Polyester Polyol is a type of polyol that is derived from the reaction between a polyol (such as glycerol or ethylene glycol) and a dicarboxylic acid (such as adipic acid or phthalic anhydride). It is commonly used as a raw material in the production of polyurethane foams, coatings, adhesives, and elastomers.
Polyester polyols have several advantages over other types of polyols. They have good chemical resistance, mechanical properties, and thermal stability. They also have low toxicity and are environmentally friendly. Additionally, polyester polyols can be easily modified to achieve desired properties, such as increased flexibility or flame retardancy.
Polyester polyols are typically liquid at room temperature and have a high molecular weight. They can be further reacted with isocyanates to form polyurethane materials, which have a wide range of applications in various industries, including automotive, construction, and furniture.
Polyurethane packaging foam is a type of foam material that is commonly used for packaging and cushioning products during shipping and transportation. It is made from polyurethane, a polymer that is created through a chemical reaction between polyols and diisocyanates.
Polyurethane packaging foam is known for its excellent shock absorption and cushioning properties. It is lightweight and can be easily molded into various shapes and sizes to fit the specific needs of the product being packaged. The foam is also resistant to moisture, chemicals, and oil, making it suitable for protecting products in various environments.
There are two main types of polyurethane packaging foam: flexible foam and rigid foam. Flexible foam is soft and pliable, providing cushioning and protection for fragile items. Rigid foam, on the other hand, is more dense and firm, providing structural support and protection for heavier items.
Polyurethane packaging foam can be custom-made to meet specific requirements, such as density, firmness, and compression strength. It is widely used in industries such as electronics, automotive, furniture, and medical equipment, where protection and safety during transportation are crucial.
Overall, polyurethane packaging foam is a versatile and effective material for protecting products during shipping and transportation, ensuring that they arrive at their destination in good condition.

Rail cart, also called transfer trolley, transfer cart and climbing transfer cart, is a kind of electric material handling
equipment. This kind of coil transfer cart is powered by cable reel (also called cable drum) to drive wheels and make
the car start, stop, go forward and backward, speed up and slow down and so on. This coil transfer cart can be used
both on the "s" and arc-shaped railways.
