Is DPF 4500 a monomeric or polymeric calendered film?
Short Answer: Polymeric
DPF 4500 is actually considered a blend of both monomeric and polymeric vinyl chloride molecules. It is a majority polymeric. The industry does not use the term blend so it is identified as polymeric due to containing a majority of polymeric moleules.
DPF 4500 can also be referred to as an intermediate polymeric. A premium polymeric calendered film contains all polymeric molecules such as DPF 8000 or 8200.
