Used in:

1、In the industry of adhesive and sealant, petroleum resin plays an important role as tie resin. PR-A series petroleum resins are suitable to the petroleum resin of hot-melt adhesive and contact adhesive. They have good compatibility with SIS, SBS, SEBS, SEPS, natural rubber, synthetic rubber and EVA etc..

The characteristics of RK-A1090, A1095, A1100, A1105, A1110, A1115 petroleum resin in adhesive:

· Good fluidity.

· Good viscosity.

· Excellent ageing resistance.

· Light color.

· Transparent, low odor, low volatile matter.

2、RK-A1090, RK-A1095, RK-A1100，RK-1105 petroleum resin are a kind of petroleum resin widely used in tyre rubber mixing. It has good compatibility with natural rubber( NR), synthetic rubber, polyethylene, polypropylene, SIS, SEBS, EVA etc.. It is also used as tackifier,reinforcing agent,softener and filler etc.in rubber synthetic.

Properties in rubber synthetic:

· Excellent tackify property.

· Improve extensibility and spalling resistance.

· Cure time and the physical properties after sulfuration are not affected.

· Avoid adhesive capacity to processing machinery.

· Help filling material distribute evenly.

· Proper color.

Application field recommended:hot-melt adhesive and contact adhesive，or: mixing of tyre rubber and Other rubber products, such as tread, shoes heel, floor, belt etc.
