Polyol Polyester Containing Cellulose Nanofibers – for the Production of Hard Foam
Application:
This product is used as cold insulation in oil, gas and petrochemical industry.
Product Introduction:
In this product, new types of polyols are synthesized based on natural materials and then they are formulated in order to prepare rigid insulating polyurethane foams with special physical and mechanical properties. This product uses types of polyols based on natural materials as a complete replacement for polyether polyols in the production of insulating polyurethane foams. In this process, a special synthetic system and nano cellulose (as a reactive raw material) have been used. In this way, with the participation of nano cellulose in the polymerization process, it is possible to prepare natural base polyols with appropriate hydroxyl number and viscosity to prepare hard polyurethane foam with appropriate properties.
Technical Specifications:
One of the ways to improve the mechanical-thermal properties of the resulting foams is to introduce very low percentages of nano cellulose and modified lignin fibers into natural base polyols. These materials have suitable functional groups as well as proper distribution and distribution in the polyurethane substrate, and for this reason, they have received attention.
This product has three special functional aspects:
1. Due to the synthesis of special nanopolyol and its polymerization
2. In terms of the synthesis of nano polyol with different specifications (in three different grades with different branches and functional groups)
3. From the aspect of formulation with different additives, catalysts to produce foam with isocyanate. It should be noted that this product is synthesized in several processes (at least two steps) and formulated in several steps. One of the advantages of this method is that this process is not sensitive to water or humidity. Nano cellulose is also used as a suspension in water.
Advantages:
High strength of the product at a reasonable price
International Standards or Permission:
The special function of the product is the preparation of rigid insulating polyurethane foams with properties according to the (strict) ASTMC591 standard.
