1.Smooth appearance 2.Good flexibility 3.Small tolerance 4.Great thermal conductivity
Jesion NBR tube is a black, flexible elastomeric foam tube used to conserve energy and prevent condensation on piping applications. The tube closed cell properties create exceptional thermal and acoustic insulation, protect against moisture penetration and provide the best solution for applications within a -280°F to +221°F temperature range. It is primarily used in the HVAC/R market and comes in 6 feet or 2 meet length. It is 25/50-rated, according to ASTM E-84 standards for surface burning characteristics of building materials.
Heating:Excellent heat insulation performance, greatly reduce heat loss, convenient economy installation.
Ventilation:Also meet the world’s most rigorous fire safety standards, greatly improved the safety performance of the materials, applicable to all kinds of ventilation ductwork.Cooling:High soft degree, easy installation, applicable to the condensate pipes systems, cold media quality system in the fields of the insulation.Air conditioning:Prevent condensation produce effectively, help air conditioning system to improve efficiency and create a more comfortable environment.
