High-temperature environments require glitters that won’t lose color, curl, or degrade. Our heat resistant glitter is engineered for consistent shine—even when exposed to elevated temperatures. We serve global wholesalers, packaging factories, injection molders, and craft supply brands with reliable glitter that performs under heat.
Heat resistant glitter refers to polyester-based glitter that maintains its shape and color when exposed to higher temperatures.
Often used in processes like heat press vinyl (HTV), injection molding, candle-making, or automotive interiors, this glitter is specially treated or selected for thermal stability.




Whether glitter fades depends on temperature, duration, and the application context. For example, exposure to 180°C for 5 seconds during heat transfer is manageable, but extended heat over 220°C in molding may affect color on lower-grade materials. Always test in your specific environment.

We’ve supplied heat stable glitter to global manufacturers for years.
Our polyester base glitter can resist temperatures up to 230°C under short bursts, making it ideal for plastic molding, textile pressing, or craft projects.
We provide real test reports, flexible MOQ, and rich color choices for professional-grade results.
Used on clothing, textiles.
For molded plastic parts with embedded glitter.
Withstand wax-pour temperature without bleeding.
Glitter embedded into resin parts or coatings.
Home vinyl projects or packaging films.
Not all heat-resistant glitter performs equally in real production. While ours is tested up to 220°C, some industries face added stress from pressure, curing, or laser heat. If your process involves any of the following, make sure your glitter holds up — not just in theory, but on the line.
Injection molding involves high temperature and high-pressure conditions, typically between 180°C to 250°C. Not all glitter can survive the thermal shear force during plastic extrusion or mold filling.
What can go wrong:
Glitter turns black or melts
Pigment fades or bleeds into the plastic
Final product shows uneven color
Our recommendation:
Choose PET glitter with double-coated pigment layers and proven thermal stability ≥220°C. Particle size should be controlled to avoid clogging injection nozzles.
In candle pouring or wax tablet making, glitter is often used inside or on the surface. But direct exposure to melted wax (~80–100°C) can still cause regular glitter to lose shine or leach color into the wax.
What can go wrong:
Glitter loses sparkle after solidification
Color migrates, especially with essential oils
Potential safety concerns with non-certified pigments
Our recommendation:
Use high-purity PET glitter that is solvent-resistant and heat-tested in wax-based environments. External coating types (holographic, metallic) should be confirmed safe for wax use.
For label decorations or logo stamping using heat presses, temperatures often reach 160–200°C, sometimes combined with pressure. Poor-quality glitter may deform or flatten.
What can go wrong:
Glitter flakes get crushed or flattened
Residue remains on machinery
Our recommendation:
Use glitter with anti-static, anti-flattening coatings, and confirm pressure resistance during dry press tests.
Products involving powder coating or heat-curing adhesives often undergo oven baking. These processes may operate between 180–220°C for extended periods (5–15 minutes).
What can go wrong:
Glitter chars or discolors
Smell of burning plastic
Color shifts under extended heating
Our recommendation:
Select glitter certified for baking-grade thermal cycles, with no odor emission and UV-resistant pigment to retain original sparkle.
In masterbatch production, glitter is mixed into plastic resins and pre-compounded. The extrusion temperatures can reach 230°C+, and shear forces are extreme.
What can go wrong:
Glitter deforms or turns into sludge
Particles break apart, losing effect
Overheating causes smoke or discoloration
Our recommendation:
Use heat-resistant PET glitter in pellet form, preferably with high flow resistance and fine granularity control. Avoid recycled-content glitters.
When using laser marking or cutting equipment, if bright powder is added to the surface of the workpiece (such as metal tags, nameplates, or decorative products), high-energy lasers and high temperatures will instantly act on the surface of the bright powder, causing carbonization, smoke marks, or blistering.
What can go wrong:
Glitter reacts to laser heat, leaving burnt edges
Color gets damaged under laser pulses
Generates smoke or residue that affects precision
Our recommendation:
Use laser-compatible glitter, tested under short pulse or CO₂ laser exposure, with minimal reflectivity to reduce burn risk. Avoid metallic glitters or PVC-based material in laser processes.
| Use Case | Typical Temperature | Recommended Glitter |
|---|---|---|
| HTV printing | 150–180°C | High-grade polyester glitter |
| Plastic injection mold | 180–230°C | Metallic heat resistant glitter |
| Candle decoration | 60–90°C | Colorfast solvent glitter |
| Resin curing oven | 110–160°C | Holographic polyester glitter |
Note: Color fastness varies by pigment. Always test in actual environment.
Unlike standard craft glitter, which curls or melts under heat, heat-resistant glitter has a more stable base film—typically PET or specially coated polyester. These glitters resist curling, bleeding, and melting during short-term high-heat exposure, maintaining color brilliance even under pressure.
