What Can Weaken Plastic?

The most common cause of plastic parts to weaken is exposure of the plastic to sunlight. Plastics consist of long polymer chain molecules which are entangled together, The longer the polymer chains, the stronger the plasticA CASE STUDY The following case study is the property of Plastic Expert Group

Does Plastic Ever Go Away?

Generally, it takes many decades for plastics to degrade in the environment. Plastics degrade by oxidation and hydrolysis. Oxidation and hydrolysis are accelerated by heat and sunlight.  A CASE STUDY  The following case study is the property of Plastic Expert Group and cannot be copied or

Why Does Plastic Crack Over Time?

The two main reasons why plastic parts crack over time is due to natural aging and from exposure to chemicals. As plastics parts age, they get weaker and weaker.  A CASE STUDY  The following case study is the property of Plastic Expert Group and cannot be copied or distributed without prior

At What Temperature Does Plastic Become Brittle?

The strength of plastics decreases at cold temperatures. For example, polycarbonate (PC) is an extremely tough plastic at normal use temperature and is sometime used as “bullet-proof glass”. However, at very cold temperatures (-40F), PC becomes brittle and will shatter like regular glass if struck

Plastic Fatigue

June 24, 2022

Does Plastic Have Fatigue?

The plastic in rigid thermoplastic parts consists of long chain molecules entangled together like spaghetti noodles in a bowl of spaghetti. The strength of the plastic is directly proportional to the extent to which the polymer chains are entangled with each other. When a plastic part is placed
