1. What is "fluorescent yellow-green"?
First, let's disassemble this somewhat professional-sounding term: "fluorescent yellow-green".Fluorescence: It does not have its own light source, but can "glow" under ultraviolet or blue light.
Yellow-green: It is a bright color between yellow and green, often called "fluorescent green", or "yellow-green fluorescence".
This color is particularly bright, and the feeling of "glowing" can be clearly seen even in the daytime. If you have seen athletes' safety vests, night running bracelets, or some cool trendy headphone cables, then you probably know what color this is.
2. Why is it used in "injection molding"?
Let's take a look at "injection moulded", which is injection molding.Injection molding is a common plastic processing method. Its process is a bit like baking:
1. Heat the plastic particles (usually thermoplastic resin) until they become soft;
2. Inject the softened plastic into the mold;
3. After cooling, open the mold and the plastic will be formed!
This method is efficient and has good molding accuracy. It is suitable for mass production of complex objects. For example, many of our common plastic water cups, headphone shells, game controllers, and even building blocks are made by injection molding.
Add fluorescent pigments to the plastic used for injection molding, and you can make eye-catching plastic products!
3. The role of fluorescent yellow-green injection molding materials
Attract attention:Fluorescent yellow-green is a color with a strong visual impact. Even if it is placed in a pile of objects, it will stand out. This effect is very useful in many fields:
Toy design: Make it easier for children to find and like it;
Sports goods: Like fluorescent sports water bottles, running bracelets, etc., to improve visibility;
Electronic products: For example, headphone cables, power cords, etc. are easier to find;
Fashion items: For example, fluorescent green shoelaces, mobile phone cases, etc., are at the forefront of fashion.
Improve safety：
In some occasions where you need to be "seen", fluorescent colors are a good way to improve safety. For example:
Construction site equipment: Wearing a fluorescent green helmet, you can be spotted at a glance;
Night supplies: Like riding lights, reflective strips, etc., they are particularly bright at night;
Emergency equipment: Such as first aid kits, survival whistles, etc., bright colors can come in handy at critical moments.
Create a sense of technology and the future：
Fluorescent colors often give people a sense of "technology", "alien" and "future". Many props in science fiction movies or games have similar color schemes. Using this color can make the product look more "high-tech" and more designed.
4. How is fluorescent yellow-green added to plastic?
To make injection molded plastics fluorescent yellow-green, special fluorescent masterbatch or fluorescent pigment is needed.Fluorescent masterbatch：
This is a particle made by mixing fluorescent pigments into a plastic base in advance. When using it, just mix it into the original plastic in proportion. It has these advantages:
Good dispersion: uniform color;
High ease of use: not easy to dirty the machine;
Stable color: long-lasting luminous effect.
Fluorescent pigments
Fluorescent pigments are powdered and divided into soluble and insoluble types. Suitable for occasions that are cost-sensitive but require high operating technology. Special attention should be paid to:
Temperature resistance: The temperature during injection molding is generally between 180°C and 250°C, and the pigment must be resistant to high temperatures;
Light stability: It cannot fade too quickly when used in the sun;
Compatibility: It must be compatible with plastic materials, otherwise uneven particles or color spots are likely to occur.
5. Practical application cases of fluorescent yellow-green plastics
Building blocks:Building blocks use fluorescent materials, which are brightly colored and attract children's attention.
Soles of high-end running shoes:
Some international brands of sports shoes use fluorescent green TPU (thermoplastic polyurethane) as soles, which are not only beautiful but also improve night visibility.
Gaming equipment accessories:
Transparent keycaps and handle shells of mechanical keyboards, for example, become cooler under light after using fluorescent injection molding.
Smart wearable products：
Smart bracelets, sports watches, etc. often use fluorescent green plastic straps, which have a sense of technology and night vision.
Sixth, environmental protection perspective: Can fluorescent plastics be sustainable?
Many people worry: "Such bright colors, will they be bad for the environment?" This is a good question!
Modern fluorescent plastic materials are developing in the direction of environmental protection, such as:
1. Use non-toxic, heavy metal-free fluorescent pigments;
2. Use recyclable plastic substrates (such as PP, PET);
Consider easy recycling or disassembly when designing.
