Number 2 – High-Density Polyethylene (HDPE)
Created in 1953 this plastic was made using catalysts and low pressure to create a high-density polyethylene.

The professionals behind https://shapesplastics.com/ explain that it is a strong and rigid material and is easily processable. This means that it is perfect for cutting, drilling, and even routing.
Due to the easily processable nature of HDPE, it is also the most commonly recycled plastic as it will not break under exposure to extreme temperature. Unfortunately, only around 12% of all HDPE products created in a year are recycled.
