PUR and EVA require different adhesive handling and operating discipline. PUR can support demanding moisture and heat applications, but the finished edge depends on adhesive selection, machine equipment, substrate, tape, joint design and process control.

How to compare supplier answers
Put every quotation into one comparison sheet. Use the same panel, tape, adhesive, process stations, utilities, acceptance test, spare-parts scope, delivery basis and support requirements. A lower price with missing stations or services is not the same offer.
Ask who is responsible for each unresolved item and when it will be closed. Electrical configuration, compliance documents, packing, lead time, installation, warranty and payment terms should be fixed before the order is accepted.
