What are the durometer hardness properties of the bin’s materials?

The durometer hardness of bin materials is a critical factor in determining their durability, flexibility, and suitability for specific applications. Durometer hardness measures a material's resistance to permanent indentation, typically using scales like Shore A or Shore D, depending on the material's rigidity.

For plastic bins, common materials like polyethylene (PE) and polypropylene (PP) often fall within the Shore D scale, ranging from 50 to 70, indicating moderate to high hardness. These values ensure the bins can withstand heavy loads without cracking while retaining some flexibility.

Rubberized or softer bins may use the Shore A scale, with values between 60 and 90, offering better impact resistance but less rigidity. Understanding these properties helps in selecting the right bin for industrial, commercial, or household use, balancing toughness with practicality.

Higher durometer ratings generally mean greater wear resistance, but excessively hard materials may become brittle. Manufacturers often optimize hardness to ensure longevity without compromising functionality. Testing methods like ASTM D2240 standardize these measurements, providing reliable data for material selection.

In summary, the durometer hardness of bin materials directly influences their performance, making it a key consideration for buyers and engineers alike.
