What kind of luminous powders should I use for injection molding?

For better performance of injection molded products, waterproof luminous powder can also be used, which has been specially treated for coating. The difference from normal luminous powder is that the luminous waterproof powder is easily boil in the aqueous material to lose the luminous effect.

The luminous waterproof powder is not limited by the environment in the application, can maintain good luminescence performance, and service life is more than 20 years. The injection molding uses the yellow-green waterproof luminous powder WP-4 which has a finer particle size, but sometimes the 39 luminous oily powder series can be used due to low cost and process requirements.

Of course, since injection molding, it is various kinds of plastic raw materials are raw materials, so the same kind of plastic luminous material (such as luminous plastic master) can be mixed with raw materials to the friction between the luminous powder and the solve injection molding machine. The black problem solves the waterproof problem easily, once and for all. The advantage of injection molding is that the same plastic type can reduce the solidification at high temperature, friction and cost-effective. The disadvantage is that the price is more than a dozen pieces than the ordinary luminous powder. It can be put into production according to the actual situation.
