Best Quality SIS (Styrene Isoprene Block Copolymer) Raw Materials

SIS (Styrene Isoprene Block Copolymer)

General Description of SIS Series Products

SIS is styrene – isoprene block copolymer in the form of white porous particle or translucent compact particle, with features of good thermo-plasticity, high elasticity, good melt fluidity, good compatibility with tackifying resin, safe and non-toxic. It can be applied to the hot-melt pressure-sensitive adhesives; solvent cements, flexible printing plates, plastics and asphalt modification, and is the ideal raw materials of adhesives used to manufacture packing bags, sanitation supplies, double-sided adhesive tapes and labels.

Usage of SIS Series Products

  • SIS series products, or Styrene-Isoprene-Styrene block copolymers, find extensive applications across a wide range of industries.
  • They are commonly used as a raw material for the manufacture of hot-melt pressure-sensitive adhesives, solvent cements, flexible printing plates, plastics, and asphalt modification.
  • In addition to these applications, They are also ideal as raw materials for the production of adhesives used in manufacturing packing bags, sanitation supplies, double-sided adhesive tapes, and labels.
  • The unique properties of SIS, including good adhesive performance, high heat resistance, and excellent elasticity, make it a popular choice for a range of industrial applications.

Packaging of SIS Series Products

SIS products, or Styrene-Isoprene-Styrene block copolymers, are commonly packaged and stored in two different ways.

  • The first method is in 20kg paper-plastic packaging bags. These bags are designed to protect the SIS material from moisture, dust, and other environmental factors that may affect its quality. The combination of paper and plastic provides durability and enhances the safety of the product during transportation and storage.
  • The second method is in 520kg polypropylene container bags, which are designed for larger volumes of SIS products. These bags are made of high-quality polypropylene material and are widely used for the storage and transportation of various industrial materials. The strong and durable bags are resistant to wear and tear, ensuring that the SIS material remains safe and secure during transportation and storage. The container bags are easily stackable and easy to handle, making them a convenient option for larger volumes of SIS products.
