Frequently Asked Questions
What forms are melamine moulding compounds available in?
Our melamine moulding compounds are suitable for compression molding and are available in both powder and granular forms.
Can I customize the color of the Melamine Moulding Compound?
Yes, Melamine Moulding Compounds are available in an unlimited range of colors. Runtai provides color-matching services according to the Pantone color card or based on real samples provided by customers.
What are the primary applications of melamine powder?
Melamine powder is widely used in manufacturing imitation porcelain tableware and containers, medium/low voltage electrical components, and mahjong tiles due to its excellent physical and chemical properties.
Why is melamine powder preferred for electrical components?
Melamine powder exhibits outstanding electrical properties under high temperature and wet conditions, alongside superior arc resistance and scratch resistance, making it ideal for electrical components.
How should melamine moulding compounds be stored?
It should be stored in a dry, cool, and well-ventilated room with an ambient temperature not exceeding 25°C. Avoid exposure to heat, moisture, contaminants, and packaging damage during transport.
What is the shelf life of melamine moulding compound?
The standard shelf life is six months. If the storage period is exceeded, the compound must be inspected according to product technical standards; it can still be used if it passes inspection.
