Specific compressive strength, specific flexural modulus, and density were found to improve by introducing nanoclay in the polymer matrix. Whereas, tensile strength and modulus of elasticity showed some deterioration with the presence of nanoclay in the rigid PVC foam. On the other hand, impact strength and specific flexural strength did not show any significant changes.

How Strong is PVC Pipe? (With PVC Strength Charts)

10/08/2016  PVC pipe tensile strength can be measured by hanging weight from the pipe until it bends or cracks. As you can see from the chart to the right, tensile strength of PVC pipe increases as the size of the pipe increases. 8" PVC pipe of either schedule is extremely strong for how inexpensive it is. The smaller sizes are exponentially weaker, but can still hold a great
