Plan a trial for your application
Cable compounds
In the target resin at the specified thickness, test flame performance, elongation and extruded surface.
Highly filled composites
At fixed loading, compare melt torque, dispersion and mechanical properties.
Purchase specifications and incoming inspection
Review these properties for the intended application grade. Example figures refer to the cited grade or source. Confirm the offered specification, packaging and lead time in the quotation. Huber MAGNIFIN · Flame-retardant magnesium hydroxide fillers ↗
| Property | Unit | Published or agreed specification | Test conditions and checks |
|---|---|---|---|
| Particle size distribution | µm | Confirm against the offered grade and purchase specification | Specify D50, the coarse fraction and measurement conditions. |
| Magnesium hydroxide assay | % by mass | Confirm against the offered grade and purchase specification | Distinguish the base material content from the surface treatment. |
| Surface treatment | Type or % by mass | Confirm against the offered grade and purchase specification | Request a declaration of the treatment agent and verify compatibility with the resin. |
When approving a sample, record the grade, methods, limits and specification revision. On receipt, match the packing lot number to the lot-specific COA and record the measured values and release decision.
From samples to commercial delivery
Packaging and receiving
Check liner, compaction, net weight and sampling positions for powder packs.
Storage and handling
Keep dry, record moisture exposure and retain mixed material and finished test pieces.
Sample and order lead times
State the finished part, machine trial quantity and routine order size. Match trial and commercial grades and agree MOQ, load unit, lead-time start and arrival.
Questions from the plant
Does the flame-retardant filler guarantee a finished-part rating?
Test the complete formulation at the actual wall thickness under the applicable end-use standard.
Why do grades with the same nominal size produce different extrusion torque?
Check the full size distribution, surface treatment and moisture condition, then compare processing curves.
Report a delivery or batch issue
Include the order number, lot number from the package, label photos and inspection records for the affected lot. When retesting, check Particle size distribution, Magnesium hydroxide assay, Surface treatment.
