BMI-3000 CG Low Cost Bismaleimide (Imide Extended) in Powder Form

Harmonization Code : 2925.19.95.90 | Carboxyimide-function compounds (including saccharin and its salts) and imine-function compounds : Imides and their derivatives; salts thereof : Other : Other : Other

Main features

Superior thermal stability
High adhesion to various substrates
Hydrophobic toughener

Product Description

BMI-3000 Commercial Grade is a low cost bismaleimide oligomer that exhibits excellent flexibility and, on cure, forms very tough, hydrophobic polyimides. The material has excellent low pH hydrolytic resistance and thermal stability. As an additive it can improve rheological properties by increasing the thixotropic properties of a liquid monomer composition. This feature in turn can help to reduce resin bleed out on a variety of surfaces. It is soluble in most aromatic and aliphatic solvents such as toluene, xylene, NMP, etc. It can be processed in a resin system as a solid or dissolved in a solvent.

BMI-3000 Commercial Grade is recommended for use as an additive to increase flexibility, hydrophobicity and thixotropy. It has excellent adhesion to a variety of substrates. When used as a base resin, it can produce films that are tough, flexible and demonstrate good peel strength.

Frequently Asked Questions about High Glass Transition Temperature Epoxy Molding Compounds

What is the difference between the Gel and Powder versions of BMI-3000?

Not a whole lot in terms of final product performance. The basic product and properties are the same, and both have the same molecular weight (3,000 daltons). The difference is in the processing. Both of them have a similar reaction process, but at the end, the handling (including the solvent removal) is different, resulting in a different physical form (Gel vs. Powder). Gel is easier to handle, but the Powder is easier to mix into the formulations.

Which product is less expensive the BMI-3000 Gel or the BMI-3000 CG Powder?

Although the reaction cost is the same and the BOM cost is similar, the Gel will ultimately be less expensive to buy in higher quantities. This is because of the handling of material after the reaction is complete. Though the "Commercial Grade" CG Powder is less expensive to produce, the handling afterward makes it a more expensive end product.

What is considered "high volume" production?

Many of the current products are made in 40-gallon reactors and we have the capability to run up to 200-gallon reactors which will yield around 100kg. We do have the capability to increase these batch sizes if needed to meet higher production batches and can be turned on on an "as-needed" basis.

Is the low-volume material produced the same as the high volume material?

Yes. We have many, many years of experience in scaling up formulated liquids. Although the production equipment gets bigger, the process is the same and scalable.
