Wide Range of Production
The most suitable size for duct isolation; wıth sheet width 100cm and 120cm,and production in 7 different thickness intervals.
Helps to absorb vibrations that occur in the channel through its elastic structure.
Reduces the use of duct tape at round and square section channels and reduce scrap rates.
Reduces th scrap rate 2-3%.
Operating temperature is between -40 / + 120 °C.
Has as a density of 45-60 kg / m³
Since thermal conductivity coefficient of the elastomeric material is low it reduces the heat transfer significantly (λ ≤ 0.034 W / m•K).
