Characteristics of C5 petroleum resin

C5 petroleum resin, also known as C5 petroleum resin, has occupied an important position as a tackifying resin. Among them, the most used are hot melt adhesives and pressure sensitive adhesives, rubber tires and other fields. Petroleum resin is a petroleum resin suitable for hot melt adhesives, pressure sensitive adhesives and rubber tires. They have good compatibility with SIS, SBS, SEBS, SEPS and other styrene polymers, natural rubber, synthetic rubber and EVA, etc., and compatibility with natural tackifying resins (terpenes, rosin and their derivatives) It is also good, it can improve the various properties of the adhesive to varying degrees. In recent years, petroleum resins have gradually begun to gradually adopt the characteristics of high peeling and bonding strength, good fast tack, stable bonding performance, moderate melt viscosity, good heat resistance, good compatibility with polymer matrix, and low price. Replace natural tackifying resin and occupy a prominent position.

The characteristics of C5 petroleum resin in adhesive system:

Good fluidity, can improve the wettability of the main material.

Good viscosity, with outstanding initial adhesion performance.

Excellent aging resistance.

Cohesive strength and peel strength reach the best balance.

Light color.

Transparent, low odor, low volatile matter.

The characteristics of carbon five petroleum resin in the tire rubber field:

Has excellent viscosity increasing

In the process of processing, it can play a role of softening and strengthening, and improve the stretch and peel resistance.

Significantly improve the viscosity, but does not affect the curing time and physical properties after curing.

Avoid adhesion to processing machinery.

Help the filling material to be distributed evenly.
