Alternatives to PVC for Medical Applications

Cariflex Gloves

Kraton Performance Polymers is the world's leading producer of styrenic block copolymers, or SBCs. SBCs are highly-engineered synthetic elastomers, which are used in a wide variety of products to impart clarity, flexibility, resilience, strength, durability and processability. SBCs are a fast growing subset of the broader elastomers industry. We pioneered these products over 35 years ago and offer a broad line of SBCs to customers worldwide. In addition to medical applications, our products are used in a wide variety of applications including automotive applications, numerous consumer products (diapers, tool handles, razors), tapes, labels, packaging systems, road and roofing materials, and footwear products. We offer our customers a broad portfolio of products that includes more than 100 core commercial grades of SBCs.

Our polymers offer the following:

  • USP Class VI Toxicology Requirements
  • FDA Clearance
  • Easy Processability
  • Superior Toughness
  • Clarity (pure and in blends)
  • No Plasticizers

EO, EB and gamma sterilization are possible with the neat polymers. Steam sterilization is possible when the polymers are used in combination with other polymers, or in coextrusions. Grades are offered with high resilience, low compression set, good puncture and reseal properties and with no plasticizers needed.

Kraton® G Polymers

Kraton G polymers are SBCs with a hydrogenated midblock. They are elastic and flexible with the additional benefits of enhanced oxidation and weather resistance, higher service temperatures, and increased processing stability. They provide formulation flexibility, ease of processing in commonly used thermoplastic technology, clarity in polyolefin blends, and offer such performance benefits as softtouch, improved grip, and UV stability. SEBS, SEPS, and SEP grades are also used for sealants and high performance adhesives.
