Safety & Health

Health Hazard

Phthalic Anhydride is not poisonous. However, inhalation, or prolonged exposure must be avoided. Its dust irritates the mucous membrane. It is recommended to wear Safety Goggles,
while handling this material. Always refer to the Material Safety Data Sheet (MSDS) for detailed information on safety.

Fire and Explosion Hazard:

Phthalic Anhydride whether molten or solid is an inflammable material and its dust and vapors can form explosive mixture, when in contact with air. It is essential to store or handle the
material in a well-ventilated area away from any source of ignition.

Packaging & Availability

Packaging Type
Packaging

1. Laminated HDPE / PP Bags. Net Weight - 25 Kg


2. Bulk Bags. Net Weight - 1000 /750 /600 /500 Kg
Full Container Load (FCL):
1.Loose stuffing of 25 Kg Bags:
840 X 25 Kg Bags = 21 MT / FCL
2.Palletised & Stretch Wrapped
Packed in 25 Kg Bags
40 X 25 Kg Bags / Pallet = 1.0 MT
36 X 25 Kg Bags / Pallet = 0.9 MT
32 X 25 Ke Bags / Pallet = 0.8 MT
a) 1.0 MT X 10 Pallets and 0.8 MT X 10 Pallets
= 18 MT / FCL
b) 1.0 MT X 10 Pallets and 0.9 MT X 10 Pallets
= 19 MT / FCL
Full Container Load (FCL):
3. Packed in Bulk Bags:


a) 1000 Kg X 10 and 750 Kg X 10 bulk bags
on Pallets = 17.5 MT / FCL
b) 600 Kg X 3 Bulk Bags on Pallet =
1.8 MT X 10 Pallets = 18 MT / FCL
c) (500 Kg X 2 Bulk Bags on Pallet X 10=10 MT)
+ (25 Kg X 32 Bags on Pallet X 10 = 8 MT)
= 18 MT / FCL
(500 Kg Bulk Bag is Antistatic Bag)

Storage & Handling

Storage

Phthalic Anhydride should be stored in cool, properly covered, dry area, away from direct sunlight. It should not be exposed to rain/ humidity as this leads to formation of Phthalic Acid,
which is insoluble in Benzene and lowers the Melting Point
