Applications and benefits

Syringe tips, peristaltic tubes, seals, gaskets and grips are among the products that benefit from Santoprene thermoplastic vulcanizates. Key benefits include:

Excellent performance

  • Long-term durable sealing capabilities in harsh environments
  • Outstanding physical properties
  • High-end finished part aesthetics through aspect harmonization and excellent surface qualities

Reduced part/system costs

  • Ease of processing, which allows a broad processing window, fast cycle times and tight tolerances in part design
  • Design flexibility, which allows the combination of hard/soft materials
  • Lower scrap rates compared to thermoset rubber materials

Sustainability opportunities

  • The lower density of Santoprene TPVs compared to thermoset rubber and other thermoplastic elastomers can contribute to reduced part weight
  • Reduction in overall waste in the manufacturing process as scrap produced during processing can be recycled
  • Due to integrated manufacturing, such as multishot injection molding, chemical usage is reduced because spray coatings and adhesive application are not needed
  • Reduced manufacturing energy consumption as heat curing is not required compared to EPDM thermoset rubber
  • Less manufacturing space because typical TPV extrusion lines only need one-third of the space used by comparable EPDM thermoset lines
