Eraser, PVC-free

Technical Parameter

Details

Material

PVC - free materials, such as natural rubber or synthetic rubber alternatives without polyvinyl chloride, ensuring environmental safety and non - toxicity.

Erasing Efficiency

The ability of the eraser to remove pencil marks. It should be able to cleanly and effectively erase HB pencil marks without leaving smudges or residues on the paper.

Abrasiveness

The degree to which the eraser wears down the paper surface during erasing. A high - quality PVC - free eraser should have low abrasiveness to prevent damage to the paper, especially when using thin or delicate papers.

Durability

The length of time the eraser can maintain its erasing performance. During normal use, it should not easily crumble or deform and should be able to withstand repeated erasing actions.

Shape and Size

Available shapes (e.g., rectangular, round, triangular) and sizes that are convenient to hold, whether for general writing and erasing or for more precise work in art or drafting.

Color

The color of the eraser, which may be the natural color (such as that of the base material) or may be tinted with non - toxic dyes to meet aesthetic or identification needs.

Flexibility

Some erasers are designed to be flexible, which is useful for conforming to irregular surfaces or for more precise erasing. Flexibility should not affect erasing efficiency or durability.

Odor

Due to the use of PVC - free materials, the eraser should have almost no unpleasant odor. Any odor should not be offensive and should not cause discomfort during use.
