SMC & BMC Composites: ATH Selection Guide for Thermoset Molding Applications
PF-COP Ground ATH Grades for SMC, BMC, Electrical Enclosures, and Composite Components
Qingdao Pengfeng provides the PF-COP Series of ground Aluminum Hydroxide (ATH) fillers for Sheet Molding Compound (SMC) and Bulk Molding Compound (BMC) applications. These grades are commonly used in thermoset composite systems including:
- Electrical enclosures
- Automotive composite parts
- Sanitary ware
- Industrial molded components
- Flame-retardant polyester formulations
The PF-COP portfolio offers different particle size distributions to support various processing and formulation requirements in SMC and BMC production.

Selection Considerations
When selecting ATH for SMC and BMC formulations, engineers typically evaluate:
- Particle size distribution
- Oil absorption value
- Filler loading level
- Surface appearance requirements
- Processing characteristics
- Flame-retardant system design
The optimal grade depends on the specific resin system, fiberglass content, processing conditions, and final product requirements.
