Orthotics & Prosthetics

WACKER RTV-2 Systems Make All the Difference
ELASTOSIL® P and SILPURAN® room-temperature-vulcanizing (RTV) silicone elastomers and gels are specially designed to meet specific prosthetic and orthotic demands. Orthotics focus on properties such the ability to cushion shock and vibration, and to apply gentle, comfortable compression. Prosthetics is a highly sensitive area of application. The aim is to make prostheses and epitheses that fit perfectly, are comfortable to wear, and are barely noticeable.
ELASTOSIL® P and SILPURAN®’s exceptional set of properties allow customized production of:
- Orthotic pelottes/pads
- Insoles, shoe orthotics
- Heel cushions, toe spacers, toe caps
- Anti-decubitus mats
- Aesthetic and functional finger, hand and partial-foot prostheses
- Epitheses
- Orthoses
- Liners
- External mammary prostheses
Benefits of ELASTOSIL® P and SILPURAN® silicone elastomers:
- Biocompatibility
- Durability: low surface tension, thermal stability and chemical stability
- Good resistance to a large number of solvents and chemicals
- No organic plasticizers involved
- Sterilizable for single and repeated use (sterilizable with steam, ethylene oxide, electron beams and γ-rays)
- The excellent mechanical properties are highly resistant to aging, weathering, heat and radiation
- Silicones do not support microbial growth (hydrophobic)
- Easy processing due to low viscosity and good mixing characteristics
- RTV-2 silicone rubber systems do not release any by-products on curing
- Broad hardness range
- High degree of comfort for wearer; breathability
