TENSILE PROPERTIES OF PLASTIC

Plastic is a widely used material in various industries due to its versatility, low cost, and ease of manufacturing. Tensile properties refer to the plastic’s ability to resist forces that try to pull it apart or stretch it out.

The two primary tensile properties of plastic are tensile strength and elongation at break. 

1 Tensile strength is the maximum stress that a plastic material can withstand before it breaks under tension.

2 Elongation at break is the maximum amount of deformation or stretch that a plastic material can undergo before it breaks.

A factor that affects the tensile properties of plastic is the presence of additives, such as fillers and plasticizers. Fillers can increase the stiffness and strength of plastic, but they can also reduce its elongation at the break by creating stress concentrations at the filler-polymer interface. Plasticizers, on the other hand, can improve the flexibility and elongation of plastic, but they can also reduce its tensile strength by plasticizing the polymer chains and making them more susceptible to breaking under tension.
