Abstract

An intumescent polymer composition includes a matrix polymer, an acid catalyst source, a nitrogen source and an ionic phyllosilicate synergist having substantial cationic exchange capacity. Particularly preferred ionic phyllosilicates are montmorillonoids whereas pentaerythritol phosphate is a preferred acid catalyst source:

Claims (11)

1. A flame retardant additive composition for dispersing in a matrix polymer composition to promote intumescence comprising:

(a) an acid catalyst source;

(b) a nitrogen source;

(c) an ionic phyllosilicate having a cationic exchange capacity of at least about 5 meq per 100 g thereof; and

(d) optionally including an organic polyol as a carbonific char-promoting agent,

wherein said layered ionic phyllosilicate is present in an amount of from about 0.5 to about 10 percent by weight of said additive composition.

2. The flame retardant additive composition according to claim 1 , wherein said layered ionic phyllosilicate is a montmorillonoid ionic phyllosilicate.

3. The flame retardant additive composition according to claim 2 , wherein said acid catalyst source comprises a component selected from the group consisting of bicyclic organophosphorous compounds and ammonium polyphosphate.

4. The flame retardant additive composition according to claim 1 , wherein said nitrogen source is a melamine compound.

5. The flame retardant additive composition according to claim 1 , wherein said acid catalyst source comprises pentaerythritol phosphate alcohol.

6. The intumescent composition according to claim 1 , wherein said composition further comprises a metal oxide or metal salt.
