Disclosed herein are polymeric blends suitable for use in non-pneumatic tires, processes for preparing the polymeric blends, and non-pneumatic tires and components thereof incorporating the polymeric blend. The polymeric blends include a thermoplastic polyester elastomer and a crosslinking compound.

Temperature stable polymeric blends for use in non-pneumatic tires

Disclosed herein are polymeric blends suitable for use in non-pneumatic tires, processes for preparing the polymeric blends, and non-pneumatic tires and components thereof incorporating the polymeric blend. The polymeric blends include a thermoplastic polyester elastomer, a high temperature thermoplastic polymer, a compatibilizer resin, a delayed crosslinking agent, and an activator.

A vulcanizable composition comprising rubber component, a filler, and a curing agent, where the rubber component includes a block copolymer of polybutadiene and polyisoprene, and where the block copolymer has a cis content of at least 90%.

High cis-1,4 block copolymers of polybutadiene and polyisoprene

The present disclosure relates to a rubber composition that includes an aromatic-compound based resin and a styrene-butadiene copolymer and a tire using the same as the tread rubber or a component thereof. The rubber composition provides improved wet traction.

Tread composition and tire produced by using the same

Embodiments of 1,4-polybutadiene rubber compositions useful at low temperatures are provided, wherein the 1,4-polybutadiene incorporated therein comprises a cis content of at least 85 to about 92%, a vinyl content of at about 1% to about 5%, and a trans content of about 3 to about 12%, and wherein the 1,4-polybutadiene has an enthalpy of melting &#x394;Hof about 5 to about 25 J/g&#xb0; C. as measured via differential scanning calorimetry (DSC).

Polybutadiene polymers and rubber compositions incorporating same for low temperature applications

A tire mold has a cavity with a flexible bladder disposed in a central portion of the cavity. The tire mold further includes a first ring connected to a first end of the flexible bladder, and a second ring connected to a second end of the flexible bladder. At least one of the first and second rings is configured to move between a first position and a second position. The flexible bladder is stretched to a maximum axial length when the first and second rings are in a first position. When the first and second rings are in the first position the sum of the first axial length and second axial length is greater than a space between the first ring and the second ring.
