Polyurethane Insulation Pipe Manufacturer Knowledge: What Does Polyurethane Insulation Pipe Material Have?
The insulation material of polyurethane insulating steel pipe is indirectly related to the effect of insulation layer. The formulation used in the foaming process of polyurethane insulating steel pipes is mainly composed of the following raw materials.
1. Polyether, polyester or other polyols - the main reacting raw materials.
2. Polyisocyanates (such as TDI, MDI, PAPI, etc.) - the main reacting raw materials.
3. Water-chain growth agent is also the source of carbon dioxide bubbles.
4. crosslinking agent -- the mechanical function of progressive foam, such as elasticity.
5. catalyst (amine and inorganic tin) - catalyzed foaming and gel reaction rate.

6. the foam wave agent - to make the foam fluctuate and control the size and structure of the hole.
7. external blowing agent - vaporized as the source of bubbles and removes the heat of reaction to prevent bubble center from scorching at low temperatures.
8. Flame retardant - make foam plastics flame retardant.
8. Pigments - provide a variety of colours.
10. Demoulding agent.
