how to test self adhesive flange discs
self adhesive flange disc is protected for flange raised face ,so it can be allow blasting or coating of interior while protecting flange raised face
it is Easy to install not like tape
in market for self adheisve have paper type ,film(PE,PVC)type ,NBR rubber
paper type can not sealed the blasting or coating,so coating is not safety
film type can not sealed with flange face ,also easy tear
NBR rubber Is good for sealed , good Tensile strength
