HGM Common Series
Eight grades spanning the HGM working range — from the lightest, lowest-strength option to a high-density, high-strength grade — giving formulators a single series for most lightweighting and filling applications.
Grade Comparison
AM-H15 to AM-H60. Density, compressive strength, and thermal conductivity rise with the model number; particle size trends smaller.

Compressive strength test per JC/T 2285-2014 or Q/TIPC-J01-2020. Tap density per GB/T 31057.1-2014. True density per JC/T 2285-2014 or GB/T 21782.2-2008. Thermal conductivity per ASTM D5930-01. Particle size per GB/T 19077-2016.
How to Choose a Grade
As the model number increases, density, compressive strength, and thermal conductivity all increase together, while particle size (D50) trends smaller. Lower-numbered grades (AM-H15, AM-H20) suit applications prioritizing minimum density and cost efficiency where pressure resistance requirements are modest — coatings, low-pressure fillers. Higher-numbered grades (AM-H46 to AM-H60) suit applications with higher pressure or structural demands where a higher-density, higher-strength trade-off is acceptable.
Applications
Plastics, Rubber & Building Materials
General-purpose lightweighting filler improving dimensional stability and reducing shrinkage in resin and composite systems.
Coatings & Adhesive Tapes
Reduces raw material usage while improving insulation and surface finish.
Oilfield & Marine
As a drilling fluid additive and buoyancy material component, lowers slurry/fluid density while maintaining strength.
