C5/C9 Copolymer Hydrocarbon Resin from China Suppliers - High-Performance Tackifying Resin Factory
Product Parameter
C5/C9 copolymer hydrocarbon resin can be used as a tackifying resin and applied in high-performance formulations of hot-melt adhesives and pressure-sensitive adhesives. Granular resin may clump or agglomerate in high-temperature climates or when placed near heat sources, so it is recommended to store it indoors and keep it at a low temperature.
| Grade | Softening Point | Color Gardner | Features | Application |
|---|---|---|---|---|
| G-90 | 85-95 | ≤5 | Light color, Low VOC | HMA, Packaging adhesive Rubber Compounding |
| G-100 | 95-105 | ≤5 | Light color, LMW | HMA, PSA, Packaging adhesive, Rubber Compounding |
| G-110 | 105-115 | ≤6 | Light color, LMW | HMA, PSA, Packaging adhesive |
| G-120 | 115-125 | ≤6 | High softening point | HMA, PSA, Packaging adhesive |
Frequently Asked Questions
What are the primary uses for C5/C9 copolymer hydrocarbon resin?
It is primarily used as a tackifying resin in high-performance hot-melt adhesives (HMA), pressure-sensitive adhesives (PSA), packaging adhesives, and rubber compounding.
Why is storage temperature critical for this resin?
Granular resin is sensitive to heat. In high-temperature climates or near heat sources, the granules may clump or agglomerate, making them difficult to process. Indoor, cool storage is essential.
What does "Low VOC" mean for the G-90 grade?
Low VOC (Volatile Organic Compounds) indicates that the resin releases fewer harmful emissions during processing and application, making it suitable for environmentally sensitive packaging and indoor use.
How does the softening point vary among the G-series grades?
The softening point ranges from 85°C (G-90) up to 125°C (G-120), allowing manufacturers to choose a grade that matches the specific thermal requirements of their adhesive formulation.
Are these resins compatible with rubber compounding?
Yes, specifically grades like G-90 and G-100 are frequently used in rubber compounding to improve processability and tack properties.
What is the significance of the Gardner Color scale in these parameters?
The Gardner Color scale (≤5 or ≤6) indicates the resin's light color and high clarity, which is vital for applications where the final appearance of the adhesive must be transparent or near-colorless.
