Description
Nylon is a member of the thermoplastic polyamide (PA) family, and is considered to be the first crystalline plastic. It was invented way back in the 1930’s but introduced for injection molding around 1943.
We all know nylon as a strong tough plastic. Why is nylon such a strong material? The basic strength lies in the electrical bonds between molecules. This is the same bond which occurs in nature in fibrous materials such as silk and animal tissue. Interestingly, the tensile strength of the muscle in your arm – at least those of us who have any muscle left – is very close to the tensile strength of nylon.
