Advantages of HDPU Foam Against
Mastic
HDPUF have been used for
pipeline installation since the early 1980’s and have proven
to be advantageous in the following areas:
- Non
hazardous – the chemicals and final product do not emit toxic
fumes when dispensed and provides a safe environment for personnel in
the field joint station.
- Handling
– The chemicals expand approximately 6 times the actual
volume. Therefore, 6 times less materials to handle, store and
transport.
- Easy
Application – Dispensing the chemicals do not require high
temperature and therefore eliminate the hazard of burns to the
personnel.
- Chemicals
ready to be used immediately, does not need high labor to prepare.
