Base film of Maxell LTO2 is based on polyethylene naphthalate that increases its shelf life and helps to stabilize high density recording with low operational costs.
DuPont MCM's range of functional low-temperature curing inks for printed electronics applications employ various advanced resin chemistries enabling a variety of adhesion, flex and thermal properties and compatibility with a broad range of substrates, including paper, polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polycarbonate (PC), FR4 and transparent conductive oxides.
But she conceded that "the biggest proportion of the high material costs" comes from the cost of polymer substrates, like polyethylene terephthalate (PET), polyester, polycarbonate and polyethylene naphthalate (PEN), which require a lot of pre-treatment.
An on-line measurement of birefringence was developed by Cakmak and co-workers and was used to monitor uniaxial stretching of polyethylene naphthalate (11, 12).
