Description

Steam-Cracked Petroleum Distillates/ Naphthenates Polymers are a specialized class of hydrocarbon-based polymers derived from steam-cracked petroleum fractions and naphthenic acids. These versatile materials serve as crucial performance additives and intermediates, valued for their ability to modify viscosity, enhance dispersion, and act as tackifiers or compatibilizers. They are essential for formulators and manufacturers in the adhesives, sealants, coatings, and rubber industries seeking to optimize product performance and processing characteristics.

Application

• Adhesive & Sealant Formulation: Acts as a tackifier and viscosity modifier in hot-melt, pressure-sensitive, and construction adhesives.
• Rubber & Tire Manufacturing: Used as a processing aid and softener to improve compound plasticity and filler dispersion.
• Industrial Coatings & Inks: Functions as a rheology modifier and dispersing agent to control flow and pigment stability.
• Polymer Modification: Serves as a compatibilizer and plasticizer in various polymer blends and compounds.
• Lubricant & Grease Additives: Employed to enhance the tackiness and adhesive properties of specialized lubricating greases.
• Foundry & Mold Release Agents: A key component in formulations for sand core binders and release coatings.

Quality Control

Our Steam-Cracked Petroleum Distillates/ Naphthenates Polymers are manufactured under a rigorous quality management system. Each batch is tested against key parameters including softening point, color, viscosity, and acid number to ensure consistent performance and batch-to-batch reliability. Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at ambient temperatures (typically 15-25°C). Keep away from strong oxidizing agents and heat sources to maintain product integrity.
