What is high temperature laser glitter powder

Different from ordinary decorative materials, high-temperature laser glitter powder(Heat resistant holographic glitters) is a tiny particle. It can maintain its shining properties even in extreme environments. This type of glitter is becoming the latest magic weapon to increase product added value.

Re-understanding high temperature laser glitters

Imagine a material that can maintain bright colors at high temperatures of 280°C, 300°C, or even 350°C. It does not fade in strong acid and alkali environments, and can present a dreamy rainbow effect as the light angle changes.

Yes, it is just modern high-temperature laser glitter powder.

Take the products of iSuoChem, a leading brand in the industry, as an example. Its aluminum-based glitter powder uses uses nano-imprinting technology to create a precise optical structure on each particle of only 0.04mm in size.

The uniqueness of this glitter material lies in its "three high" characteristics:

High temperature resistance: continuous tolerance to high temperature of 280-350℃.

High reflectivity: more than 50% higher reflectivity than traditional glitter flakes.

High stability: Color is stable in different shipping batches.

Why choose high temperature series aluminum-based laser glitters?

Engineer Li, who works at a cosmetics packaging factory, told us: "In the past, when we used ordinary PET glitter powder, it would deform and lose color once the injection temperature exceeded 180°C. Now that we have switched to aluminum-based products, not only has the yield rate increased, but the flash effect is also more lasting." This is the key reason why more and more high-end manufacturers are turning to high temperature resistant aluminum-based laser glitter powder.

Compared with traditional glitter materials, the advantages of high temperature resistant aluminum-based glitters are obvious:

More resistant to high temperatures: iSuoChem's glitter product clearly states that the temperature range is 280 ℃, 300℃ and 350℃(aluminum model), which is far higher than ordinary PET, PE, PVC plastic powder (130 or 180℃). This product is particularly suitable for high-temperature injection molding (such as the processing temperature range of ABS, PC, PP and other plastics).

More eye-catching: The product emphasizes the holographic laser effect, which achieves dynamic rainbow colors through patented diffraction grating technology rather than simple mirror reflection. Its reflectivity is more than 50% higher than that of ordinary glitter powder, and it has angle-dependent color change characteristics.

More durable: Excellent scratch resistance and longer service life.

Injection molding process parameters reference

However, it should be noted that aluminum-based materials have a relatively high density (1.8-2.2 g/cm³) . They are prone to sedimentation in suspension systems. So special attention should be paid to the dispersion process when using them.

Skills and experience in practical application

At a factory in Shanghai that specializes in the production of automotive interiors, technical supervisor Manager Wang shared their experience: "We found that adding 0.8% of 0.25mm glitter powder to PC material has the best effect, which can ensure fluidity and present a uniform starlight effect."

According to industry experience, when using high-temperature laser glitter powder, please pay attention to:

Adding ratio: usually controlled between 0.3%-1.2%

Particle size selection: iSuoChem provides standard particle sizes of 0.008 mm (8 microns) to 3 mm, of which the main models are 0.04 mm and 0.25 mm. Users can choose according to the size of the injection molded part or the thickness of the coating. 0.04mm is recommended for thin-walled parts and 0.25mm for thick-walled parts.

Process adaptation: It is best to use a screw injection molding machine to ensure uniform dispersion

Ms. Lin, a designer at a cosmetic packaging company in Guangzhou, specially reminded: "We have done tests and found that using glitter powder with transparent PMMA material can save nearly 30% of the amount compared with using white substrate."

Industry application case analysis
Case 1: High-end car interior
A German car brand uses 0.15mm champagne gold laser glitter powder in the instrument panel decoration of its new models. It not only passes the temperature cycle test from -40℃ to 120℃, but also greatly enhances the luxury of the interior.
Case 2: Smart home appliance panel
A Korean appliance manufacturer incorporates 0.04mm ice blue glitter powder into the panel of its sweeping robot, combined with LED lighting effects to create a futuristic product image and help the product stand out from the competition.
Case 3: Luxury Packaging
The latest limited edition packaging of a French perfume brand uses customized heart-shaped laser glitter powder and achieves a gradient color effect through a special printing process, which has become a hot topic on social media.

How to choose high-quality products
Faced with the dazzling array of glitter products on the market, we recommend considering the following dimensions:
Certification qualification: Check whether it has international certification such as iSO, SGS , etc.
Sample testing: Require suppliers to provide physical samples for process verification.
Technical support: Choose a professional supplier who can provide specific application solutions.
Customization capability: For special projects, it is necessary to confirm whether the manufacturer can provide customized services for particle size and shape.

It is worth mentioning that professional glitter suppliers like iSuoChem usually provide sample services to facilitate customers to conduct small batch testing first. This is very important for ensuring the stability of large-scale production.

Solutions to common problems

Future development trends

With the advancement of manufacturing technology, high temperature laser glitter powder is developing in three directions:

More refined: The appearance of 0.008mm ultra-fine particles makes the surface effect more delicate

Smarter: Intelligent products such as temperature-controlled and light-controlled products are under development

More environmentally friendly: The application of biodegradable materials (So far, iSuoChem have bio-degradable glitters which meet the requirements of European market) will expand to cosmetics.

As Professor Zhang, a materials expert, said: "In the future, glitter powder will not only be a decorative material, but also a functional material, playing a greater role in anti-counterfeiting labels, optical devices and other fields."

In this era of appearance economy, high temperature laser glitter powder is reshaping the possibility of product appearance design with its unique charm. Whether you want to improve the grade of your product or create a differentiated competitive advantage, this small glitter particle may become the best choice for your market to increase the added value of your product.
