How to use the delayed low-odor amine catalyst LED-204 to significantly reduce the odor problem of polyurethane products

3月 12th, 2025 News

Using the delayed low-odor amine catalyst LED-204 significantly reduces the odor problem of polyurethane products

Introduction

Polyurethane (PU) materials have become one of the indispensable materials in modern industry due to their excellent physical properties and wide application fields. However, polyurethane products are often accompanied by obvious odor problems during production and use, which not only affects the user experience, but may also cause potential harm to the environment and human health. To solve this problem, the delayed low-odor amine catalyst LED-204 came into being. This article will introduce in detail the characteristics, mechanism of action, application scenarios of LED-204 and how to significantly reduce the odor of polyurethane products through it.

1. Source of odor problems of polyurethane products

1.1 Basic composition of polyurethane materials

Polyurethane materials are mainly composed of polyols, isocyanates and catalysts. During the reaction, isocyanate polymerizes with polyols to form polyurethane polymer chains. However, some by-products will be produced during this process, such as unreacted isocyanates, amine compounds, etc., which are the main sources of odor.

1.2 Main ingredients of odor

The odor of polyurethane products mainly comes from the following types of substances:

  • Unreacted isocyanate: Isocyanate has a strong irritating odor that can be perceived even in trace cases.
  • Amine compounds: Amine compounds are commonly used catalysts in polyurethane reactions, but they themselves have a strong ammonia odor.
  • Volatile Organic Compounds (VOCs): During the production of polyurethane, some low molecular weight organic compounds may be produced, which are volatile and prone to odor.

1.3 The impact of odor on the environment and health

The smell of polyurethane products not only affects the user experience, but may also cause potential harm to the environment and human health. Long-term exposure to high concentrations of isocyanate and amine compounds may lead to respiratory irritation, skin allergies and other problems. In addition, the release of VOCs may also cause pollution to the atmospheric environment.
