Chemical element structure model of petroleum resin:
Petroleum resin production application is C9 petroleum resin and C5 petroleum resin at most.
C5 petroleum resin
C5 petroleum resin is gradually replacing natural resin viscosifier (rosin and terpene resin) due to its characteristics of high peel adhesion strength, fast adhesion, stable adhesion, moderate melt viscosity, good heat resistance, good compatibility with high polymer matrix and low price.
Characteristics of C5 petroleum resin in hot melt adhesive: good fluidity, can improve the wettability of the main data, good viscosity, with outstanding initial viscosity.
Excellent aging resistance, light color, transparent, low odor, low volatile matter.
In hot melt adhesive, ZC - 1288D series can be used as viscosifier alone or mixed with other viscosifiers to improve some properties of hot melt adhesive.
