Hydrocarbon resin C5

Hydrocarbon Resin C5（Aliphatic C5 Resin）

C5 Resin (C5 hydrocarbon resin) is a low-molecular-weight, aliphatic thermoplastic obtained by cationic polymerization of the C5 fraction (isoprene, piperylene, cyclopentadiene, etc.) produced during petroleum cracking. It comes as pale-yellow to water-white granules with a softening point of 80–110 °C and is odorless and non-toxic.

Key features:  

- Excellent compatibility with natural rubber, SIS/SBS, EVA, APAO and other elastomers  

- Markedly boosts tack, peel strength and low-temperature performance  

- Resistant to acids, alkalis and water; good electrical insulation  

Main applications: 

1. Hot-melt adhesives (packaging, hygiene, labels) – provides tack and open time  

2. Pressure-sensitive adhesives (tapes, stickers) – adjusts peel force  

3. Road-marking paints – improves adhesion of glass beads and wear resistance  

4. Tires and rubber goods – acts as tackifier/plasticizer  

5. Construction sealants and waterproof membranes – enhances flexibility and adhesion  

In short: C5 resin is the “tack catalyst” that makes adhesives, paints and rubber stick faster, stronger and longer.
