How to use polyurethane sponge pore agent to improve the production process of soft foam products: from raw material selection to finished product inspection

How to use polyurethane sponge pore agent to improve the production process of soft foam products: from raw material selection to finished product inspection

Introduction

As a polymer material widely used in the fields of home, automobile, packaging, etc., the performance of polyurethane sponge directly affects the quality of the final product. In the production process of soft foam products, the selection and use of pore agents have a crucial impact on the pore rate, breathability, elasticity and other properties of the product. This article will discuss in detail how to use polyurethane sponge pore agent to improve the production process of soft foam products, from raw material selection to finished product inspection, and strive to provide relevant practitioners with a set of systematic and scientific guidance solutions.

1. Function and selection of polyurethane sponge pore opening agent

1.1 The function of pore opener

The pore opener mainly plays a role in regulating the foam structure in the production process of polyurethane sponges. By controlling the porosity of the foam, the porosant agent can significantly improve the breathability, elasticity and compression properties of the foam. Specifically, the functions of pore-opening agents include:

Adjust the foam structure: The pore opener can promote the bursting of bubbles inside the foam, forming an interconnected pore structure, thereby increasing the pore openness of the foam.

Improved breathability: Foams with high porosity have better breathability and are suitable for application scenarios where good ventilation performance is required.

Enhanced Elasticity: The pore agent can optimize the elastic modulus of the foam so that it can quickly return to its original state after being compressed.

Improving compression performance: By adjusting the pore rate, the pore agent can improve the compressive permanent deformation performance of the foam and extend its service life.

1.2 Selection of pore agent

Selecting the right pore opener is the key to optimizing the production process of soft foam products. Here are a few factors to consider when selecting a pore opener:

Types of pore openers: Common pore openers include silicones, surfactants and polymers. Different types of pore agents have different impacts on foam performance and need to be selected according to specific needs.

Domic of pore opening agent: The dosage of pore opening agent directly affects the pore opening rate of the foam. Too little dosage may lead to insufficient porosity, and too much dosage may lead to too loose foam structure.

Compatibility with raw materials: The pore-opening agent needs to have good compatibility with polyurethane raw materials to ensure that it can be evenly dispersed during the production process and avoid local uneven pores.

Environmental protection: With the increase in environmental protection requirements, choosing environmentally friendly pore openers has become an industry trend. Environmentally friendly pore openers can not only meet production needs, but also reduce environmental pollution.

1.3 Parameters of pore opening agent

The following are the main parameters of some common pore opening agents:

Pore-opening agent type Main Ingredients Applicable temperature range (℃) Recommended dosage (%) Environmental

Silicones Dimethylsiloxane 20-80 0.5-2.0 High
