C9 cold polymerization petroleum resin

Cold Polymerized Carbon Nine Petroleum Resin

I. Basic Characteristics

Physical and Chemical Parameters

Appearance and Form: It is a low molecular weight thermoplastic aromatic petroleum resin, made from C9 fraction produced as a byproduct of ethylene plant, and the product appearance is a light yellow transparent granular solid.

Softening Point: The typical range is 100-140℃, and the specific value can be adjusted through the thermal polymerization process. High softening point models (such as 140℃) are suitable for high temperature environments. Molecular Characteristics: The molecular weight is between 300-3000, there is no polar group, it is resistant to acid, alkali and water, and it is soluble in solvents such as toluene and xylene.

Product Characteristics:

Good solubility;

Good waterproof and insulation;

Good chemical stability under acid and alkali conditions.

Performance Advantages

Adhesion: It has good compatibility with rubbers such as SBR and NR, and significantly improves the adhesion between the rubber and the substrate. Stability: The thermal stability reaches 180℃ (short-term tolerance), and it is not easy to yellow after long-term use, and is suitable for outdoor scenes.

II. Core Application Areas

Used for varnish. Self-spray paint. Alkyd resin blended paint. Printing ink. Adhesive, asphalt modification, anticorrosive paint, industrial coating
