Moisture in EPS beans as a filler in Poufs, Bean Bags, and other Cushioned Furniture.

 

Moisture in EPS (Expanded Polystyrene) beans can significantly impact their performance as a filler in poufs, bean bags, and other cushioned furniture. Here’s what you need to consider:

Effects of Moisture in EPS Beans:

1. Loss of Buoyancy & Comfort – EPS beads are lightweight and designed to provide cushioning. Moisture can cause them to stick together, reducing their ability to move freely and distribute weight evenly.

2. Mold & Mildew Growth – If the moisture content is high, especially in humid environments, it can lead to mold or mildew, affecting hygiene and durability. It can also create fungus in the poufs.

3. Compression & Shrinkage – Wet beads may clump together and lose volume over time, reducing the pouf’s lifespan and requiring frequent refills.

4. Increased Weight – Moisture absorption makes the pouf heavier, affecting portability and ease of use.

5. Pricing of Poufs - If the moisture in the EPS in high it will increase the cost of EPS due to low weight of EPS and high weight of moisture.

 

Recommended Moisture Levels:

Ideally, EPS beads should have a moisture content below 1% to maintain their properties.

Proper drying and storage before filling the poufs is essential.

Preventing Moisture Issues in Poufs:

1. Use a Waterproof or Moisture-Resistant Liner – Helps prevent absorption of external humidity.

2. Ensure Proper Storage – Keep EPS beads in a dry, sealed container before use.

3. Dry EPS Beads if Needed – If beads are suspected to have absorbed moisture, they can be dried using low heat or in a well-ventilated area.

4. Choose High-Quality EPS Beads – Virgin or high-quality recycled beads are less likely to absorb moisture than lower-quality alternatives.
