Expanded Polystyrene (EPS) foam molds are generally not waterproof. EPS foam is porous and can absorb water over time, especially if exposed to moisture or submerged in water. However, EPS can be treated or coated to improve its water resistance to some extent. For applications where waterproofing is critical, such as in construction or packaging for items sensitive to moisture, additional waterproofing measures or alternative materials might be necessary.

airplanes made from foam materials like Expanded Polystyrene (EPS) or Expanded Polypropylene (EPP), these are often used in model aircraft or lightweight, experimental aircraft designs. Foam materials offer advantages such as light weight, ease of shaping, and sometimes, impact resistance, making them suitable for certain types of aircraft construction.
