Aidtherm 95A is a mixture of polyether polyol, water, stabilizers, accelerators, etc., mixed with polymer MDI in a high-pressure spraying machine at a ratio of 1.5:1, and then sprayed uniformly on the surface of the steel pipe to form a rigid polyurethane foam. Since the blowing agent in the system is water, it reacts with excess isocyanate to produce carbon dioxide, and at the same time produces a temperature-resistant foam in which polyurethane and polyisocyanurate coexist, which is an environmentally friendly system that is harmless to the environment. The system is developed for the thermal insulation of large-diameter and long-distance pipeline networks in urban central heating where the temperature does not exceed 140 degrees.

● The system contains all the additives and can be used directly

● The foam system has good fluidity and uniform density distribution

● The generated foam has low thermal conductivity, high compressive strength, good dimensional stability, and low water absorption

● When the outer tube and steel pipe are preheated to 30-40℃, the foam has a strong bonding force with the outer tube and steel pipe

● Heat resistance performance (estimated value) below 140 ℃ continuous operation for 30 years

● Environmentally friendly system that does not damage the ozone layer
