TWO: MIX RUBBER
Polytek 75-60 Polyurethane Mold Rubber provided the ideal flexibility for this project. The 75-60 was stiff enough to hold our desired shape without kinking at the curves while a softer mold rubber would have bellied or sagged at the curve points. Work quickly when mixing polyurethane mold rubber in order to avoid having the material setup before pouring.
What You’ll Need
Step 1 – Calculate Rubber Quantity
Step 2 – Mixing Rubber
Step 3 – Add Part A to Part B
Step 4 – Second Mix
Step 5 – Dry Gas Blanket and Cleanup
Previous: Make Mold
This project begins with a 3/4″ thick template made of melamine coated particle board which will be encased in polyurethane mold rubber to create a flexible mold.
Next: Cast Rubber Mold
Polyurethane mold rubber behaves like glue and will stick to most materials, so make sure that all surfaces are protected with Pol-Ease Mold Release.
