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 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.
PU resin, also known as polyurethane resin, is widely used in the production of synthetic leather. Synthetic leather, also referred to as faux leather or artificial leather, is a man-made fabric that imitates the appearance and feel of genuine leather. PU resin is a key component in the manufacturing process of synthetic leather, as it provides the material with its durability, flexibility, and water resistance.
The process of producing synthetic leather involves coating a fabric substrate, such as polyester or nylon, with a layer of PU resin. This resin is typically applied in liquid form and then undergoes a curing process to solidify and bond with the fabric. The resulting material has a leather-like texture and appearance.
PU resin offers several advantages for synthetic leather production. It has excellent abrasion resistance, making the synthetic leather more durable and long-lasting. It also provides flexibility, allowing the material to be easily shaped and molded into different forms. Additionally, PU resin offers good water resistance, preventing the synthetic leather from absorbing moisture and becoming damaged.
Moreover, PU resin can be customized to achieve different finishes and textures, such as smooth, grainy, or embossed patterns, depending on the desired aesthetic. It can also be colored in various shades to mimic different types of leather. This versatility makes PU resin a popular choice for synthetic leather manufacturers.
Overall, PU resin plays a crucial role in the production of synthetic leather, providing the material with its desirable qualities of durability, flexibility, and water resistance.

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.
