Kolon Industries SUKOREZ® SU-640 is a white thermoplastic resin obtained from the copolymerization and hydrogenation of C5 aliphatic olefin and diolefin generated in the thermal-depolymerization process of naphtha. This product offers excellent thermal stability and compatibility with various elastomers such as Ethylene-Vinyl-Acetate (EVA) and Styrene-Isoprene-Styrene copolymer (SIS) so this product is used as tackifier resin for hot melt adhesive (HMA) and hot melt pressure sensitive adhesive (HMPSA), as well as polypropylene (PP) modifier. SUKOREZ® SU-640 is water white cycloaliphatic hydrocarbon resin. The major usage are a modifier in blends with polymers for filmic application and tackifier for EVA, SIS, SEBS block copolymers, metallocene polyolefins and APAO.

Packaging & Availability

Packaging Type
Packaging and Storage


available both in big bags of 500kgs net weight and in multi-ply paper bags of 25kgs net weight.


Pelletized forms of resins may block or lump.It is recommended,

  • to store inside and keep cool condition (30℃ max / resin with softening point below 100℃ - 25℃.max)
  • not stacking pallets
  • to avoid sunlight

Especially, low softening point resins(below 100℃) has a higher possibility of blocking due to the nature of product. Therefore, we strongly recommend that keep storing in more strict conditions.

Storage & Handling

Shelf Life

The shelf life can be affected by storage and handling conditions. When products are stored in the original unopened container in an enclosed area and protected from contamination,moisture and extreme temperatures, the shelf life of SUKOREZ ® is two years from the date of manufacture . Shelf life is a guide not an absolute value , and KOLON doesn't control end uses and storage conditions at customers. Therefore, the product should be reanalyzed for properties at the end of its shelf life to see if it meets specification for use.
