Description:
lnsolflex is a flexible and light weight elastomeric nitrite rubber material designed for
thermal insulation. Insolflex insulation is
black in colour, available in tubing and
sheet form. The extruded flexible tubings
are specially designed to fit the standard
diameters of steel and copper pipings.
Sheets are available in standard precut
sizes or in rolls.
Uses,'
Insoflex expanded closed cell structure
provides the ideal and most efficient
vapour barrier for the prevention of condensation or frost formation on cooling systems, chilled water and refrigerant lines.
Insoflex also retards heat loss for
o
hot
water plumbing and heating, dual temperature piping and solar systems. lt protects
pipes by acting as a vibration damper and
giving protection against corrosion
by
atmospheric and industrial environment.
Insoflex inherent flexibility makes it ideally
suited for the insulation of large surface
area such as tanks, irregular shaped vessels, air-ducts and large diameter pipes.

The above average physical properties are values obtained in accordance with accepted test methods.
At-35", insoflex Closed Cell lnsulation becomes hard and as iemperature drops below
- 40' will be increasingly brittle; however this hardening characteristic does not affect
thermal or water vapour permeability.
The Fire Rating standard method of tests conducted under controlled laboratory conditions is a measure of a material to spread flame when compared to a known standard
and is not intended to reflect hazards presented by this or any other material under actual fire conditions.
