Introduction
Welcome to this comprehensive guide that delves into the technical details of EVA foam density. Whether you’re a manufacturer, engineer, or simply someone curious about materials, this article is designed to provide you with a deep understanding of EVA foam’s density, properties, and applications. We’ll explore everything from how density is measured to its real-world uses, so let’s dive in!
What is EVA Foam Density?
Density refers to how much one cubic meter of foam weighs; it is expressed in kilograms per cubic meter (kg/m³). EVA foam density can range from as low as 33 kg/m³ to as high as 280 kg/m³. The density of EVA foam affects its properties such as flexibility, resilience, and hardness.
How is EVA Foam Density Measured?
EVA foam density is measured by weighing a sample of foam and dividing it by its volume. The volume is calculated by measuring the dimensions of the sample and multiplying them together. The result is expressed in kg/m³.
Physical Properties
When it comes to physical properties, EVA foam is quite versatile. Its hardness levels can vary from 15 to 80 degrees on the Shore C scale. Additionally, its density can range from as low as 33 kg/m³ to as high as 280 kg/m³. This wide range of properties allows EVA foam to be extremely adaptable, making it suitable for a plethora of applications, from lightweight packaging to heavy-duty industrial components.
Manufacturing Process
The manufacturing process of EVA foam is a multi-step procedure that begins with the mixing of raw materials in a Banbury Mixer. This is followed by extrusion, where the material is processed into sheets or rolls. Finally, the foaming process is carried out using an EVA Mold Foaming Vulcanizing Machine, which gives the material its characteristic closed-cell structure. These processes can be customized to produce EVA foam with specific properties, making it ideal for specialized applications.
Applications
EVA foam’s density plays a crucial role in determining its suitability for various applications. Low-density EVA foam is ideal for lightweight packaging, while high-density EVA foam is suitable for heavy-duty industrial components. EVA foam is used in a wide range of applications, including footwear, sports equipment, automotive interiors, toys, and more.
