EPS or EPP - which Filler is better for Beanbags?

Here's a table comparing Expanded Polypropylene (EPP) and Expanded Polystyrene (EPS) as fillers for bean bags.  Remember, the choice between EPP and EPS depends on the specific requirements of your bean bag application, such as desired firmness, cost considerations, and environmental priorities.

Feature Expanded Polypropylene (EPP) Expanded Polystyrene (EPS)
Material Composition Polypropylene beads expanded with steam and molded Polystyrene beads expanded with blowing agents
Density Higher density compared to EPS Lower density compared to EPP
Durability Highly durable, retains shape and resilience Lighter, can compress over time with use
Weight Heavier due to higher density Lighter due to lower density
Comfort Offers firm and supportive feel Softer and more giving, conforms to body shape
Insulation Properties Good insulator, maintains temperature longer Good insulator, but less effective than EPP
Cost Generally more expensive More cost-effective option
Environmental Impact Recyclable, considered more environmentally friendly Recyclable, but may have a higher environmental impact compared to EPP
Common Applications Premium furniture, automotive parts

Packaging material, bean bags, disposable coolers
