Naphtha (petroleum) light steam-cracked

Naphtha (petroleum) light steam-cracked (CAS 68478-07-9) is a complex hydrocarbon stream derived from steam cracking of petroleum fractions. Also marketed as Escorez 569 and commercially processed into piperylene concentrate polymerized resin.

Where is Naphtha (petroleum) light steam-cracked used?

• Hydrocarbon resin production: feedstock
• Adhesives and sealants: polymerized grades deliver tack and cohesion
• Hot-melt and pressure-sensitive adhesives: peel strength
• Rubber: improves processability and green strength in tire and technical rubber articles
• Coatings: adjusts viscosity and film-forming behavior in solvent-borne industrial coatings
• Plastics modification: processing aid and compatibilizer in polyolefin blends where melt flow needs to be tuned
• It also serves as a tackifying and rheology-modifying component in polymer-based formulations.

Good to know: Grades are differentiated by softening point, molecular weight distribution, and aromatic content; resin compatibility is a key selection factor in rubber.
