摘要： Expandable bladders for use in curing presses for hydrocarbon rubbers, such as pneumatic tires, are a crosslinked elastomer composition comprising isobutylene repeat units and including a fluorinated ethylene polymer added in particulate form and thereafter dispersed throughout the bladder. These fluorinated ethylene polymer may or may not form fibers. The bladders may further comprise graphite. A preferred isobutylene elastomer is a brominated copolymer of from 80 to 99 weight percent isobutylene and from 1 to 20 weight percent paramethylstyrene. The bladders have enhanced lubricity, reduced adhesion to cured tire innerliners, better resistance to cracking during flexing, and have lower tension set than similar compositions without fluorinated ethylene polymers. The above enhancements allow hydrocarbon rubbers such as tires to be molded with fewer defects caused by abraded or deformed bladders. They also enhance the useful life of the bladder reducing the cost of tire curing.

摘要： Expandable bladders for use in curing presses for hydrocarbon rubbers, such as pneumatic tires, are a crosslinked elastomer composition including isobutylene repeat units. When PTFE and/or graphite is present, they can be cured with brominated phenolic resins in shorter periods of time. The fluorinated ethylene polymer is added in particulate form and thereafter dispersed throughout the bladder. The fluorinated ethylene polymer may or may not form fibers. The bladders may further include graphite. The bladders generally have enhanced lubricity, reduced adhesion to cured tire innerliners, better resistance to cracking during flexing, and have lower tension set than similar compositions without fluorinated ethylene polymers. The above enhancements allow hydrocarbon rubbers such as tires to be molded with fewer defects caused by abraded or deformed bladders. They also enhance the useful life of the bladder reducing the cost of tire curing.

摘要： Disclosed are expandable bladders for use in curing presses for rubber compositions such as pneumatic tires. The bladders are a crosslinked elastomer comprising an isobutylene rubbery polymer. The bladder composition includes alkylphenoxypoly(alkyleneoxy)-alkanol which improves the release characteristics of the cured bladder from a tire innerliner cured in contact with said bladder. The improved release characteristics allow rubber compositions such as tires to be molded with fewer defects caused during release of the bladder from the tires or caused by abraded or deformed bladders. The use of alkylphenoxypoly(alkyleneoxy)alkanol also increases the useful life time of the bladder allowing more tires to be cured without changing bladders.

摘要： In a tire having a tread with cap/base construction, a regulated amount of partially crosslinked natural rubber in a tire tread compound increases the uncured ("green") stiffness, tensile strength and tear resistance of a green compound used for the base without adversely affecting physical properties of the tread after it is cured. Such green stiffness is particularly useful in the construction of a tread for a pneumatic tire, which tread is of cap/base construction because stiffness provides requisite dimensional stability of both cap and base (in the tread) during the curing of the tire. The amount of partially crosslinked natural rubber used in a tread compound depends upon the extent of crosslinking in the natural rubber, the non-crosslinked remainder being virgin latex.

摘要： A tire tread may be formed by simultaneously extruding a tread cap formed of a first material and a tread base formed of a second material having a substantially different stiffness property than the first material. One tread element may have a strip of the second material extending from the tread base into the tread cap and, a second tread element may also have a strip of the second material extending from the tread base into the tread cap.

摘要： The subject invention is directed towards tire components which are comprised of rubber compositions which are comprised of (1) about 2 phr to about 45 phr of a trans-1,4-isoprene-butadiene copolymer which has about 4 weight percent to about 16 weight percent butadiene repeat units and from about 84 weight percent to about 96 weight percent isoprene repeat units, wherein the trans-1,4-isoprene-butadiene copolymer has a Mooney ML 1+4 viscosity which is within the range of about 35 to about 80; and (2) about 55 phr to about 98 phr of at least one other elastomer, preferably a diene based elastomer. The most preferred tire components are those which contain cord reinforcements and require adequate green strength to enhance the tire building and shaping process to maintain cord integrity in the final cured tire.

摘要： The invention relates to a tire having a rubber tread comprised of cap/base construction where the tread outer cap rubber layer contains the running surface of the tread and the tread base rubber layer underlies the tread cap layer wherein the base layer provides a transition zone between the tread cap layer and the remainder of the tire carcass and is not intended to be ground-contacting. For this invention, the tread base rubber layer is comprised of three distinct zones, namely a circumferential annular central rubber zone positioned between two lateral annular rubber zones. In one aspect, the rubber tread cap layer and zoned rubber tread base layer are co-extruded together to form an integral tread rubber composite.
