Petroleum Resin
C5 & C9 Petroleum Resin Manufacturer and Supplier
Hydrocarbon petroleum resins are low-molecular-weight thermoplastic tackifiers synthesized via catalytic or thermal polymerization of cracked petroleum fractions. Depending on the feedstock streams (aliphatic C5 piperylene/isoprene, aromatic C9 vinyltoluene/indene, or blended cuts), these resins impart tack, wettability, adhesion strength, and water resistance across diverse polymer matrices.
Our manufacturing facility operates automated continuously stirred tank reactors (CSTR) and high-efficiency vacuum stripping columns. This process strips residual volatile organic compounds (VOCs) and low-boiling monomers, yielding resins with low odor and thermal color stability. Quality validation includes automated Ring & Ball softening point analysis, spectrophotometric color testing, and Gas Chromatography (GC) residual monomer determination on every production batch.
Product Types & Grades
C5 Aliphatic Petroleum Resin
C5 petroleum resin is primarily used as a tackifying and formulation component in adhesive and rubber applications.
Its listed compatibility with SIS, SIBS, SBS, and EVA makes it relevant to polymer-based adhesive systems. Buyers should evaluate tack, peel adhesion, holding power, and melt behavior in their own formulations.
C9 Aromatic Petroleum Resin
C9 petroleum resin is produced using pressure thermal polymerization technology. Different softening point grades are available for applications requiring different thermal and formulation characteristics.

Applications
Hot Melt & Pressure Sensitive Adhesives (HMA/PSA)
C5 and hydrogenated resins act as primary tackifiers in EVA, SIS, and SBS formulations for packaging tapes, sanitary non-wovens, woodworking, and label adhesives.
Tire and Industrial Rubber Compounding
C9 and C5/C9 copolymer resins increase green tack during multi-layer assembly, improve silica/carbon black filler dispersion, and lower processing torque without reducing cured modulus.
Road Marking Paints
C5 aliphatic resins serve as the binder matrix in thermoplastic road formulations, providing heat resistance, rapid setting, and surface adhesion to asphalt and concrete.
Printing Inks & Coatings
C9 aromatic resins enhance binder drying speed, gloss level, and pigment wetting in gravure, offset printing inks, and alkyd-based protective coatings.
Petroleum resin performance depends on both the resin specification and the formulation in which it is used. The following parameters are relevant to raw material evaluation:
Softening point: Helps determine the resin's thermal behavior and suitability for the intended processing conditions.
Color: Important for light-colored adhesives, coatings, and appearance-sensitive products.
Acid value: Supports evaluation of resin chemistry and consistency between batches.
Ash content: Indicates inorganic residue in the resin.
Melt viscosity: Helps assess resin flow and processing behavior at the specified temperature.
Heat stability: Color change after heating provides a useful indicator for applications involving elevated processing temperatures.
Manufacturing & Quality Infrastructure
For incoming quality control, buyers can request a batch COA and compare the shipment results with the agreed specification. TDS and SDS should also be reviewed before production trials and bulk procurement.
Great Bridge Chemical reports an ISO 9001:2015 quality management system. Buyers can request the relevant certificate and confirm its validity and scope during supplier qualification.

Packaging & Supply
Standard Packaging
25 kg multi-layer paper bags with inner PE liners; packed on 1,000 kg shrink-wrapped wooden pallets (20 metric tons per 20ft FCL).
500 kg or 1,000 kg polypropylene bulk bags (FIBC) with discharge spouts.
Storage & Handling
Store in dry, cool, well-ventilated indoor facilities below 30 deg C to prevent blocking or agglomeration during storage. Avoid direct sunlight and moisture. Shelf life is 12 months from production date in sealed original containers.
Logistics & Lead Time
Standard C5, C9, and hydrogenated grades are maintained in regional warehouse inventory. Standard FCL shipments dispatch within 14 to 21 days from order confirmation.
