Polyurethane soft foam production presents challenges such as uneven pores, rough textures, and chaotic pore sizes. These issues often stem from design flaws in batch foam machines. Manufacturers sometimes overlook the practical implications of their designs on foam quality. In this article, we address these common problems and provide valuable insights from real-world experiences. Tips on adjusting mixing wheel position, blade shape, length, and speed optimization are discussed. By optimizing batch foam machines, foamers can achieve superior polyurethane foam quality.

Is the foaming of polyurethane soft foam sponge stable? It is measured mainly in relation to the hardness, density, elasticity, tensile strength and porosity of the foamed sponge.

Polyurethane foam(PU foam) primarily consist of polyurethane as their main component. The raw materials primarily include polyisocyanates and polyols, with the addition of various additives, the most crucial of which are a series of foaming agents related to the foaming process. These additives lead to the production of a significant amount of foam within the reaction product, resulting in polyurethane foam products.

Polyurethane material is a block polymer containing carbamate characteristic groups produced by the reaction of polyisocyanate and hydrogen donor. Because of the various appearance forms of the generated products, its application has entered various fields of the world economy.

For many small-scale enterprises, although the continuous production line of polyurethane flexible foam offers high output, the costs are also very high, and the target market may not require such large quantities. As a result, non-continuous production lines for polyurethane flexible foam have become their preferable choice.
