Plasticised PVC (Plastisol)

PVC was known for decades as a hard, brittle powder nobody could use. In 1926 Waldo Semon at B.F. Goodrich found that certain liquids dissolve it only when hot, and that the hot solution sets on cooling into a soft, rubber-like gel - flexible PVC. **US 1,929,453**, "Synthetic rubber-like composition and method of making same", Semon, assigned to B.F. Goodrich, granted 10. October 1933, claims dissolving "an insoluble polymerized vinyl halide at an elevated temperature" in a liquid that dissolves it only well above room temperature, and gelling it by cooling. One example: 8 parts PVC, 8 parts tricresyl phosphate, 3 parts dibutyl phthalate. **Plastisol is that idea in a bottle**: PVC grains suspended, undissolved, in plasticiser. Heat makes the liquid dissolve the grains and fuse into solid flexible PVC. You bake test films at three temperatures and pull them apart to find where it truly fuses.

Mga Tagubilin

1

Ventilate and set the oven

Use a toaster oven kept for crafts, never food, by an open window. Put the probe thermometer inside - dial settings are rarely accurate.

Stir the plastisol

The PVC grains settle. Stir the plastisol from the bottom for 2 minutes until even. Read the label's fusion temperature.

History & Context

**What the patent specifies:** gelling PVC in high-boiling liquids such as tricresyl phosphate and dibutyl phthalate. **Modern build (derived):** a commercial plastisol; many now use phthalate-free plasticisers. Flexible PVC became cable insulation, shower curtains, hoses and flooring. Its limits: the plasticiser slowly migrates out, so old soft PVC stiffens and turns sticky; and overheated PVC yellows and releases hydrogen chloride, which is why the label's maximum temperature matters.
