Frequently Asked Questions
ASTM D2287 evaluates mechanical properties of non-rigid vinyl chloride materials, particularly tensile strength and elongation. It ensures that flexible PVC products meet performance requirements for durability, flexibility, and structural integrity in various applications.
Tensile testing determines how the material behaves under stretching forces. It provides critical data on strength and flexibility, helping ensure the material can withstand mechanical stresses during use without failure.
Elongation at break indicates how much a material can stretch before failure. Higher elongation values reflect better flexibility and ductility, which are essential for applications requiring repeated bending or deformation.
Factors include plasticizer content, formulation, processing conditions, temperature, and aging. Variations in these parameters can significantly influence strength and flexibility characteristics.
Stress–strain curves provide detailed insight into material behavior under load, including elasticity, yield point, and failure characteristics, enabling comprehensive evaluation of performance.
