Abstract

A boron nitride composition comprising at least two different boron nitride powder materials having different properties, e.g., surface areas, particle size, tap density, etc.

Claims (16)

1. A boron nitride composition comprising at least two different types of boron nitride powder materials, wherein the boron nitride powder materials are platelet boron nitride powder material and spherical agglomerates of boron nitride powder material, the spherical agglomerates being untreated.

2. The boron nitride composition of claim 1 , further comprising a boron nitride powder material selected from the group consisting of platelet boron nitride powder material, agglomerates of boron nitride powder material, partially crystalline boron nitride powder material, amorphous boron nitride powder material, turbostratic boron nitride powder material and nano boron nitride powder materials.

3. The boron nitride composition of claim 1 , wherein the spherical agglomerates of boron nitride comprises agglomerates having different sizes.

4. The boron nitride composition of claim 1 , wherein the boron nitride materials have particle size distributions distinct from each other.

5. The boron nitride composition of claim 1 , wherein at least one of the boron nitride powder materials has an average particle size of at least 5 microns.

6. The boron nitride composition of claim 1 , wherein the platelets have an average diameter of at least about 1 micron.

7. The boron nitride composition of claim 1 , wherein the agglomerates have an average particle size of 5 to 500 microns.

8. A polymer composition comprising a boron nitride filler containing at least two different types of boron nitride powder materials wherein the boron nitride powder materials are platelet boron nitride powder material and spherical agglomerates of boron nitride powder material, the spherical agglomerates being untreated.

9. The polymer composition of claim 8 , wherein the polymer is at least one selected from the group consisting of polyester, melt-processable polymer, phenolic polymer, silicone polymer, acrylic polymer, wax, thermoplastic polymer, low molecular weight fluid, liquid crystal polymer and epoxy polymer.

10. The polymer composition of claim 8 , wherein the polymer is at least one selected from the group consisting of polyethylene naphthalate, polyethylene terephthalate, polybutylene terephthalate, polyphthalamide, polyimide, polyamide, polyphenylene sulfide, polycarbonate, polyetheretherketone, polyaryletherketone and polyphenylene oxide.

11. The polymer composition of claim 8 , further comprising different types of boron nitride powder materials selected from the groups consisting of agglomerates of boron nitride powder material, partially crystalline boron nitride powder material, amorphous boron nitride powder material, turbostratic boron nitride powder material and nano boron nitride powder materials.

12. The polymer composition of claim 8 , wherein the boron nitride materials have particle size distributions distinct from each other.

13. The polymer composition of claim 8 , wherein at least one of the boron nitride powder materials has an average particle size of at least 5 microns.

14. The polymer composition of claim 8 , wherein the platelets have an average diameter of at least about 1 micron.

15. The polymer composition of claim 8 , wherein the agglomerates have an average particle size of 5 to 500 microns.

16. The polymer composition of claim 8 , wherein the spherical agglomerates of boron nitride comprise agglomerates having different sizes.
