As a tackifying resin, C5 petroleum resin has occupied an important position in the adhesive and sealant industry. C5 petroleum resin is a petroleum resin suitable for hot-melt adhesive and pressure-sensitive adhesive. They have good compatibility with styrene polymers such as sis, SBS, SEBS and SEPs, rubber, synthetic rubber and EVA. In recent years, C5 petroleum resin has gradually replaced resin tackifier because of its high peel bonding strength, fast adhesion, stable bonding performance, moderate melt viscosity, good heat resistance, good compatibility with high polymer matrix and low price.

Characteristic analysis:

1. Good adhesion and outstanding initial adhesion

2. Excellent aging resistance

3. Light color

4. Transparent, low odor, low volatile matter

5. In hot melt adhesive, PHT can be used alone ®- As a tackifying resin, series a can also be mixed with other tackifying resins to improve some properties of hot melt adhesive.

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