Use:
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 PR-A3090, A1095, A2100, A1101, A2110, A2120 petroleum resin in hot-melt adhesive:
· Good fluidity.
· Good viscosity.
· Excellent ageing resistance.
· Light color.
· Transparent, low odor, low volatile matter.
PR-A series can be separately used as tie resin in hot-melt adhesive or mixed with other tie resin.
Application field recommended:hot-melt adhesive.
Other use:hot-melt contact adhesive, solvent contact adhesive.
The properties of PR-A1101, PR-A2110, PR-A2120 and PR-A1100 petroleum resin in solvent contact adhesive:
PR-A1101
·Keep the balance of cohesvie strength and peeling strength. · Excellent ageing resistance.
· Light color.
PR-A2110, PR-A2120
· Improve peeling strength and cohesvie strength a lot.
· Excellent ageing resistance.
· Light color.
PR-A1100
· High peeling strength with the guarantee of initial viscosity and cohesvie strength. · Excellent ageing resistance.
Different solvent contact adhesives can be got according to different tie resins and different proportion of PR tie resins.
Application field recommended:solvent rubber contact adhesive.
Other use:hot-melt adhesive, hot-melt contact adhesive.
The characteristics of PR-A3090, A1095, A2100, A1101, A2110 petroleum resin in hot-melt contact adhesive:
PR-A3090
· Has excellent initial viscosity, keeping the balance of initial viscosity and cohesvie strength. · Comparatively good fluidity.
· Light color.
PR- A1101
· Keeps the balance of initial viscosity, cohesvie strength and peeling strength. · Excellent ageing resistance.
· Light color.
PR-A2110
· keeps the balance of initial viscosity and cohesvie strength. · Good fluidity.
· Excellent ageing resistance.
· Low volatile matter, low odor.
PR-A1095
· Excellent initial viscosity. · Excellent ageing resistance.
· Light color.
Different hot-melt contact adhesives can be got according to different tie resins and different proportion of PR tie resins.
Application field recommended:hot-melt contact adhesive.
Other use :hot-melt adhesive, solvent contact adhesive.
