Plexiglas® Design Stresses Avoid Stresscrazing

Plexiglas® sheet has good tensile and flexural strength properties. However, stress will produce light surface cracks known as crazing. To avoid stresscrazing, design limits for continuously imposed loads should not exceed 1,500 psi for Plexiglas® G sheet and 750 psi for Plexiglas® MC sheet. Stresses of greater magnitude but short duration will not generally cause stress-crazing.
