  • BISCO® Medical Silicones
  • PORON Medical® Urethanes
  • Crosslinked Polyethylene


Material Details:

BISCO Medical Silicones and PORON Medical Urethanes are fungal resistant, PVC, latex and solvent free, biocompatible, and pressure relieving while offering lasting comfort and durability. The range of materials have passed biocompatability analysis for cytoxicity, primary skin irritation, and dermal sensitization for surface device contact with intact skin per ISO 10993-1 and FDA G95-1 guidelines.

BISCO® Medical Silicones offer long-term comfort and durability - As both open and closed cell structures, they maintain their dimensional stability even when exposed to dry heat, steam electron beam, ethylene oxide, alcohol and gamma radiation. BISCO Medical Silicones are ideal for body contact devices in life-saving procedures, imaging (sonography surface), and sterile surfaces ("cleanroom" surfaces).

PORON Medical® Urethanes are flexible, resistant to collapse, and possess excellent shock-absorption capabilities – These urethanes are medium density and open celled, breathable and fungal resistant, and offer lasting comfort, durability, and biocompatibility, making them ideal for cushioning applications such as protective garments, prosthetic cushions and pressure point pads. In monitor applications, these foams may be used to hold monitoring devices to the body and in oxygen sensor pads. They can also be used in appendage wraps and monitor grips where soft restraint is required. They are offered in three grades:

  • PORON Medical Soft Cushioning and Soft Supporting - providing long-term comfort; compression-set resistant, and fungal resistant.
  • PORON Medical Firm Energy Absorbing - offers high-energy return and excellent impact absorption.
  • PORON Medical Slow Recovery Custom Contouring and Fit Accomodating - offers controlled energy return resulting in a customized fit during each use. Applications include:
    • medical grounding pads
    • single- and double-sided tapes
    • sealing gaskets
    • self-stick gadgets from air fresheners to towel racks
    • incontinence guards
    • suture holders
