PLASTICIZER PLANNING
Vinyl Vibe Plasticizer Calculator
Estimate how much plasticizer you need before you order, based on toy weight, desired softening, and plasticizer type.
1. TOY WEIGHT
You can weigh the toy on a bathroom scale or small kitchen scale.
Rough reference
Many medium inflatables sit around 0.8 to 1.5 kg. Larger multi-chamber toys can be 2 kg or more.
2. DESIRED PLASTICIZER INCREASE
5%
3 to 5 percent is common for toys that are a bit dry. 8 to 10 percent is for very stiff or aged vinyl.
Guidance
This tool is for planning bottle sizes. Always apply in light, even coats and let each coat absorb before adding more.
3. PLASTICIZER TYPE
Density is assumed around 0.986 g/mL. Standard restorative choice.
Rule of thumb
Most plasticizers are slightly lighter than water. For planning, 10 g is roughly 10 to 11 mL across these options.
4. APPLICATION METHOD
Method
Why this matters
Internal application is more “closed system.” Surface work is practical and effective, but it is a little messier and less efficient.
5. ESTIMATED AMOUNT NEEDED
Total plasticizer (grams)
50.0 g
Based on toy weight and chosen percent increase.
Total plasticizer (milliliters)
51 mL
Using approximate density for the selected plasticizer.
Suggested bottle size
4 oz
A 4 oz bottle should be enough with comfortable room to spare.
COMFORTABLE MARGIN
These numbers are planning estimates. Actual absorption and feel will depend on the toy, its age, and how you apply the plasticizer. It is always safer to work in thin coats and let the vinyl fully absorb between treatments.
For reference: 4 oz ≈ 120 mL, 8 oz ≈ 240 mL, 16 oz ≈ 480 mL.
