3M company reflective powder

Reflective powder is made of one kind of glass tiny bead powder. It has three refractive indexes, namely: ND ≥ 1.90, ND ≥ 1.93, ND ≥ 2.2 Specification is from 100 head to 500 head. You can choose silver-gray color or white color.

Reflective principle: When light shines the tiny bead surface, it’s focused on the special reflector of tiny bead’s focus for its high refraction role. Reflector makes light reflect again to the light source nearby through transparent tiny bead, so at the light source we can see the very bright reflected light. After the calculation according to the complicated optical formula, we can see that only when tiny bead’s refractive index exceeds 1.9, good reflective effect comes.

Reflective powder is core component to produce reflective cloth, reflective leather, reflective patch, reflective paint and other new types of composite materials with luminous function. It can give rise to strong reflection effect for its reflective property.
