What is urethane foam? We will explain its characteristics and uses.

basic information

―――Characteristics of Urethane Foam――― Urethane foam has the following characteristics: * Lightweight and easy to handle * Cushioned * Easily absorbs shock * Flexible and can be processed into various shapes * Available in a wide variety of thicknesses and hardnesses Utilizing these characteristics, it is used in various applications such as product protection, vibration damping, and sound absorption. ―――Main Types of Urethane Foam――― Ether-based Urethane Foam This type is resistant to hydrolysis and has excellent durability. It is used in a wide range of applications, including packaging materials, cushioning inside cases, and cushioning materials within equipment. Ester-based Urethane Foam This type has excellent mechanical strength and abrasion resistance. However, it is more prone to hydrolysis in high-temperature and high-humidity environments, so material selection must be tailored to the usage environment.
