A-P26
A-P26 low-halogen flame-retardant granule for PP extrusion
A-P26 is documented as uniform bright white granule for Homopolymer PP / Copolymer PP. The source TDS lists 4% homopolymer PP; 6% copolymer PP and positions the grade for resin-specific flame-retardant formulation trials.

What this grade is positioned to support
- Flame-retardant formulation evaluation
- Direct-add processing trial
- Thickness-specific verification
How to prepare the first evaluation
- 01
Pre-dry A-P26 for 2 hours at 90°C.
- 02
Blend directly with PP without an added synergist during the first trial.
- 03
Keep molding temperature below 220°C and verify flame class on the final part.
Current TDS and application guidance
Source file: a-p26-tds.pdf. UL94 and oxygen-index statements require current evidence on the final formulation and thickness. Fillers, pigments, resin grade and processing temperature can materially change flame performance.
