The mechanical properties of
recycled plastic Low Density Polyethylene Resin can vary depending on several factors, including the source of the recycled material, the recycling process employed, and any additives or treatments used during recycling. Generally, recycled PE retains many of the mechanical properties of virgin PE, but there may be some differences. Here are the key mechanical properties:
Tensile Strength:
Tensile strength measures a material's resistance to a force pulling it apart. Recycled PE typically exhibits tensile strength comparable to virgin PE. However, variations can occur based on the recycling process and the specific conditions of the recycled material.
Elongation at Break:
Elongation at break refers to the ability of a material to stretch before breaking. Recycled PE may have similar elongation characteristics to virgin PE, but the degree can be influenced by factors such as the presence of contaminants or changes in molecular structure during recycling.
Flexural Strength:
Flexural strength measures a material's ability to resist deformation under load. The flexural strength of recycled PE is generally in line with that of virgin PE, but adjustments may be necessary based on the specific recycled material and processing conditions.
Impact Resistance:
Impact resistance is crucial for applications where the material is subjected to sudden or repeated impacts. Recycled PE can exhibit good impact resistance, but the presence of contaminants or variations in molecular structure may affect this property.
Hardness:
Hardness measures a material's resistance to indentation or scratching. Recycled PE typically has a hardness level comparable to that of virgin PE, but the specific hardness may vary based on the recycled material and processing parameters.
Modulus of Elasticity:
The modulus of elasticity, or Young's modulus, represents a material's stiffness. Recycled PE generally maintains a modulus of elasticity similar to that of virgin PE, but variations may occur based on factors like molecular chain length and processing conditions.
Creep Resistance:
Creep resistance refers to a material's ability to resist deformation over time when subjected to a constant load. Recycled PE may have creep resistance comparable to virgin PE, but it can be influenced by the material's history and processing conditions.
Fatigue Resistance:
Fatigue resistance is important for materials subjected to cyclic loading. The fatigue resistance of recycled PE can be influenced by the recycling process and the presence of any structural changes in the material.
