With a PTFE inner liner convoluted hose can
protect against chemical
and fuel attack.
DeWAL Industries DW 350 materials are specialty
aluminum foil materials coated with PTFE coatings. These
materials are used primarily as process aid materials in the
manufacture of convoluted hose. DW 350 can also be used as
release liners in other converting processes.
Our coated aluminum is manufactured using a direct deposit roll
coating process. This process controls the thickness uniformly
across the entire web. DW 350 is supplied in slit widths from ½”
to 12” wide.
