In the realm of advanced electronics and high-end manufacturing, the performance of the material defines the potential of the device. BDI-2000 is an addition-type high-performance polyimide resin that sets a new standard. With its exceptional purity, stable molecular weight distribution, and outstanding high-frequency dielectric properties, it serves as the ideal matrix resin for copper-clad laminates, aerospace adhesives, and specialized protective materials. As a high-performance polymer engineered for extreme environments, BDI-2000 perfectly balances processability with the structural integrity of the final product.

Core Product Features
1. Superior High-Frequency Dielectric Performance
At a 1kHz test condition, BDI-2000 maintains a stable dielectric constant of 3.85. Combined with the inherently low dielectric loss of polyimide resin, this material is ideally suited as a base resin for high-frequency and high-speed copper-clad laminates. In the 5G/6G communication era, signal integrity and low latency demand materials with stable and consistent dielectric properties. Through high-purity control (≥99.5%) and a low acid value (≤1.0 mg KOH/g), BDI-2000 minimizes signal interference caused by ionic impurities, making it a core material for high-fidelity transmission in printed circuit boards.
2. Excellent Thermal Stability
As an addition-type polyimide, BDI-2000 forms a highly cross-linked, rigid network upon curing. Its melting point range (160-170°C) provides a wide processing window, while the cured parts can withstand prolonged exposure to demanding high-temperature environments. This high temperature resistance makes it a preferred material in the aerospace industry for structural bonding of materials like titanium alloys and ceramics, ensuring reliability under extreme operating conditions.
3. High Purity and Low Acid Value
The acid value is a critical indicator of residual carboxyl content in the resin. BDI-2000 strictly controls this value to below 1.0 mg KOH/g, offering significant advantages:
Enhanced Hydrolysis Resistance: Minimizes the risk of imide ring opening in hot and humid environments.
Improved Processing Safety: During high-temperature curing, a low acid value results in fewer volatiles and side reactions, facilitating the production of bubble-free, high-performance films or coatings.
4. Outstanding Mechanical and Flame Retardant Properties
Based on its rigid molecular chain structure (rich in benzene and imide rings), cured BDI-2000 exhibits high strength, high modulus, and a low coefficient of thermal expansion. Furthermore, its inherent flame retardant properties meet UL94 V-0 standards without the need for additives. When exposed to flame, it rapidly carbonizes, forming an insulating layer that effectively prevents combustion and eliminates molten drips, making it a reliable choice for safety protection applications such as coatings for flame-retardant protective clothing.
Applications
High-Frequency Copper-Clad Laminates: Used as the primary resin for laminates in AI servers, autonomous driving systems, and smart medical devices requiring high-speed signal processing.
Aerospace Structural Adhesives: Formulated into specialty adhesives for long-term structural bonding of metals and composites at temperatures up to 260°C.
Functional Powder Coatings: Utilizes its self-lubricating and wear-resistant properties for sliding components requiring a low friction coefficient.
Molding Compounds: Produces high-strength abrasives or high-temperature engineering plastic parts.
Processing and Usage Guidelines
Compatibility: BDI-2000 exhibits excellent intermiscibility with reactive monomers such as VM-3540 and AM-317, allowing formulators to adjust cross-linking density to meet specific performance targets.
Solvent Recommendations: It is soluble in high-polarity solvents such as NMP (N-Methyl-2-pyrrolidone) and DMAC. Under heating, it can also be dissolved in benzene or ketone-based solvents to accommodate various coating processes.
