A snow equipment wax composition including at least 65 wt % of candelilla wax and sunflower wax; at least 20 wt % of pillar blend soy wax; and up to 15 wt % of one or more additional materials selected from the group of additional waxes, natural plant oils, and hydrogenated plant oils.

Recycled elements and/or renewable resources, such as recycled carbon black or recycled carbon black and recycled particulate rubber, are incorporated into a rubber composition. The rubber composition can be used to manufacture tires or various tire components including tire subtreads.

A tackifier to modify the Tan Delta of midblock segments of a hydrogenated styrenic block copolymer in a thermoplastic elastomer compounds aids in rendering the HSBC TPE more effective as an overmolding compound having a low percentage compression set value when measured at the high temperature compression set standard. The HSBC TPE can overmold effectively upon polar polymeric substrates depending on the bonding agent chosen.

Each D is independently S or N(H) and R is a monovalent alkyl, alkenyl, or polyalkyleneoxy or a multivalent alkylene, alkenylene, or polyalkyleneoxy, wherein the alkyl, alkenyl, alkylene, or alkenylene are each interrupted by at least two O, N(H), N(H)C(O), SC(O), or OC(O) groups or a combination thereof. A method of repairing a damaged surface using the composition is also described.

The present invention is directed to a pneumatic tire comprising a vulcanizable rubber composition, the vulcanization rubber composition comprising: 1) 100 parts by weight of elastomer consisting of 25 to 35 phr of a styrene-butadiene rubber, 25 to 35 phr of a polybutadiene, and 35 to 45 phr of a natural rubber or synthetic polyisoprene, wherein the styrene-butadiene rubber is a functionalized solution polymerized styrene-butadiene elastomer having a glass transition temperature Tg(A) ranging from 30 to 10 C. and having at least one functional group; the natural rubber or synthetic polyisoprene has a Tg(B) ranging from 60 to 70 C.; and the polybutadiene is a cis 1,4 polybutadiene having a Tg(C) ranging from 110 to 90 C., wherein Tg(A)Tg(B)25 C., and Tg(B)Tg(C)25 C.; 2) 60 to 80 phr of a prehydrophobated silica; 3) 1 to 10 phr of carbon black; 4) 1 to 3 phr of rubber processing oil; and 5) 5 to 25 phr of at least one hydrocarbon resin having a Tg20 C., wherein the weight ratio of hydrocarbon resin to rubber processing oil is greater than 8.

The invention relates to a tire having a tread of carbon black reinforced rubber composition containing a specialized styrene/butadiene elastomer with molecular weight profile containing a limited low molecular weight content and triglyceride vegetable oil.

Present invention is related to a bio-degradable composition having: PVC powder 100 phr, a plasticizer 4060 phr and an enzyme 0.54 phr. The bio-degradable material has degradation rate over 90% under anaerobic environment. The combination of plasticizer and enzyme give the present invention the ability of degrading. Because there is no additional bio material involved, the physical property and mechanical property of the present invention can be remained. Since the products made by the present invention only can be degraded under anaerobic environment, the products can maintain in good condition or qualities under normal circumstances with the existing of oxygen.

The present invention is directed a tire comprising two rubber components which are co-cured together.
