Polyurethane Industry Research Report (Part A)

1. Overview of the Polyurethane Industry

Polyurethane (PU) is an important polymer material, whose wide range of applications and diverse product forms make it an indispensable part of modern industry. The unique structure of polyurethane gives it excellent physical and chemical properties, making it widely used in areas such as construction, automotive, furniture, and footwear. The development of the polyurethane industry is influenced by various factors such as market demand, technological innovation, and environmental regulations, demonstrating strong adaptability and development potential.

2. Overview of Polyurethane Products

(1) Polyurethane Foam (PU Foam)
Polyurethane foam is one of the main products of the polyurethane industry, which can be classified into rigid foam and flexible foam according to different application needs. Rigid foam is commonly used in areas such as building insulation and cold chain transportation boxes, while flexible foam is widely used in products such as mattresses, sofas, and automotive seats. Polyurethane foam exhibits excellent properties such as lightweight, thermal insulation, sound absorption, and compression resistance, playing an important role in modern life.

  • Rigid PU Foam: Rigid polyurethane foam is a foam material with a closed-cell structure, characterized by excellent structural stability and mechanical strength. It is commonly used in applications that require high strength and hardness, such as building insulation, cold chain transportation boxes, and refrigerated warehouses. With its high density, rigid PU foam provides good insulation performance and pressure resistance, making it an ideal material for building insulation and cold chain packaging.
  • Flexible PU Foam: Flexible polyurethane foam is a foam material with an open-cell structure, known for its softness and elasticity. It is commonly used in the manufacturing of mattresses, sofas, and automotive seats, providing comfort and support. Flexible PU foam can be designed into products with different densities and hardness to meet the comfort and support requirements of different products. Its excellent softness and resilience make it an ideal filling material for furniture and automotive interiors.
  • Self-skinning PU Foam: Self-skinning polyurethane foam is a foam material that forms a self-sealing layer on the surface during foaming. It has a smooth surface and high surface hardness, commonly used in products that require surface smoothness and wear resistance. Self-skinning PU foam is widely used in furniture, automotive seats, fitness equipment, and other fields, providing products with a beautiful appearance and durability.
