Introduction to Polyurethane Products

Polyurethane products are a series of products produced on the market using polyurethane as the basic raw material, mainly used in large heavy industry manufacturers such as mines, coal washing plants, power plants, steel mills, etc. The polyurethane products produced mainly include polyurethane sieve plates, plates, polyurethane cyclones, etc. Compared with other rubber and nylon products, they have more characteristics such as wear resistance, hydrolysis resistance, and high temperature resistance. Product composition and characteristics High strength rigid polyurethane foam cold insulation pipe holder is mainly made of multifunctional organic isocyanate and mixed polyether polyol? A kind of rigid polyurethane foam prepared by complex chemical reaction under the condition of catalyst and a variety of special additives, which interact with each other. During the production process of the product, due to the selection of specific polyurethane raw materials with greater functionality, and the scientific selection of auxiliary materials and material ratio, the compressive strength of the product has been effectively improved, and the physical and chemical properties of the prepared cold insulation pipe support products can fully meet the requirements of the application process, After testing by relevant authoritative departments, all indicators meet or exceed the technical level of similar foreign products. The products have the following advantages: high density, and can be adjusted according to different application scenarios, with a density of 200-500 kilograms/cubic meter? High compressive strength, up to 4-20MPa? Thermal conductivity 0.052. Has low thermal conductivity, low moisture permeability, and low water absorption, meeting the requirements for cold insulation? It has excellent hydrolysis resistance, aging resistance, acid and alkali resistance and other chemical properties? Not easy to burn, flame retardant meets the density requirements of national safety requirements- The density of the 165 degree to 180 degree pipe holder ranges from 300 to 500 degrees. The thickness of the insulation layer is 100mm
