polyethylene (LDPE) tubing is lined with fluorinated ethylene propylene (FEP)
to provide a composite tubing.
The strength of
LDPE supports the thin wall liner of chemically inert FEP to provide the same
performance as heavy wall FEP tubing at a fraction of the cost.
The liner does
not contain plasticizer and does not alter the chemical composition of water
samples collected for testing.
temperature range is -25 to +180°F (-32 to 82°C). Jacket hardness Shore D 43.
Jacket resists weak acids and bases, and strong oxidizing acids.
easily and does not absorb liquids.
