In the PU Sandwich Panel Production Line will be used in the polyurethane foam high-pressure foaming machine, so the sandwich panel used in which kind of polyurethane foam?

The two main types of polyurethane foam are:

1. Flexible Polyurethane Foam: Flexible polyurethane foam is a type of foam that is commonly used in cushioning and comfort applications. It is known for its softness, flexibility, and ability to conform to different shapes. Flexible polyurethane foam is widely used in mattresses, upholstery, car seats, pillows, and other comfort products.

2. Rigid Polyurethane Foam: Rigid polyurethane foam is a type of foam that is used for insulation and structural applications. It has a closed-cell structure, which makes it a good thermal insulator. Rigid polyurethane foam is commonly used in building and construction as insulation material for walls, roofs, and refrigeration applications. It is also used in various industries for manufacturing lightweight structural components.

In the polyurethane sandwich panel production line will be used in the polyurethane foam high-pressure foaming machine, sandwich panels used in the second type of polyurethane foam, called the Rigid Polyurethane Foam.

Both types of polyurethane foam are produced by reacting polyols and isocyanates with other additives and blowing agents. The specific combination of ingredients and processing conditions determines the properties and characteristics of the foam.
