Styrene Isoprene Styrene used in many
industry applications

Styrene Isoprene Styrene (SIS) is a thermoplastic elastomer with various industrial applications. Here are some of its uses:

  1. Adhesives and Sealants: SIS is used as a base polymer in pressure-sensitive adhesives (PSAs) and hot-melt adhesives due to its excellent tackiness, flexibility, and adhesive strength.
  2. Hygiene Products: It is used in the manufacturing of elastic components in hygiene products such as diapers, sanitary napkins, and adult incontinence products.
  3. Footwear and Apparel: SIS is used in the production of shoe soles, sports shoe components, and elastic fabrics in apparel for its resilience, comfort, and durability.
  4. Medical Devices: It is used in medical applications such as prosthetics, medical tubing, and surgical drapes due to its biocompatibility and resistance to sterilization methods.
  5. Packaging: SIS is used in flexible packaging applications as a sealant layer in pouches, sachets, and wrappers to provide heat resistance, seal strength, and barrier properties.
  6. Automotive Industry: It is used in automotive components such as gaskets, weatherstripping, and vibration dampers for its resilience to weather conditions and mechanical stress.
  7. Electronics: SIS is used in electronic components and consumer electronics for vibration dampening, insulation, and shock absorption properties.
  8. Construction: It is used in construction applications such as roofing membranes, sealants, and waterproof coatings due to its flexibility and resistance to weathering.
  9. Sports Equipment: SIS is used in the manufacture of sports equipment such as grips, padding, and protective gear for its impact resistance and cushioning properties.
  10. Industrial Coatings: It is used as a component in coatings and paints to improve flexibility, adhesion, and impact resistance.
