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.
Denso and Japan Fiji Form Alliance to Develop Next Generation Exhaust Emission System
Denso Corporation and Ibiden Co formed a capital alliance and a corporate alliance to jointly develop the next generation of automotive exhaust emission systems.
After the establishment of the alliance, Ibi Electric Co., Ltd. of Japan combined its products' superiority—high-performance ceramic materials and professional expertise in product development, systematically developing a variety of simple and inexpensive cars. Exhaust emission system. Denso will acquire third-party allocation to purchase the stocks (treasury stock) of Ibi Electric Co., Ltd. in Japan. In addition, powertrains are increasingly diversified. In response to market demand, the two companies will consider cooperation in the field of vehicle electrification to make the process more efficient.
This cooperation is due to the same interest requirements of the two companies and the increasingly stringent global vehicle exhaust emission planning, forcing companies to continuously improve the efficiency of internal combustion engines. The alliance has accelerated the development of the exhaust system of high-performance internal combustion engines (including gasoline engines, diesel engines, hybrid engines, and plug-in hybrid generators).
Denso has developed and provided various system components to better control the intake, power and exhaust emissions of gasoline engines and diesel engines during the work cycle. Nippon Ibi Electric Co., Ltd. is committed to its ceramic business and actively develops high-performance ceramic materials, and applies it to diesel particulate filter (DPF) and diesel exhaust emissions system.
