HTV Silicone (High Temperature Vulcanized Silicone)
What is HTV Silicone?
HTV Silicone is a high-performance elastomer that is cured under elevated temperatures, resulting in a highly uniform, mechanically stable and durable material structure. Compared to room-temperature vulcanizing silicones, HTV Silicone offers superior strength, elasticity retention and long-term reliability.
In above-knee socket applications, HTV Silicone serves as a functional interface material, combining soft tissue accommodation with outstanding mechanical resilience. It enables precise anatomical reproduction while maintaining consistent performance under high dynamic loads.
Key Benefits of HTV Silicone in Above-Knee Sockets
-
Exceptional tear and tensile strength
→ reliable performance in high-stress and high-mobility environments -
Long-term elastic stability
→ maintains cushioning and support without compression set or fatigue -
Excellent biocompatibility
→ skin-safe, non-reactive, ideal for sensitive or compromised tissue -
Superior pressure distribution
→ reduces peak loads and enhances overall socket comfort -
Resistance to moisture, sweat and temperature variations
→ consistent performance in everyday and high-activity use -
High-precision anatomical conformity
→ improved suspension and intimate limb-socket coupling
Prepreg Composite Technology
What is Prepreg?
Prepreg refers to fiber-reinforced composite materials that are pre-impregnated with a precisely controlled resin system. The material is supplied in a partially cured (B-stage) condition and fully consolidated under defined temperature and pressure.
For prosthetic socket manufacturing, Prepreg technology enables maximum structural performance with minimal weight, while offering unmatched consistency and design control. It is the material of choice in aerospace, motorsports—and increasingly in advanced prosthetic engineering.
Key Benefits of Prepreg in Above-Knee Sockets
-
High strength-to-weight ratio
→ lightweight sockets without compromising structural integrity -
Consistent, repeatable material quality
→ predictable performance and reduced manufacturing variability -
Optimized load path engineering
→ stiffness and flexibility tailored to biomechanical demands -
Excellent fatigue resistance
→ long service life under cyclic gait loads -
Slim wall constructions
→ reduced bulk and improved cosmetic outcomes -
Clean, controlled manufacturing process
→ fewer defects compared to wet-lamination methods
