APP Modified Bitumen Roll Sheet Description

APP Modified Bitumen Roll Sheet is a plastic bitumen blend, which is modified using plastic in the form of atactic polypropylene (APP). As installers begin to torch-apply APP, this type of plastic begins to melt at a point of 300F, where it melts into a liquid wax like substance which acts as an almost free-flowing liquid which can then be mopped across a surface. APP has a high temperature tolerance when heating, so is more user-friendly for installers.
This ease of melting makes APP bitumen popular on smaller roofs such as residential properties and commercial flat roofs.
