Features of polyurethane foam opening agent

Polyurethane foam opening agent is an auxiliary agent used in the process of preparing foamed polyurethane. Its function is to form an open cell structure in the polyurethane foam after polymerization, thereby improving the flexibility, elasticity and sound absorption and noise reduction performance of the foam. . Polyurethane foam opening agents usually use low molecular weight, high activity polyester polyols, which have the following characteristics:

Good opening effect: The polyurethane foam opening agent can effectively control the solidification rate of the foam cell wall during the polymerization reaction, thereby forming an open cell structure and improving the quality of the polyurethane foam.

High compatibility: The polyurethane foam opening agent has good compatibility with the polymer, and will not affect the physical and chemical properties of the polyurethane foam.

Strong adhesion: The polyurethane foam opening agent can be fully mixed with other functional additives (such as softeners, flame retardants, etc.) and substrates (such as wood, metal, etc.), and has strong adhesion in the polyurethane foam and is not easy to lose.

Good stability: Polyurethane foam opening agent has good stability, and will not change due to factors such as long storage time and storage environment, and will not affect production and processing.

Low toxicity: Polyurethane foam opening agents are usually made of non-toxic and harmless materials, which are harmless to humans and the environment, and are a green and environmentally friendly product.
