In a thermoset polymer, the bonds between different chains are typically covalent bonds.

Covalent bonds are strong bonds that occur when two atoms share one or more pairs of electrons. These bonds are what give thermoset polymers their high stability and resistance to heat. Once these bonds are formed, they cannot be broken and reformed easily, which is why thermoset polymers do not melt when heated. Instead, they tend to char or burn.

Ionic bonds, secondary bonds, and metallic bonds are not typically found in thermoset polymers. Ionic bonds occur between metals and non-metals and involve the transfer of electrons. Secondary bonds are weaker than covalent bonds and include hydrogen bonds and van der Waals forces. Metallic bonds occur between metal atoms and involve a sea of delocalized electrons.
