Overall performance Advantages
Enhanced finish as well as adhesion
The actual branched, reduced molecular pounds framework plays a role in more powerful area connections along with adhesives, silicone, as well as films.
Improved digesting relieve
Reduce viscosity facilitates combining as well as extrusion effectiveness within plastic compounding.
Heat strength
Along with treatment factors over 100 °C, C5 resins preserve balance below warmth tension.
Visual qualities
Gentle color guarantees item visibility, advantageous within product packaging as well as obvious glues.
