Orthovinyl vinyl ester resin
Orthovinyl lamination resin is a vinyl ester-based resin that is easy to process and can be used to fabricate thin-walled, stable laminates.
Orthovinyl lamination resin is a vinyl ester-based resin that is easy to process and can be used to fabricate thin-walled, stable laminates.
Due to its structure, it bonds to carbon fiber more effectively than an acrylic resin. This achieves a high degree of stiffness at a low laminate wall thickness, which falls between that of an acrylic resin and that of an epoxy resin.
Nevertheless, Orthovinyl can be processed as quickly and easily as an acrylic resin. The standard Ottobock 617P37=0.150 hardener can be used.
| Material | Vinyl ester |
| Scope of application | Orthosis lower limb, Orthosis upper limb, Prosthesis lower limb, Prosthesis upper limb |
| Use | Definitive socket production, Definitive orthosis production |
All benefits at a glance
- The resin exhibits a slightly yellow tinge in the liquid state which is not, however, visible in the laminate
- As with an acrylic resin, the setting time can be reliably determined based on the added hardener and the temperature
- Higher degree of stability than an acrylic resin due to better bonding to the reinforcement fibers
- Very easy to sand
- Excellent balance between matrix and reinforcement material
- Can be colored with Ottobock pigment pastes
- Small number of layers possible
- Very good impregnation, especially of carbon fibers
- The product fulfils all performance and safety requirements for the manufacture of medical devices provided that the prescribed instructions for use are observed
Processing instructions
- All standard Ottobock carbon fiber and fibreglass products can be processed with Orthovinyl. Please note the information in the safety data sheet.
- Use Ottobock 617P37=0.150 hardening powder
- Do not use any thinners
- Final annealing: one hour per 1 mm laminate thickness at 80 °C
Safety instructions: For further information on the safety instructions, please see the corresponding Ottobock safety data sheet.
