C5 hydrocarbon resin is made from C5 distillate cracked by ethylene as raw material,Petroleum Resin and is produced by cationic polymerization of diene and monoene in C5 component.
Petroleum resin is a kind of thermoplastic resin produced by cracking C5 olefins in the by-product of ethylene plant through pretreatment, polymerization,Petroleum Resin flash evaporation and other processes.
Hot melt adhesives are gaining in popularity due primarily to their lower processing costs and regulatory requirements.
The cracked C9 fraction mainly contains unsaturated aromatic hydrocarbon compounds such as vinyl toluene, indene, methylstyrene,Petroleum Resin etc.
Petroleum resin is a kind of thermoplastic resin,which is byproducts in oil cracking by the process of pretreatment, polymerization, distillation，etc.,
Hydrocarbon resins, which are defined as low molecular weight, amorphous, and thermoplastic polymers, are widely used as tackifiers for various types of adhesives, as processing aids in rubber compounds, and as modifiers for paint and ink products, and for use in plastics polymers such as isotactic polypropylene.
It's not that much of a stretch to say hot melt adhesives bind the galaxy together. Okay, maybe it is a stretch. But it is a fact that hot melt adhesives, also known as HMAs, have been used across a broad range of substrates and applications.
At present C5 Petroleum resins,industrially also known as C5 Aliphatic Hydrocarbon Resins and C5 Hydrocarbon Resins, is playing gradually more and more important role as Tackifying resins in the adhesive and sealant industry, especially in the application of hot melt adhesive and pressure sensitive adhesive.
