C5 Hydrogenated Hydrocarbon Resins
Quick Detail
- Minimum order:1
Specifications
PRETACK PA-95 is an aromatic modified C5 hydrocarbon resin with a narrow molecular weight distribution. It is odor improved grade with low odor, low wax cloud point. Its specific degree of modification provides an excellent compatibility with SBS, SIS and EVA polymers as well as with natural tackifier resins (like terpene,rosin and its derivatives). It has high aromatic content, especially suitable for application in SBS system Adhesives.
Key Characteristics:
Good compatibility with SBS, SIS, EVA and other polymers
Low Wax Cloud Point
Good thermal resistance
Low VOC and low odor

STORAGE
Inside storage is recommended and keep at temperature not exceeding 30oC. Pelletized forms of resins may block or lump in hot weather climates or if stored near heat sources. Resins are prone to gradual oxidation, some more so than others. This could result in darkening and/or it could have an adverse effect on the solubility of the resin in organic solvents or on its compatibility with polymers.
