## Mechanical Strength and Structural Performance of Extruded Strip ### Tensile Strength and Flexural Modulus: What to Measure in Extruded Profiles Tensile strength (MPa) and flexural modulus (GPa) are key indicators of extruded profile performance. Co-extruded profiles achieve tensile strengths up to 1,126 MPa, nearly double the 590 MPa typical of standard PVC. Flexural modulus values between 2.89–4.3 GPa reflect strong resistance to deformation, essential for structural applications like curtain wall systems. ### Impact Resistance Under Dynamic and High-Stress Conditions Modern extruded strips withstand impact forces up to 48 J/m² in laboratory testing, with performance closely tied to polymer composition. Dynamic stress simulations show co-extruded designs maintain integrity through over 10,000 cyclic impacts at 23 kN loads, while PVC profiles exhibit 18% higher crack propagation rates under the same conditions. ### Heat and Impact Resilience in Demanding Applications Thermoplastic elastomer-based strips retain 92% of initial impact strength at 80°C (176°F), compared to 67% for rigid PVC. This dual resilience is critical in automotive edge trim and industrial machinery guards exposed to daily thermal cycling. ### PVC vs Co-Extruded Profiles: Comparing Durability and Performance | Property | PVC | Co-Extruded | |------------------------|---------------------|---------------------| | Tensile Strength | 590-624 MPa | 1,060-1,130 MPa | | Impact Resistance | 16-21 J/m² | 36-48 J/m² | | Thermal Degradation | Starts @ 140°C | Delayed until 180°C | Data from recent polymer studies confirms co-extruded strips offer 73% longer service life in high-wear environments compared to single-material PVC.
