Standards-based tools for blending engineers and formulation chemists. Pick a tool, compute inline — no reloads, no registration.
Calculate the exact volume and weight of additive needed for any batch size, plus its TBN contribution.
Volume (L) = Batch Volume (L) × Treat Rate (%) ÷ 100
Weight (kg) = Volume (L) × Additive Density (g/cm³) For wt% treat rate (mass-based):
Weight = Batch Volume × ρ_blend × TR% ÷ 100 (ρ_blend ≈ 0.87)
Volume = Weight ÷ ρ_additive TBN Contribution = TBN_additive (mgKOH/g) × TR_wt% ÷ 100Treat rate is specified as weight percent (wt%) or volume percent (vol%); they differ by density. wt% is the TDS convention.
Our technical team can help with treat-rate optimisation, TBN targets, and additive selection — and send a free sample with TDS & COA.
