Expanded Polypropylene EPP, suppliers

Your advice / assistance please;

I will be manufacturing a small, colorful novelty item this spring.
Objective: needed lightweight FOAM/EPP with the following qualities;

My current sample of EPP is sound.
It is black, 2 inches thick
Also known as clean room foam.

The (the EPP) resistance (bounce back/give properties), smooth look, lightweight features are just what I am looking for. HOWEVER…

1)Do I a have the optimal foam for this project?
2)As mentioned, I need a foam/EPP type product which is/has:
A firm resistance
Clean, smooth finish; able to print or emboss upon
Available in many, many colors
Ability to be die cut

3)In search of Raw material supplier (thickness between 1.5 & 1.75 inches,
As this will be a small novelty, sheet size can vary (at least 2ft by 2ft for Press purposes)

With that said, I am struggling with the location of suppliers in San Francisco/San Jose bay area.
Your feedback & supplier comments would be a great benefit.

Best regards –
