With the improvement of environmental awareness, more and more enterprises have begun to pay attention to the environmental protection of packaging materials. In this context, polyurethane packaging foam came into being. Compared with traditional foam packaging materials, polyurethane packaging styrofoam has the following advantages: First, polyurethane packaging styrofoam meets Rohs reach environmental protection requirements and can be exported to Europe, America, Japan and South Korea, which is a relatively environmentally friendly material.
Secondly, polyurethane packaging foam has high cushioning performance, which can effectively reduce the vibration and collision of goods during transportation, thereby reducing the damage rate of goods.
Finally, polyurethane packaging styrofoam has good air permeability and moisture resistance, which can keep the goods dry and fresh. Therefore, polyurethane packaging styrofoam has become the choice of more and more enterprises, which can not only protect the environment, but also improve packaging efficiency and the safety of goods.
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.
