What does ESC mean in PHYSICS
Environmental Stress Cracking (ESC) is a type of crack or fracture that occurs in polymeric materials after exposure to certain stresses and environmental conditions. It is an important factor to consider when selecting and designing materials for use in extreme environments. ESC works by weakening the material through the combination of stresses, such as stress concentration, temperature change, chemical attack, fatigue, abrasion or radiation. The weakened structure then succumbs to external loading and fails prematurely. This type of failure can be seen in products such as plumbing fittings, toys, medical implants and vehicle components.

Essential Questions and Answers on Environmental Stress Cracking in "SCIENCE»PHYSICS"
What is Environmental Stress Cracking (ESC)?
Environmental Stress Cracking, also known as ESC, is a form of plastic degradation that occurs when certain plastics are exposed to various environmental conditions. It can cause cracking or even complete failure of the affected material due to its susceptible nature to certain elements like heat, UV light, and chemical exposure.
What factors contribute to ESC?
There are several factors that can lead to Environmental Stress Cracking with the primary contributors being stress concentration caused by an object’s geometry, temperature changes, surface conditions, and prolonged exposure to specific chemicals like salts and acids.
Are there any materials or products more susceptible to ESC?
Yes, materials such as ABS (Acrylonitrile Butadiene Styrene), PVC (Polyvinyl Chloride), polyethylene terephthalate (PET) and polycarbonate (PC) are particularly vulnerable to this form of degradation.
How can ESC be prevented?
To prevent Environmental Stress Cracking from occurring on a product’s surface it is important to reduce stress concentrations by proper design techniques and avoiding possible sources of external contaminants. Furthermore, using robust and durable raw materials as well as properly pre-treating the parts before assembly will help increase resistance against environmental degradation.
What types of testing methods are used for evaluation in regards to ESC?
Common testing methods used for evaluation include accelerated aging tests that simulate worst-case scenarios in shorter periods of time while other testing methods uncover underlying issues related to chemical corrosion or temperature extremes which might eventually lead to ESC issues down the line.
How does a coating help protect against ESC?
Coating products with protective layers like special epoxies or lacquers help prevent exposure from being damaged by chemical compounds or physical damage caused by abrasion which could occur after extended use.
Are there any standards in place that dictate testing conditions for potential ESC issues?
Yes, industry standards such as ASTM D2093 and ISO 4892 detail laboratory test parameters for straw-blade tests and wet/dry cycle tests which are used for evaluating and determining susceptibility towards ESC occurrence among plastics materials through actual samples being analyzed against accelerated extreme conditions.
Final Words:
Overall Environmental Stress Cracking (ESC) is an important factor to consider when designing products that will be exposed to harsh environmental conditions. It occurs due to combined stresses on polymer materials resulting in premature failure if left unchecked or uncorrected during product design or manufacture stages. While understanding how ESC works is essential for successful product design it is usually easily avoided with proper attention paid during material selection and planning stages.
