Frequently Asked Questions
What binder systems are compatible with your powder?
Our powder is compatible with all standard epoxy resins (compression) and thermoplastic binders like Nylon-6, Nylon-12, and PPS (injection).
Can you customize the PSD (Particle Size Distribution)?
Yes, we can adjust the sieving process to provide custom PSD profiles to optimize your specific molding equipment.
What is the Minimum Order Quantity (MOQ)?
Standard MOQ is 25kg (one drum) for stocked grades. Custom grades may require larger quantities.
How should the powder be handled and stored?
Store in a cool, dry place. Once the vacuum seal is broken, use within 24 hours or reseal with inert gas (Nitrogen/Argon).
Is MSDS available for shipping?
Yes, we provide full MSDS and safety documentation for air and sea freight compliance.
