Frequently Asked Questions
?What are the main applications of Kingflex rubber foam insulation?
Kingflex rubber foam insulation materials are widely used for the heat-insulating and heat-preservation of shells of large tanks and piping in construction, business, and industry, as well as the thermal insulation of joint pipes for both household and automotive air conditioners.
?What wall thicknesses and lengths are available?
The nominal wall thicknesses range from 1/4”, 3/8″, 1/2″, 3/4″, 1″, 1-1/4”, 1-1/2″ to 2” (or 6, 9, 13, 19, 25, 32, 40, and 50mm). The standard lengths provided are either 6ft (1.83m) or 6.2ft (2m).
?What is the thermal conductivity of Kingflex insulation?
According to ASTM C 518 standards, Kingflex insulation has a low thermal conductivity: ≤0.030 W/(m.k) at -20°C, ≤0.032 W/(m.k) at 0°C, and ≤0.036 W/(m.k) at 40°C.
?Does the material provide adequate fire safety?
Yes, it features a Class 0 & Class 1 fire rating under BS 476 Part 6 & 7. Additionally, it has a Flame Spread and Smoke Developed Index of 25/50 (ASTM E 84) and an Oxygen Index of ≥36 (GB/T 2406, ISO4589).
?Is this insulation resistant to environmental factors?
Yes. It displays strong resistance to moisture with a water vapor permeability of ≤0.91×10 ﹣¹³ Kg/(m.s.pa). It also shows excellent resistance to ozone, UV rays, harsh weather, and fungi growth (tested under ASTM 21).
?Is the insulation material safe for environmental and indoor health?
Yes, Kingflex rubber foam insulation supports environmental and indoor health as it is manufactured without formaldehyde.
