Frequently Asked Questions
What is the temperature range for this rubber foam insulation tube?
This insulation tube is engineered to perform reliably within a wide temperature range of -50°C to 110°C, making it suitable for both hot and cold pipeline systems.
What are the primary applications of this product?
It is widely used to insulate chilled water pipes, condense pipes, air ducts, and hot-water pipes in air-conditioning equipment across industrial plants, clean rooms, public areas, and medical institutions.
How does the insulation handle moisture and water vapor?
Thanks to its completely closed-pore foaming structure, the material offers excellent moisture resistance and low water vapor permeability (≤0.91×10 ﹣¹³ Kg/(m.s.pa)), preventing condensation buildup.
Does this insulation material meet fire safety standards?
Yes, it achieves a Class 0 & Class 1 fire rating according to BS 476 Part 6 & Part 7, and has a flame spread and smoke developed index of 25/50 under ASTM E 84 testing.
Is the material durable against environmental factors?
Yes, testing via ASTM methods confirms that the material provides good resistance to fungi, ozone, ultraviolet (U.V.) light, and general weathering, ensuring a long service life.
