Â
HITACK GL-140Â is a low molecular weight
thermoplastic aromatic resin obtained from petroleum- derived
monomers. It is odor improved grade with low odor and low VOC,
good compatibility with other resins and polymers. This grade
is mainly used in adhesives, esp. EVA based Hot Melt
Adhesives.Â
Â
Key Characteristics:
• Good compatibility with EVA,SBS
• Mutual solubility
• Good thermal resistance
• Low VOC and low odor
• Water resistance
• Insulation and excellent chemical stability.

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.Â
