Petroleum Resin C5 (CAS No.: 64742-16-1) is a type of aliphatic petroleum resin. Unlike previous phenolic resins, it emphasizes high compatibility and easy processing, and is suitable for various industrial scenarios. It is produced from the C5 fraction obtained from petroleum cracking, through a polymerization process. It is a light yellow granule with no obvious irritating odor. It has excellent compatibility and can perfectly match SIS, SIBS, SBS block copolymers, and EVA copolymers, and is widely used in hot melt adhesives, pressure-sensitive adhesives, rubber, coatings, and other fields.

FAQ
Q: Where is C5 petroleum resin mainly used?
A: It is mainly used in fields such as Hot Melt Adhesives, Adhesives, Pressure Sensitive Adhesives, Rubbers, and Paints.
Q: Is there any difference compared to C9 petroleum resin?
A: Yes, there is a difference. C9 petroleum resin is a thermosetting petroleum resin produced by pressure heat polymerization technology, while C5 is an aliphatic resin, which has better compatibility and processing properties.
Q: What should be noted during storage?
A: Store it sealed in a cool and dry place, away from high temperatures and fire sources, and avoid softening and sticking together. The shelf life is 12 months.
