C5/C9 Copolymer Hydrocarbon Resin from China Suppliers - High-Performance Tackifying Resin Factory
Product Parameter
C5/C9 copolymer hydrocarbon resin is a versatile tackifying resin specifically engineered for high-performance formulations in hot-melt adhesives (HMA) and pressure-sensitive adhesives (PSA). Its unique chemical structure ensures excellent compatibility and bonding strength.
Storage Notice: Granular resin may clump or agglomerate in high-temperature climates or when placed near heat sources. It is highly recommended to store the material indoors and maintain a consistently low temperature to ensure product integrity.

Frequently Asked Questions
What are the primary uses for C5/C9 copolymer hydrocarbon resin?
It is primarily used as a tackifier in high-performance hot-melt adhesives (HMA), pressure-sensitive adhesives (PSA), packaging adhesives, and rubber compounding to improve bonding and stability.
How does the softening point affect the application?
The softening point, ranging from 85°C to 125°C across different grades, determines the heat resistance and setting speed of the adhesive. Higher softening points like G-120 are ideal for applications requiring greater thermal stability.
Why is the Gardner Color value important?
A lower Gardner Color value (such as ≤5) indicates a lighter, more transparent resin. This is critical for high-end packaging and adhesives where the appearance of the final product must remain clean and clear.
Can C5/C9 resin be used in rubber compounding?
Yes, specifically grades like G-90 and G-100 are excellent for rubber compounding, providing improved processability and tackifying properties to the rubber mix.
What is the best way to prevent resin clumping during storage?
To prevent agglomeration, the resin should be stored in a cool, dry indoor environment. It should be kept away from direct sunlight, heat sources, and high-temperature climates.
What does "LMW" stand for in the product features?
LMW stands for Low Molecular Weight. Resins with LMW generally offer better compatibility with various polymers and can improve the flow and wetting properties of the adhesive.
