Target R₀ (solubility-sphere radius, optional):
— if set, results report RED = Ra/R₀ (≤1 = inside the sphere / compatible) and the sphere is drawn on the chart.
Load a polymer:
(handbook solubility spheres; overwrites the target)
force one blend component?
avoid a compound? (anti-target)

AvoidP:
AvoidH:

Anti-target R₀: — the anti-compound's own solubility-sphere radius; the radius rule uses it as the exclusion zone.
Load a polymer:
Rules combine — a solvent is excluded if any checked rule matches. Rules apply to individual blend components (not the blended point); a forced component is never excluded.
filter by boiling point?
keep solvents with bp between and
°C — leave a box blank for no bound on that side
Boiling points are experimental values at/near 1 atm (curated shortlists + PubChem); nothing is estimated, so some compounds have no data. A compound solid at RT is treated as non-volatile: it passes a lower-bp (min) cutoff and is only dropped if you set an upper-bp (max) bound. Custom compounds can carry a bp as an optional 6th CSV field.
plasticizer mode? (rank single compounds near the target; no blends)
keep compounds within distance of the target
— blank uses the target R₀ (the loaded polymer's sphere) if one is set, else no limit; type a value here to override. Run ranks individual compounds by distance to the target instead of searching blends — combine with the avoid section (exclude candidates near an anti-polymer) and the BP filter (e.g. keep only high-bp candidates) to screen for selective plasticizers. Ignores Force. Best-hit-list length still applies. The kept zone shows as a translucent sphere in the chart.

Add custom compounds to search
Paste or type one compound per line: name, CAS, d, p, h — use an empty field for CAS if unknown: My Solvent, , 17.8, 3.1, 5.7
d, p, h are the dispersion, polarity, and hydrogen-bonding Hansen parameters (MPa½). All 5 fields are required.
Optionally append a 6th field with the boiling point in °C (used by the BP filter): Chloroform, 67-66-3, 17.8, 3.1, 5.7, 61.1
