2. Use
In anchoring agent and sealing agent industries, C5 petroleum resin has very important position as gluing resin. Of which hot melt adhesive and pressure sensitive adhesive are widely used.PRS®-A C5 series petroleum resin is suitable for hot melt adhesive and pressure sensitive adhesive. They have excellent compatibility with elastomers as SIS, SBS, SEBS, SEPS and also have excellent compatibility with natural rubber, synthetic rubber and EVA as well as natural adhesive resin (such as terpene, rosin and other ramifications) which ensures the improvement to each performance. Recently, C5 petroleum resin gradually take the place of natural adhesive resin (terpene and rosin) by its qualities of strong adhesive strength, quick adhesive, stability, moderate melting, anti-hotness, better compatibility with high polymers, possessing an important position.
3. Characteristics of PRS®-A1085, A1090,  A1095, A1100 of C5 petroleum resin in the hot melt adhesive:
 Better fluidity and can improve the wetting of principal part materials.
Have better glutinosity and sistinguished initial adhibiting performance
Excellent anti-aging property
Light color
Transparent, lwo smell and low volatileness
In the hot melt adhesive, PRS®-A series can be used as the anchoring agent resin and also can be mixed with other anchoring resin to improve certain features of hot melt adhesive.
Recommended application fields: hot melt adhesive
Other applications: Hot melt pressure-sensitive adhesive, impregnant pressure-sensitive adhesive |
