Main Raw Materials:

Rare earth long-lasting afterglow night-light powder, polystyrene resin

1. Nightlight powder is a high-tech self-luminous product activated by rare earth metal elements and alkaline earth aluminum sulfates. It can withstand temperatures of about 800 degrees. Its function is to absorb light and store light to emit light. It absorbs light in bright places (more than half an hour), and emits light in dark places. It has a strong ability to absorb short-wave visible light with a wavelength of less than 450 nanometers. By absorbing various natural or artificial light, it achieves the function of self-luminous in the dark state, and can be used repeatedly. This luminous material has a high initial brightness of 2-3 hours, and the light emission curve is smooth. The afterglow duration can reach 8-10 hours.

Poly(styrene) resin (see detailed information on Baidu Encyclopedia)

Polystyrene, abbreviated as PS, refers to a polymer made from styrene monomers through free radical polymerization. In Japanese, it is known as polystyrene. It is an odorless and transparent thermoplastic plastic with a glass transition temperature above 100°C, making it often used to create various disposable containers that can withstand boiling water and single-use foam food boxes. Regular polystyrene resin is an amorphous high molecular polymer with random arrangements of large-volume benzene rings in its side chains, which determine the physical and chemical properties of polystyrene, such as high transparency, high rigidity, high glass transition temperature, and brittleness. Expandable polystyrene is made by immersing low-boiling physical foam agents in regular polystyrene, which bubbles up during processing and is used to make foam plastic products. High-impact polystyrene is a copolymer of styrene and butadiene, with butadiene as the dispersed phase, which improves the material's impact strength, but the product is not transparent. Isotactic polystyrene is an isomeric structure produced using metallocene catalysts, and is a new variety of polystyrene with good performance, which belongs to engineering plastics.

The night-light stones produced by our company are exported to the United States, Australia, Russia, and various countries in Europe, and are deeply favored by foreign customers.

Product dimensions (the following dimensions and weights are reference values)

Size: About 2CM

Weight: About 2.3 grams

Because the shape of the stones is irregular, the above dimensions are only estimated values, and the weight is the sample weight. The data is for reference only. The shape of the stones will be shipped randomly when shipping. Light emission principle:

The principle of night-light stones is that after being stimulated by visible light such as sunlight or artificial light, they absorb and store energy. They can then emit light naturally in the dark for a long time. The product can be re-absorbed and re-emitted repeatedly, with a lifespan of over 15 years.
