PolyRef™ Microplastic Standards

PolyRef™ Microplastic Standards are true-spherical submicron polymer particles (200 nm – 1 μm) manufactured from commercial polymer feedstock via proprietary emulsion-solvent-evaporation routes. Each batch retains the authentic chemical structure of the source polymer, with batch-specific FTIR, SEM, and DLS verification.

The most complete submicron coverage available — LDPE, PVC, PP, and PET — for the four most-cited microplastic categories in environmental research.

Common applications: FTIR/Raman spectral identification reference, sedimentation and density-based separation, UV photo-oxidative aging models, marine microplastic transport studies, ecotoxicology, and environmental fate research.
