Silane Modified Ammonium Polyphosphate (APP)

Silane Modified Ammonium Polyphosphate (APP) by Lemman Laboratories International is a flame retardant based on phosphorus / nitrogen synergism and is free from formaldehyde. It is different from APP in the following properties i.e. reduce solubility & viscosity in water, improves dispersibility and thermal expansion efficiency during inflaming retarding process & insulation performance as well as shows compatibility with polymers & resins. It is used in epoxy and unsaturated polyester resin, especially for all kinds of outdoor waterproof, sunlight-flame retardant polymers. Silane Modified Ammonium Polyphosphate (APP) is also used in cables and rubber, silicone resin as well as in electrical and electronic materials.
