Application of delayed amine catalyst A400 in durable polyurethane tires
Introduction
Polyurethane (PU) materials are widely used in tire manufacturing due to their excellent wear resistance, elasticity and mechanical properties. However, traditional polyurethane tires may experience performance degradation under certain extreme conditions (such as high temperature, high humidity, high load, etc.). To solve these problems, the delayed amine catalyst A400 was born. This article will introduce in detail the application of delayed amine catalyst A400 in durable polyurethane tires, including its working principle, product parameters, application advantages and actual case analysis.
1. Working principle of delayed amine catalyst A400
1.1 The role of catalyst
The catalyst plays a role in accelerating the reaction rate in the polyurethane reaction. Although traditional catalysts can trigger reactions quickly, they can in some cases lead to excessive reactions and affect the performance of the final product. The delayed amine catalyst A400 makes the polyurethane reaction more controllable by delaying the reaction time, thereby improving the uniformity and durability of the product.
1.2 Mechanism of delayed reaction
The delayed amine catalyst A400 can maintain a low activity at the beginning of the reaction through a specific chemical structure, and gradually release the activity as the reaction progresses, thereby achieving precise control of the reaction rate. This mechanism not only improves the uniformity of the reaction, but also reduces bubbles and defects during the reaction, and ultimately improves the durability of polyurethane tires.
