ABSTRACT:
Naturally occurring dark, tacky, low softening thermoplastic resins of low acid number can be used as substitutes for all or part of the non-elastomeric petroleum-derived components of rubber stocks used for manufacture of tires and other rubber articles. For example, such resins can be used to replace petroleum-derived process oils or resins, or both, used in making tires. The resins, which are derived from wood, are low softening thermoplastic resins characterized by having about 15-30% unsaponifiables, 3-20% rosin acids, 3-15% fatty acids and 5-15% sterols. A typical useful resin is commerically available under the name Pamak TP.
