EPS Foam Density

EPS foam density is typically measured in units of pounds per cubic foot (lbs/ft³).

EPS Foam Density Chart

Density Range (lbs/ft³)CharacteristicsApplications
Low (1.0 – 1.5)* Very lightweight and airy * Excellent thermal insulation * Excellent cushioning and shock absorption* Packaging fragile items (electronics, appliances) * Disposable cups and coolers
Medium (1.5 – 2.0)* Relatively lightweight * Slightly more structural rigidity than low density * May offer some crush resistance* Packaging applications requiring some crush resistance
High (2.0+)* Significantly denser and heavier * Superior strength, durability, and impact resistance * Improved moisture resistance

* Construction (roof insulation, under-slab insulation, concrete formwork) * Heavy-duty packaging (bulky, heavy, or fragile items) * Industrial applications (buoyancy tanks, boat hulls, specialized molding)

FAQs about High Density EPS Foam

What is high-density EPS foam?

High-density EPS foam, also known as high-performance EPS, is an enhanced version of the regular EPS foam. And you might see packing electronics or used in disposable cups. It’s made from the same basic material, polystyrene, but with a higher concentration of it packed into the same volume. This creates a denser and sturdier foam with several advantages over its less-dense counterpart.

Superior Strength & Durability: High-density EPS foam packs more material into its structure, resulting in a sturdier and more rigid foam. This translates to:

  • Higher Load Capacity: It can support greater weight without deforming or breaking. This makes it ideal for construction applications like roofs or concrete formwork that need to bear significant weight.
  • Enhanced Impact Resistance: High-density EPS can absorb impacts more effectively, protecting the contents within. This is crucial for packaging delicate or heavy items during transport.
  • Longer Lifespan: Due to its robust nature, high-density EPS foam can withstand wear and tear for extended periods, minimizing replacements and repairs compared to regular EPS.

Enhanced Moisture Resistance: Regular EPS foam can absorb moisture, which can compromise its performance and integrity. High-density EPS has a denser structure that limits moisture absorption. This makes it suitable for applications exposed to water or humidity, such as foundations, basements, or marine environments.

Cost-Effective in the Long Run: While the upfront cost of high-density EPS foam might be slightly higher than regular EPS, consider these factors:

  • Reduced Replacement Needs: The superior strength and durability of high-density EPS minimize the need for frequent replacements, leading to cost savings over time.
  • Improved Performance: Its enhanced properties ensure your project functions optimally for a longer period, reducing maintenance costs associated with repairs or premature failure of regular EPS.

High-density EPS foam itself is not biodegradable. However, it can be recycled in many locations. Some manufacturers even offer take-back programs where they collect used EPS foam and recycle it into new products. This helps minimize its environmental impact by diverting it from landfills. When considering eco-friendliness, look for manufacturers who prioritize sustainable practices and explore the recycling options available in your area.

High-density EPS foam offers good machinability, meaning it can be easily worked with using various tools and techniques. Here’s a breakdown:

  • Cutting: High-density EPS foam can be cut with standard tools like EPS cutting machine, hot wires, or even CNC machines. The specific cutting method depends on the desired shape and the scale of the project.

  • Shaping: Due to its consistency, high-density EPS foam can be shaped using EPS shape molding machine. This allows for customization to fit specific application needs.

  • Molding: High-density EPS foam can be molded into complex shapes using specialized molds and a heating process. This is particularly useful for creating custom components or parts for industrial applications.

Choosing the right material depends on the specific requirements of your project. Here are some factors to consider:

  • Project Requirements:

    • Strength and Durability: Evaluate the weight-bearing capacity and impact resistance needs for your application.
    • Moisture Resistance: Consider if your project will be exposed to water or humidity.
    • Thermal Insulation: For applications requiring insulation properties, compare the thermal conductivity of high-density EPS foam to other options.
  • Cost-Effectiveness: While high-density EPS foam might have a slightly higher initial cost, factor in the long-term benefits like reduced replacements and improved performance compared to other materials.

  • Environmental Impact: Consider the recyclability of high-density EPS foam in your area and compare it to the environmental footprint of alternative materials.
