Electrical Components Applied Melamine Formaldehyde Powder Tripolycyannitrogen-containing compound Anti Heat
Product Overview
Heat-Resistant Melamine Formaldehyde Powder is an industrial-grade tripolycyanamide-based amino thermosetting moulding compound, specially formulated for manufacturing electrical insulation components. Formulated with high-purity melamine-formaldehyde resin, inorganic reinforcing fillers and heat-stable functional additives. After hot compression curing, finished parts deliver outstanding heat resistance, arc resistance, excellent electrical insulation property and stable dimensional performance. This moulding powder is widely adopted for producing high-performance electrical accessories under long-term high-temperature working conditions for electrical factories.
Core Advantages & Main Product Structure

Frequently Asked Questions
Q1: What key performance does this electrical-grade melamine formaldehyde powder have?
A: It features outstanding heat-resistance, arc resistance and high electrical insulation. Finished components can keep stable electrical performance under long-time high-temperature working environment.
Q2: What molding equipment fits this tripolycyanamide-containing compound?
A: It is suitable for melamine hydraulic hot-press machine. Recommended molding pressure:25-40 Mpa, temperature:155-170℃. Matching automatic weighing machine and preheating machine improves production efficiency.
Q3: Can you adjust formula for different electrical component requirements?
A: Yes, OEM formula tuning is available. We can optimize heat-resistant, arc-proof and shrinkage index according to your finished-product drawing and working condition.
Q4: Can this powder be used for food-contact tableware?
A: This is industrial electrical grade, not for food-contact usage. Please select our A5 food-grade melamine moulding compound if you produce tableware.
Q5: How to store this heat-resistant melamine formaldehyde powder?
A: Store in cool, dry and ventilated warehouse, avoid moisture and direct sunlight. Shelf life is 12 months from manufacturing date. Damp environment will cause powder agglomeration.
