maleic anhydride

Hello, my friend! The product you need is here! Keep reading please. Or you can contact me now, I will tell you all the information you need by myself.

Applications
Maleic anhydride is used in many applications. Around 50% of world maleic anhydride output is used in the manufacture of unsaturated polyster resins (UPR). Chopped glass fibers are added to UPR to produce fiberglass reinforced plastics that are used in a wide range of applications such as pleasure boats, bathroom fixtures, automobiles, tanks and pipes.

A number of smaller applications for maleic anhydride. The food industry uses maleic anhydride in artificial sweeteners and flavor enhancements Personal care products consuming maleic anhydride include hair sprays， adhesives and floor polishes. Maleic anhydride is also a precursor to compounds used for water treatment detergents, insecticides and fungicides，pharmaceuticals and other copolymers.

Something You Must Know!
Liquid maleic anhydride is available in road tankers and/or tank-containers which are made of stainless steel, which are insulated and provided with heating systems to maintain the temperature of 65-75℃。Tank cars must be approved for the transport of molten maleic anhydride.

Liquid/molten maleic anhydride is a dangerous material in accordance with RID/ADR.

Solid maleic anhydride pastilles are transported by transport trucks. Packaging is generally in 25kg polyethylene bags.

Storage
Requirements for storage buildings:
Local exhaust systems to take vapors away from the places of emission, and general ventilation in rooms.
Protection against static charges.
Impervious floor which makes it possible to collect the spilled material and which prevents its entry to the sewage systems.
Storage rooms should be cool and dry.

Storage conditions:
Keep ignition sources away- do not smoke.Product dust may form explosive air-dust mixtures.
Keep humidity away from storage rooms.
Keep containers tightly closed. Store them in cool, dry and well ventilated places.
Tanks/containers must be properly marked.
Hand-operated/ portable fire-fighting equipment should be available in storage rooms.
Neutral gas blanketing is required inside storage tanks.
Attention, please!
Maleic anhydride is a low hazard profile chemical. Maleic anhydride rapidly hydrolyzes to form maleic acid in the presence of water and hence environmental exposures to maleic anhydride itself are unlikely. Maleic acid is biodegradable under aerobic conditions in sewage sludge as well as in soil and water.
