What is cast polyurethane like?
Castable polyurethane is a series of products produced on the market with polyurethane as the basic raw material. It is mainly used in large-scale heavy industrial production enterprises such as mines, coal washing plants, power plants, and steel plants. Casting polyurethane mainly includes polyurethane screens and plates, polyurethane cyclone separators, etc. Compared with other rubber and nylon products, it has the characteristics of abrasion resistance, hydrolysis resistance and high temperature resistance.
Composition and characteristics of cast polyurethane The high-strength rigid polyurethane foam insulation pipe bracket is mainly made of multifunctional organic isocyanate and mixed polyether polyol. In the presence of catalysts and various special additives, they interact and complex chemical reactions occur. Reaction to prepare rigid polyurethane foam? In the production process of the product, due to the selection of specific polyurethane raw materials with greater functionality, and the scientific selection of screening materials and material ratios, the compressive strength and physical and chemical properties of the product are effectively improved. The cold tube support products produced can fully meet the requirements of the application process.
After testing by relevant departments, all indicators have reached or exceeded the technical level of similar foreign products. Casting polyurethane has the following advantages: high density, can be adjusted between 200-500kg/m3 according to different applications. The compressive strength is high, up to 4 ~ 20MPa. The thermal conductivity is 0.052. The thermal conductivity is low, the moisture permeability is low, and the water absorption rate is low, which meets the requirements of cold storage. Does it have excellent water resistance, solution stability, anti-aging, acid and alkali resistance and other chemical properties? It is not easy to burn, and its flame retardancy meets the national safety requirements for density; -165 degrees -180 degrees, and the pipe clamp density is between 300 and 500. Insulation thickness 100 mm
The general advantages and characteristics of cast polyurethane:
1. Good abrasion resistance: castable polyurethane has excellent abrasion resistance
2. Wide range of hardness: The hardness of cast polyurethane is about Shore A10-D80, while the hardness of ordinary rubber is generally Shore A60-100. It is worth noting that within such a hardness range, the polyurethane elastomer can have an elongation of 400-800%. The maximum hardness of natural rubber at 550 elongation is Shore A70.
3. Castable polyurethane has high strength and high elongation.
4. Excellent oil resistance: castable polyurethane has better oil resistance than cyanide rubber; aging resistance is better than natural rubber and other synthetic rubbers; polyether polyurethane is better than polyester in hydrolysis resistance and acid and alkali solution corrosion resistance Polyurethane.
5. Pouring polyurethane has excellent characteristics such as light weight, high strength, heat insulation, sound insulation, flame retardancy, cold resistance, corrosion resistance, non-water absorption, simple and quick construction, etc. It has become an indispensable thermal insulation material in construction, transportation, petroleum, chemical, electric power, refrigeration and other industrial sectors. Waterproof, leak plugging and sealing, etc. For a long time, Suzhou Jiahua Polyurethane Products Co., Ltd. has been committed to the innovation and research of polyurethane technology, and has successfully developed a variety of special castable polyurethanes for users.
