Hot Compressing Melamine Moulding Compound Excellent Electrical Properties
Hot-compression melamine moulding compound with outstanding electrical properties, high arc resistance and dielectric strength. Thermosetting powder for low-voltage electrical insulating parts, heat-resistant, self-extinguishing. Support OEM & ODM bulk factory wholesale.
Product Overview
Our Hot Compressing Melamine Moulding Compound with Excellent Electrical Properties is electrical-grade thermosetting melamine-formaldehyde moulding powder specially optimized for hot compression molding. Formulated with modified melamine-formaldehyde resin and high-performance reinforcing fillers, this material delivers superior dielectric strength, arc resistance and tracking resistance.
After hot pressing curing, finished parts maintain stable insulation performance under humid and high-temperature working conditions. Apart from great electrical features, it also owns good heat resistance, mechanical strength and self-extinguishing property. Widely used for manufacturing low-voltage electrical insulating components, instrument parts and special industrial molded products. Stable batch-to-batch quality, suitable for large-volume hot-compression production.
Core Advantages & Main Product Structure
Core Advantages
- Outstanding Comprehensive Electrical Properties: High dielectric strength, great insulation resistance, excellent arc-resistance and proof-tracking index. Effectively prevent electric leakage and arc carbonization under operating conditions.
- Stable Performance Under Humid & High-Temperature Environment: Insulation performance will not drop sharply after moisture absorption; maintains reliable electrical safety for long-term service.
- Good Mechanical & Thermal Performance: High flexural and impact strength, high heat-distortion temperature, self-extinguishing UL94-V0 flame retardant grade, anti-deformation under continuous heat load.
- Reliable Hot-Compression Molding Processability: Stable fluidity for hot compression molding, good mold filling capacity, low shrinkage rate, reduces bubble and crack defects for complex-shape electrical parts.
- Chemical & Corrosion Resistance: Resist weak acid, weak alkali and daily chemical erosion; finished insulating parts keep stable dimension in complex industrial environments.
Main Product Structure
This electrical-grade melamine moulding compound adopts cross-linked melamine-formaldehyde resin as matrix, compounded with special cellulose reinforcing fillers and electrical-performance optimized functional additives. Uniform fine-powder structure ensures even heat transfer and full cross-linking curing during hot compression.
The compact cured molecular structure realizes high-level insulation, arc-resistance and mechanical toughness simultaneously, meeting strict requirements of electrical insulating components.

Production, Quality Inspection & Packaging
Production Process
Adopt fully-closed automated production workflow: raw material polymerization, formula compounding with electrical-grade additives, high-precision grinding and powder screening. Strict raw-material screening controls impurity content, ensuring consistent electrical-performance indicators for each production batch.
Quality Inspection
Every batch undergoes complete lab testing before shipment, including appearance inspection, fluidity test, mechanical strength test, heat-distortion test and full electrical-performance detection (insulation resistance, dielectric strength, tracking index, arc resistance). Third-party test reports are available upon request. Strict batch difference control avoids performance fluctuation for electrical-product manufacturing.
Packaging & Storage
- Standard Packaging: 25 kg paper-plastic composite bags with inner PE moisture-proof liner; prevent moisture absorption during sea-transport. Custom printed bags are supported.
- Storage Conditions: Store in cool, dry and ventilated warehouse, keep away from high temperature, humidity and direct sunlight. Keep bags sealed; shelf-life 12 months under qualified storage conditions.
