JT-6421 a modified thermoplastic alkyl phenol-formaldehyde resin of high performance as a substitute for alkyl phenol acetylene super tackifying resin. This product shows advantages of tackiness retention of semi products over long-term or under humid heat conditions which favors building of tires and other rubber articles. JT-6421 provides lower dynamic heat-generation for vulcanizates than general p-t-Butyl or p-t-Octyl phenolic resins do which can decrease heat-generation in tires and industrial rubber goods, prolong their life length.
As dispersing and super tackifying resin, JT-6421 is suited to various rubbers in production of high performance tires and diversified technical rubber articles such as conveyor belts, V-belts, industrial hoses, rubber plates, roll coverings, cables, lining materials, retread materials, etc.
