Medical grade silicone gels providing optimal elasticity and rebound for breast forms and cushions

Crosslinked silicone gels have been used for decades to manufacture breast forms, also called external breast prostheses. These devices are prescribed to women who underwent a mastectomy following breast cancer. The ideal external breast prostheses should be comfortable to wear and provide a realistic life-like feel.

Elkem Silicones provides a wide range of medical grade silicone gels to answer the needs of breast form manufacturers and increase the quality of life for the patient.

Elkem Silicones’ Silbione™ RT Gels provides the following features : 

  • Biocompatible according to ISO 10993
  • Wide range of penetration (softness) and damping properties
  • Lightweight grades (down to 0.6 density) for an increased comfort
  • Primers available for a defect-free adhesion on Polyurthane film

Our range of Silbione™ RT Gels used in the manufacturing of breast prosthesis includes:

The unique viscoelastic properties of silicone gels make them also a material of choice for the manufacturing of patient positioning and pressure care products. These cushion-like devices are used to position and redistribute the weight of the patient during their stay in the Operating Room, in order to prevent the formation of decubitus and pressure sores. They are placed below critical pressure points like the head, elbow, feel & foot of the patient and should be safe for the patient and easy to use by the Operating Room staff.

Elkem Silicones has worked with industry leaders to develop our Silbione™ RT Gels that are used in the manufacturing of cushions and pressure-relieving products:
