Otoplastic 3Dresyn OTO-HF, Biocompatible Hard & Flexible otoplastic 3D resin with Shore D70

Otoplastics 3Dresyn OTO-HF has these features and benefits:

• ideal for the production of durable clear and colored hard and flexible ear molds and other otoplastics, hearing aids and medical devices
• 100% foldable without breaking
• excellent transparency / clarity
• non yellowing with excellent light fastness
  
• clear, water white, colorless
• excellent impact shattering resistance (Notched Izod <85 J/m)
• isotropic to minimise difraction / scattering
• hydrophobic, ultra low water absorption ULWA
• tough and semirigid (Young modulus <500 MPa)
• high tensile strength, <20MPa
• high flexural strength <20 MPa
• Shore hardness D70
• elongation <40%
• durable
• very high resolution (printing resolution of less than 20 microns)
• very low shrinkage
• printable by most commercial and professional SLA, DLP & LCD 3D printers

Note: 3Dresyn OTO-HF contains monomers, which cause eye and skin irritation (and may cause allergy). 3D printed otoplastics need to ensure that 3D resins are fully reacted and any potential extractables, leachables, residuals, and byproducts are fully eliminated by implementing the right printing, postcuring and cleaning protocols to ensure maximum biocompatibility.
