How to Fix Cracks in Polymer Clay Sculpts | eHow

How to Fix Cracks in Polymer Clay Sculpts. The clay hardens if baked in a regular oven at temperatures below 300 degrees F. Cracks in polymer clay sculpts form due to sudden temperature changes or when you use the clay to cover a different type of material such as air-dry clay, which dilates or contracts. Fixing cracks is possible both before and after the baking process.

How to prevent stress cracking - Permabond

Some plastics such as ABS, Acrylic, Polycarbonate, and Polystyrene are more susceptible to stress cracking. These are amorphous plastics, and they bond readily. Other plastics such as polyethylene, polypropylene, and polytetrafluoroethylene (Teflon) are semi-crystalline thermoplastics and …

Polymer degradation - Wikipedia

Polymer degradation is a change in the properties—tensile strength, color, shape, etc.—of a polymer or polymer-based product under the influence of one or more environmental factors such as heat, light or chemicals such as acids, alkalis and some salts. These changes are usually undesirable, such as cracking and chemical disintegration of products or, more rarely, desirable, as in biodegradation, or …
