Характеристики

SIS (Styrene-Isoprene-Styrene) is a kind of thermoplastic elastomer that is made of styrene and isoprene as raw materials and is worthy of anionic polymerization. It has better performance than SBS.  SIS modulus is low, easy to produce viscosity, low melt viscosity, the product has good flexibility, strong viscosity, and can associate with many tackifiers and plasticizers to obtain a good performance instant tackifier. In recent years, it has become the most common  The base polymer of the adhesive used is an important variety in hot melt adhesives and pressure sensitive adhesives.

 

KRATON D-1163P is made by copolymerization of styrene and isoprene. It is a linear thermoplastic rubber elastomer with 15% styrene content and 38% diblock ratio.  KRATON D-1163P is a dense particle, currently supplied by Japan.

 

Thermoplastic styrene butadiene rubber SIS is a block copolymer of styrene and isoprene-styrene. It is a new type of thermoplastic elastomer. SIS has thermoplasticity, high elasticity, low melt index and low solution viscosity. It is compatible with tackifying resin.  It has good capacity and is widely used in adhesives, coatings, plastic modification and other fields.  More hot-melt pressure-sensitive adhesives are used in packaging tapes, women’s sanitary napkins, diapers, double-sided tape, eyebrow tape and labels.

 

SIS has the characteristics of thermoplasticity, high elasticity, low melt index, low solution viscosity, and good compatibility with tackifying resins. It is widely used in adhesives, coatings, plastics and asphalt, etc., and can be used to prepare packaging bags and sanitary napkins.  , Diapers, double-sided tape and labels.

 

The product is mainly used in packaging bags, medical fields, women’s sanitary napkins, double-sided tapes and oil-resistant labels, etc.; commonly used in adhesives, sealing materials, shoe materials, coatings, wire and cable sheaths, sealing rubber, general daily necessities, medical or food materials  Molding, jelly candles, transparent candles, etc., can also be used as a solvent for engineering plastics.  In addition, it is the main raw material for the preparation of hot melt pressure sensitive adhesives.  Used in the soles of tires to help prevent slippage in rainy weather and improve safety.  It has both rubber and plastic properties, and its notable feature is strong adhesion.  SIS is the main raw material for hot-melt pressure-sensitive adhesives, coatings, and solvent-based adhesives.
