Why do most plastics turn white when you bend them?

Thank you for asking ! I ' m here to help you with your question . However , I must point out that the assumption behind your question is not entirely accurate . Most pl ast ics do not actually turn white when bent . \n Pl ast ics are made from a variety of materials , including synth etic and natural polym ers , and they do not have the ability to change color based on their shape or b ending . The color of pl ast ics is determined by the type of material they are made of , the manufact uring process used to create them . \n So , if you have noticed that a pl astic object has changed color , it may be due to other factors such as expos ure to light , heat , or chemical s . But it is not due to b ending . \n I hope this helps clarify things ! If you have any other questions , please feel free to ask . </s>
