Hydrocarbon Resin

I. Product Overview Hydrocarbon resins are thermoplastic resins polymerized from petroleum hydrocarbon monomers, belonging to low-molecular-weight polymers. They are classified into aliphatic, aromatic, etc., based on raw materials, and are widely used as tackifiers or modifiers. II. Key Features · Good compatibility: High adaptability with substrates like rubber and plastics, easy to mix and process. · Excellent tackiness: Enhances the bonding strength of products, with stable low-temperature tackiness. · Good weather resistance: Resistant to thermal-oxidative aging, adaptable to a wide temperature range (-30℃ to 120℃). III. Common Specifications · Types: C5 aliphatic (low color number), C9 aromatic (high softening point), C5/C9 copolymer. · Softening point: 60-160℃ (selected by application; 80-120℃ for hot melt adhesives). · Color number (Gardner): 1-10 (smaller value indicates lighter color). · Molecular weight: 500-3000 (affects tackiness and fluidity). IV. Typical Applications · Adhesives (hot melt adhesives, pressure-sensitive adhesives), rubber products (tires, seals). · Coatings (road marking paints, anti-corrosion paints), printing inks.
