The material continues to deform indefinitely at an ever decreasing rate. If the load is high enough, the material may yield or rupture.Engineering Properties of Polyethylene What is the difference between PP and HDPE?What is the difference between PP and HDPE?While PP has many similarities to HDPE, there are some key differences. First, the density of PP is around 0.900 g/cc, while HDPE is more than 0.941 g/cc. This is in part due to PP being generally a more amorphous (less crystalline) material than HDPE. PP is a stiffer material than HDPE, which makes it desirable from a pipe handling standpoint.Chapter 2 HDPE Propylene Materials - Plastics Pipe Institute
What is the effective modulus of elasticity?What is the effective modulus of elasticity?The effective modulus of elasticity is significantly reduced by the duration of the loading because of the creep and stress relaxation characteristics of PE. An instantaneous modulus for sudden events such as water hammer can be as high as 150,000 psi at 73°F (23°C).Engineering Properties of Polyethylene
