What is the tensile strength of the color steel plate protective film
2025-07-16
Tensile Strength of Color Steel Plate Protective Film
The tensile strength of color steel plate protective film is a key indicator measuring its resistance to fracture under tension, directly affecting reliability during construction, transportation, and use.
High-quality protective films typically exhibit tensile strength between 10-30MPa, varying by material composition, thickness, and manufacturing processes.
Material Comparison
- Polyethylene (PE): Mainstream choice with 12-20MPa tensile strength, offering balanced flexibility and tear resistance
- Polyvinyl Chloride (PVC): Higher strength (15-25MPa) but reduced flexibility, ideal for high-protection scenarios
- Multi-layer co-extruded films: Advanced products reaching 20-30MPa while maintaining ductility
Testing Standards
Tests should comply with GB/T 1040.3-2006 under controlled conditions:
- Standard temperature: 23°C
- Optimal elongation range: 150%-300%
- Must withstand operational stresses without fracture
Performance Balance
Critical considerations for practical applications:
- Sufficient strength to prevent damage during handling
- Moderate adhesion for clean removal post-use
- Adaptation to environmental conditions and storage duration
Proper tensile strength prevents surface scratches and contamination while ensuring the film remains removable without residue.
