What is this TPU I
am hearing about? Why not stick with PUL?
TPU first off is Thermoplastic Polyurethane. The
biggest thing about TPU is that overall it is still PUL. What makes it TPU is
mainly focused just on how and what they laminate the fabric with. PUL
traditionally was bonded with the laminate using a chemical process, where TPU
is heat bonded.
It
is said that PUL which is chemically treated bonds much better than TPU. PUL is
less susceptible to high heat and may last longer because of its stronger
bonding process. TPU may require more precautions with care. High heat can
cause it to delaminate more so than PUL. What makes TPU great is that by using
heat bonding instead it eliminates a large majority of the chemicals needed to
produce the water proof barrier. We suspect that one day when that sacred
diaper reaches the end of its life it will biodegrade faster than its
traditional PUL counterpart. Can you
imagine throwing out one of your cloth diapers?! Lock me up in a room with
nails on a chalkboard, so much better than tossing away a cloth diaper!
TPU can be disputed as superior in look and
feel. It’s stretchier, more flexible, less crunchy and plastic feeling, best of
all softer!
In my personal opinion my TPU diapers have outlasted the traditional PUL
diapers I have had in the past. My TPU still look great on the inside and
outside and show no signs of wear, but my PUL shows more wear while remaining
functional. My few cents anyway!
