PRETACK PL-91 is a light colored, premium, aliphatic
hydrocarbon resin with a narrow molecular weight distribution. It
is odor improved grade with low odor, low wax cloud point. It has
excellent compatibility with EVA, APP, APAO, styrene block polymers
(such as SIS, SEBS, and SBS), Natural Rubber and many kinds of
synthetic rubbers, as well as natural tackifier resins (such as
terpene, colophonyl and its derivatives).This grade provides good
adhesive capability, excellent aging stability and light color in
Hot Melt Pressure Sensitive adhesive and Hot Melt Adhesives
applications.
Key Characteristics:
• Good compatibility with EVA, SIS, 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.
