Korolath Plastic Shims - Compressive Strength

(Note: All results are stated as examples only. Not for use in engineering. Specific product data can be supplied upon request.)

Compressive strength varies based on material and thickness. In testing the materials results have been found as follows;

Polypropylene - 5,500 to 8,000 psi

Hi-Impact Polystyrene - 6,000-8,000 psi

Polyethylene - 2,000 to 5,500 psi

ABS (acrylonitrile butadiene styrene) - 6,500 to 7,500 psi

As thickness increases compressive strength decreases. For example, for the same material at 1/16" thick the compressive strength may be 8,000 psi while at 1/4" thick compressive strength may be 4,000 psi
