Petroleum hydrocarbon resin

Petroleum hydrocarbon resin (CAS 68527-25-3) is a thermoplastic polymer produced from steam-cracked aromatic and aliphatic petroleum fractions, including piperylene concentrates.

Where is Petroleum hydrocarbon resin used?

• Adhesives: tackifier, compatibilizer and rheology modifier
• Hot-melt and pressure-sensitive adhesives: boosts tack and peel strength in packaging tapes, labels and assembly applications
• Rubber: improves processability and reinforces green strength in tire treads, belts and molded goods
• Coatings: modifies viscosity and film-forming behavior for industrial application and leveling profiles
• Sealants and elastomers: controls flow and extends open time in construction and automotive sealing compounds
• It provides stability and adhesion for industrial bonding solutions.

Commercial specifications

• Softening point grades typically 80°C to 140°C
• Technical grade standard; specifications vary by aromatic content, color (Gardner scale) and molecular weight distribution
• Bulk and bagged formats commercially available
