1. Product Profile
Ammonium perchlorate (AP) is white crystal, soluble in water and hygroscopic. It is a kind of strong oxidizers. When AP is mixed with reducing agent, organics, inflammable materials, such as, sulfur, phosphorus or metal powder, the mixture can caused the risk of burning or explosion. When it is contacted with strong acid, the mixture can also have the risk of explosion.

3. Application: Ammonium Perchlorate (AP) has been used as an oxidizer for rocket propellant and mixed explosive. It can also be used in fireworks, hail prevention agent, oxidizer, analytic agent, etching agent, etc. It can also be used to produce other borohydrides, reducer, drifting agent for wood and paper, foaming agent for plastics, boranes, etc. In addition, AP is used in measurement of phosphor content and medicines.
4. Package: Iron barrel packaging with inner plastic bag. After removing the air in the bag, the mouth of the bag should be tightened.
5. Storage: Stored at cool, dry and ventilate place. Forbid to heat and sun-baked. Shelf life: 60 months. It is still available if the retest results of the properties are qualified after expired date. Keep away from inflammable and explosive goods. Do not store together with reducing agent, organic, combustible goods.
6. Transportation: Avoid rain, sun-baked. No violent collision.
