction
    Patent number: 10427457
    Abstract: A tire comprising an outer tread layer, intermediate sidewall and carcass layers and an innermost air permeation prevention layer: (i) the air permeation prevention (APP) layer having an upper and a lower surface, the layer having a polymer composition exhibiting an air permeation coefficient (APC) of about 25×10?12 cc cm/cm2 sec cmHg (at 30° C.) or less and a Young's modulus of about 1 MPa to about 500 MPa, the polymer composition comprising: (A) at least 10 wt % of at least one thermoplastic resin component having an APC of about 25×10?12 cc cm/cm2 sec cmHg (at 30° C.) or less and a Young's modulus of more than 500 MPa, which is preferably a polyamide resin or mixture, and (B) at least 10 wt % of at least one elastomer component having an APC of more than about 25×10?12 cc cm/cm2 sec cmHg (at 30° C.

  • Low moisture permeability laminate construction
    Patent number: 8960250
    Abstract: An article having a fluid permeation prevention layer, such as a pneumatic tire or hose. A tire for example includes an outer tread layer, intermediate sidewall and carcass layers and an innermost air permeation prevention layer: (i) the air permeation prevention (APP) layer having an upper and a lower surface, the layer having a polymer composition exhibiting an air permeation coefficient (APC) of about 25×10?12 cc cm/cm2 sec cmHg (at 30° C.) or less and a Young's modulus of about 1 MPa to about 500 MPa, the polymer composition comprising: (A) at least 10 wt % of at least one. thermoplastic resin component having an APC of about 25×10?12 cc cm/cm2 sec cmHg (at 30° C.) or less and a Young's modulus of more than 500 MPa, which is preferably a polyamide resin or mixture, and (B) at least 10 wt % of at least one elastomer component having an APC of more than about 25×10?12 cc cm/cm2 sec cmHg (at 30° C.
