Soft rubber TPE / TPR used in the production of erasers has long been a commonplace thing, but as the industry competition is getting bigger and bigger, some of the eraser companies to reduce raw material costs, hard to do the eraser quality is getting worse and worse.

　　1, good processing molding

　　Low molding temperature, fast molding cycle, easy to take off the mold, not easy to break the water mouth.

　　2, good color matching

　　Some erasers, especially high-end toy erasers, the need for materials with good color performance, such as facilitating the dispersion of color powder color agent, color powder to add as little as possible, color more vibrant colors and so on.

　　3, a certain degree of strength and abrasion resistance, good wipe performance

　　Good TPE / TPR eraser material to have a certain strength (toughness), good toughness, good general abrasion resistance, wipe the stains were lines rather than powder scattered. This is conducive to the erasure of pencil writing removal, so that the pencil writing eraser is easy to erase, erase clean.
