In terms of strength, PVC (polyvinyl chloride) is generally stronger than resin. This is due to the molecular structure and composition of PVC, which allows it to withstand higher tensile and compressive forces compared to resins. According to a study published in the Journal of Applied Polymer Science, the tensile strength of PVC can range from 50 to 70 MPa, while the tensile strength of typical resins is often around 20 to 40 MPa. This significant difference in tensile strength is primarily attributed to the presence of chlorine in PVC, which increases its rigidity and strength. Additionally, PVC has a higher modulus of elasticity, meaning it can deform less under stress, contributing to its overall strength.
