Flexible Denture Base Resin
Elastic denture-base resin described by the TDS
The RF-TJ-09 TDS describes an elastic denture-base resin with resilience comparable to traditional injection molding, together with high precision, strong toughness, and fatigue resistance. Treat the listed settings and material data as starting points for laboratory validation.

TDS Post-Processing & Storage
- 1
Wash — Clean with absolute ethanol or isopropyl alcohol in a low-frequency ultrasonic cleaner. High-frequency or high-power ultrasonic cleaning may damage the printed surface.
- 2
Dry — Blow the printed part completely dry with a hair dryer or similar tool.
- 3
Remove supports — Remove supports before post-curing; removal after curing can damage support-contact areas.
- 4
Conditional post-cure — When additional toughness is required, UV cure for 5 minutes.
Storage
Store in a cool, dry place below 25°C, away from direct sunlight and visible light to prevent polymerization or gelation.
Safety and use status
The current TDS states that the resin is not approved for food, drink, or medical application on the human body. Review the SDS and verify current intended use and regulatory status before any clinical use.
Printers Listed in the TDS
Processing technology: LCD/DLP. The following representative devices are the only printer models named in the current TDS.
Use the table above as a calibration starting point, not as universal compatibility approval.
Transitional Workflow Described in the TDS
The RF-TJ-09 TDS introduction describes an elastic denture base resin and temporary transitional restorations. Its Applications field instead lists “Dental model”, and its Safety section states that the resin is not approved for medical application on the human body. Confirm the current intended use, product documentation and applicable registration with RayForm before any clinical use.
RF-TJ-09 Technical FAQ
- QWhat does the current TDS describe RF-TJ-09 for?
An elastic denture-base material and temporary transitional workflows before implantation or fixed restoration. This description is not a regulatory approval. - QWhat are the key TDS values?
Shore D 71–75, tensile strength 45 MPa, elongation at break 100%, flexural strength 95 MPa, and flexural modulus 1000 MPa. - QWhich printing technologies are listed?
LCD and DLP, with starting profiles for the five representative printer models shown above. - QHow should printed parts be cleaned?
Use absolute ethanol or isopropyl alcohol in a low-frequency ultrasonic cleaner, then blow dry completely and remove supports before post-curing. - QDoes this page claim approved clinical use?
No. Confirm the current intended use, regulatory status, and valid local protocol before any clinical use. - QWhich properties should I compare when selecting this resin?
Compare tensile strength, elongation at break, hardness and flexural modulus together. The RF-TJ-09 TDS lists reference values of 45 MPa, 100%, 71–75 Shore D and 1000 MPa, respectively. Results depend on equipment, environment, settings, post-processing and test methods; confirm the process for your printer and intended application. - QWhere can I buy the resin or ask about B2B bulk procurement?
See the product listing for retail options for RF-TJ-09 Flexible Denture Base Resin. Distributors and laboratories planning bulk material procurement can use Request a B2B quote. Include your required quantity, printer, intended application and target market so RayForm can review your requirements.
