Which one has higher adhesive strength and peel strength after curing, polyether polyurethane or polyester polyurethane

The adhesive strength and peel strength of polyether polyurethane after curing are generally higher than those of polyester polyurethane. This is because polyether polyurethane has better elasticity and wear resistance, as well as higher tensile and bending strength. Therefore, in some cases, polyether polyurethane is more suitable for applications that require high adhesion and high peel strength than polyester polyurethane.
