Product Description

Dova MP 303

Melamine Polyphosphate
(Nitrogen and Phosphorus flame retardant)

Product Description

Dova MP 303 is a halogen-free flame retardant based on Nitrogen and Phosphorus, with excellent process properties, high thermal stability, low water solubility, low immigration.

Benefits

1. Dova MP 303 is a halogen-free flame retardant with high purity.

2. Dova MP 303 is white fine powder.

3. Dova MP 303 is with very high thermal stability.

4.  Can be UL94V-0 rating for nylon 6 by adding other flame retardants (i.e. pentaerythritol & ammonium polyphosphate). 

5. DovaFR MPP 307 is a halogen free FR and offers significant advantages in terms of fire safety. It will release lower smoke   density, lower smoke toxicity and less corrosive gases.

Packing & Delivery

Delivery Form

white fine powder

Packaging

Dova MP 303 is supplied in 25 kg bags / 1.000 kg shrink-wrapped pallets.

Storage
Dova MP 303 is non-hygroscopic. However, when stored in open container, the product can still absorb small amounts of moisture owing to the high surface area of the powder. It is in sealed containers at room temperature in a dry place. Partially emptied containers should be carefully resealed after use.
Minimum shelf life is 24months from the date of shipping when stored according to the said conditions.
