Core parameters and influencing factors of polyurethane cell improvement agent

Before a deeper understanding of the practical application of polyurethane cell improvement agents, we need to clarify some key parameters, which directly affect the quality and performance of the foam. The main parameters include density, porosity, compressive strength and rebound. Each parameter has its own unique significance and effect.

Density

Density refers to the mass per unit volume. For foam materials, density directly determines its weight and firmness. High-density foams are usually stronger, but also increase the weight of the material and may not be suitable for certain lightweight applications. In contrast, low-density foam, while lightweight, may lack sufficient strength and support. For example, in automotive seating applications, a suitable density can ensure that the seat is both light and has good support performance.

parameters	Description	Ideal range (kg/m³)
Density	Mass within a unit volume	30-80

Porosity

Porosity refers to the proportion of pores in the foam, and this parameter affects the breathability and sound absorption effect of the foam. High porosity foams usually have good breathability and are suitable for sound insulation materials for ceilings or undercarpets.. However, excessive porosity may cause the foam to be too loose, affecting its structural stability. Therefore, when selecting a cell improver, the relationship between porosity and structural strength must be balanced according to the specific purpose.

parameters	Description	Ideal range (%)
Porosity	The proportion of holes in the foam	70-90

Compressive Strength

Compressive strength measures the resistance of foam when it is under pressure, which is particularly important for components that require long-term load-bearing, such as seats and armrests. High compressive strength means that the foam is not prone to deform when subjected to external forces and can maintain its shape and function. However, if the compressive strength is too high, it may affect the comfort and flexibility of the foam.

parameters	Description	Ideal Range (MPa)
Compressive Strength	The ability to withstand stress	0.1-0.4

Resilience

Resilience refers to the ability of the foam to return to its original state after external force is removed, which is an important indicator for evaluating the comfort of the foam. For car seats, good resilience can reduce discomfort caused by long-term rides. By optimizing the molecular structure of the foam, cell improvers can significantly improve their resilience, ensuring that they provide an excellent comfort experience every time they are used.

parameters	Description	Ideal range (%)
Resilience	Resilience after removal of external force	60-90

By adjusting the above parameters, manufacturers can customize the characteristics of foam materials according to different application needs. Whether it is pursuing lightweight ceiling materials or seat foam that emphasizes comfort, suitable cell improvement agents can play a decisive role. The scientific regulation of these parameters not only improves the functionality of the product, but also greatly enriches the user experience.
