Optimal perforation pattern maximizes rigidity while minimizing the bolus effect
Variable Perf™ Aquaplast RT™ & Fibreplast™
Variable Perf™ is available in both Aquaplast RT™ and Fibreplast™ low temperature thermoplastic
The optimized perforation pattern containing low and high percentage open areas maximizes the mask’s
rigidity while minimizing the bolus effect that can result in skin reactions.
These masks feature innovative perforated struts. They are more rigid and lower attenuating than traditional
masks that are reinforced with solid strips.
Variable Perf masks are easier to mold, have better working times and form a snug, but comfortable, patient
