Phenolic resin used as a pyrotecnic binder

Phenolic resin used as a pyrotecnic binder

Phenolic resin used as a pyrotecnic binder

(OP)
Commonly used in China as a adhesive binder in fireworks compositions. Almost unheard of in USA.

Yellow amber looking brittle small lumps that will reduce to powder & is partialy soluable in alcohol.

Is a binder of choice cited below.

International Peer-reviewed Journal on energetic materials.

International Pyrotechnics Society.

Volume 9, Issue 3, pages 127 - 132 June 1994

The Influence of the Various Types of Binder on the burning characteristics of the magnesium-, boron-, and aluminum-based igniters

Abstract
The behavior of six different types of binders phenol-formaldehyde resin, shellac, polyvinylchloride, ethylcellulose, nitrocellulose, and fluorel was investigated in pyrotechnic compositions on the basis of magnesium, boron and aluminum. It has been found that the nature of the binder significantly influences the burning characteristics of the igniters. Correlation has been found between binder exothermicity and investigated characteristics. In addition, the influence of the contents of phenol-formaldehyde resin and of fluorel, in the range of 0% to 25% on the same performance characteristics was studied. >>Phenol-formaldehyde resin has been chosen as preferred binder for the investigated igniters in an amount of 5%.<<

Also binder of choice here.

Any idea of the formulation and/or small supply source in USA.
Looking to test it a flamable binder in a flare composition.

Thanks for any hints, direction or help.

Did you try google. Phenol formaldehyde is a VERY common commodity used to make plywood, brake pads and clutch facings ash trays and many other things.

RE: Phenolic resin used as a pyrotecnic binder

(OP)
I have googled for days looking.
I am looking for raw resin.
Everyone that has resin, seems to have added a LOT of fillers.
All of which defeat the use I am looking at.
I found a source in China.
Minimum order is 2 metric tons FOB.
I just need a few lbs for testing purposes.

RE: Phenolic resin used as a pyrotecnic binder

My information is 15 years old, but it lists Monsanto and Union Carbide. Others listed are Ametek, Reichhold, Schenectady Chem. and Ashland Chemical. I think Ashland are still current

The address I have is

Emabond Systems
Specialty Polymers and Adhesives Division
Ashland hemical
49 Walnut Street
Norwood NJ
USA
201 767 7400

Also, Amcore still sell some, at least in Australia.

Filled grades are listed as from Occidental, Plaslok, Plastics Engineering and Valite.
