Polyester resin is not considered food safe. It is often used in applications like boat building and crafting but can leach harmful chemicals and toxins, especially when exposed to heat or food items. For food contact surfaces, materials like food-grade epoxy or silicone are recommended instead. Always check for specific food safety certifications when selecting materials for food-related projects.
What else can I help you with?
Is fiberglass resin an epoxy or polyester?
Fibreglass resin is a polyester.
Is polyester resin a thermo plastic or thermosetting?
Once polyester resin cures (hardens) through a chemical reaction—usually with a catalyst like MEKP—it forms a rigid, cross-linked structure that cannot be melted or reshaped again. This irreversible curing process is the key characteristic of thermosetting materials. In contrast, thermoplastics soften when heated and can be remolded multiple times, which polyester resin cannot do after curing. That’s why polyester resin is widely used in fiberglass, boat hulls, automotive parts, and construction—applications where heat resistance and structural strength are essential.
