Detailed introduction of "Polyurethane PU composite polyether foam material insulation pipe AB composite material wholesale"

< br>

The main raw material of polyurethane insulation material It is a combination of polyurethane rigid foam and polymerized MDI. Polyurethane rigid foam combination polymerization MDI is also called black material, and the combination of polyether is called black and white material. It is suitable for various occasions that require thermal insulation, cold storage, solar energy, water heaters, cold storage, constant temperature storage, beer cans, refrigeration, etc.
Characteristics of Rigid Polyurethane Foam:
1. Excellent thermal insulation performance, high power saving efficiency and environmental protection;
2. Light weight, lower load; excellent waterproof performance, heat preservation and waterproofing 1;
3. Simple design, high efficiency, fast progress, good quality and long service life;
4. Fluorine-free foaming, wide adaptability to the environment; It is not possible to design a closed mold method when casting type), and the necessary closed mold extrusion effect cannot be produced during the molding process. Therefore, the foam formed in the semi-free foaming state often has inevitable molding shrinkage, such as large shrinkage or Non-uniformity will lead to a decrease in the thermal insulation effect and an unsightly appearance. How to strictly control the shrinkage is a crucial part of the tank ingredients and material selection.
Chemical composition and properties
The polyether composition used for thermal insulation is usually composed of polyether, foam stabilizer, catalyst, foaming agent, flame retardant and other components, which can be divided according to different foaming agents There are several main types, such as high fluorine type, fluorine-free 141b type, and fluorine-free full water type.
Generally, the polyether composite material is light yellow or brown-red viscous transparent liquid, without coagulation, thin thick material and unevenness, and no mechanical impurities.

Precautions for safe use
① Adjust the material temperature in an appropriate range during foaming to ensure that the system has suitable reaction performance and fluidity;
② When foaming, the white material should be determined in strict accordance with the requirements of the instructions The ratio of black material to ensure that the process performance of the system and various basic properties of the foam are not affected;
③ Do not let the material come into contact with moisture, and pay attention to proper ventilation at the production site.
