MED-TEC’s ComfortPerf™ thermoplastic material features a special perforation pattern around the eyes and mouth for added patient comfort while maintaining the rigidity and stability of our standard thermoplastic.

ComfortPerf material is available in our disposable Uni-frames and as snap-in sheets for our patented reloadable frames.*

* Reloadable frames accept the carbon fiber McLaurin Arch™ with bite block or custom-form nasal interfaces for enhanced rotational stability.
Thermoplastic Shrinkage Test
We compared the shrinkage of MED-TEC’s ComfortPerf™ Uni-frame® mask against Nuclear Associates’ uon™ mask.

Objective:
To test and compare the shrinkage of MED-TEC’s ComfortPerf™ Uni-frame® mask against Nuclear Associates’ UON™ mask.

Equipment:
• Wooden dummy head
• MT-20100 acrylic baseplate mounted to a test platform
• Digital weight scale
• Water bath and digital thermometer
• (2) ComfortPerf thermoplastic masks
• (2) UON thermoplastic masks

Test Setup:
  1. Attach the dummy head to the scale.
  2. Heat water to the mask manufacturer’s recommended temperature and submerse the mask for a period of five minutes.
  3. Pull the mask over the dummy head.
  4. Allow the mask to air-cool on the dummy head for 10 minutes and record the force reading.
  5. Remove the mask from the dummy head and repeat steps 2 through 4 for the next mask.
  6. Place the mask back on the dummy head and record the scale readings at various time intervals.
Results:

Notes: The plotted values are the average of the masks in each group. Shrinkage (lbs) is calculated by subtracting the 10-minute force reading from the force reading at the time interval. All thermoplastics tested were of equal thickness (2.4mm).

Conclusion:
Test results show that the MED-TEC ComfortPerf exhibits less shrinkage than UON at each post-setup interval.
