Product Description
Product Details
Introduction
Diphenylmethane-type bismaleimide resin (BMI) has excellent heat resistance, electrical insulation, radiation resistance, flame retardancy, good mechanical properties and dimensional stability, molding process similar to epoxy resin and other characteristics.
Quality Indicators
Appearance | Yellow crystalline powder |
Melting point | ≥155℃ |
Acid value | ≤1.0mg KOH/g |
Solubility (15g/75ml toluene reflux) | Fully soluble |
| Purity(HPLC) | ≥98% |
Application
It is widely used in aviation, aerospace, machinery, electronics and other industrial fields as resin matrix, high temperature resistant insulating material and adhesive for advanced composite materials.
Bismaleimide is often used as the raw material of anaerobic adhesives. The adhesive cures quickly in metal threads due to lack of oxygen, forming an aging-resistant and corrosion-resistant sealing structure to ensure the sealing and loosening prevention of threaded fasteners.
