Plastics

 

Plastics are of two main types: hard and soft. Plastics of first type (hard) aren’t easy to melt and therefore, are useful for radios different kinds of electrical articles. This type of plastic is often breakable. Plastics of the second type (soft) aren’t breakable and we can bend them. They are useful for pipes and children’s cups but these are easy to melt.
