It’s essential to know the temperature at which LEGO® bricks melt and the ideal storage conditions to ensure their longevity.

LEGO® Firefighter Minifigure In Front Of Small Fire

LEGO® bricks are made from a thermoplastic known as acrylonitrile butadiene styrene (ABS), which is a robust and durable material. ABS melts at temperatures between 190 to 260 degrees Celsius (374 to 500 degrees Fahrenheit). At these temperatures, the plastic begins to lose its structural integrity and may deform or become unusable. Therefore, it is crucial to keep your LEGO collection away from extreme heat sources like radiators, heaters, or direct sunlight, as these can cause bricks to warp or become discolored.

Can LEGO® Melt In A Hot Car?

I wouldn’t say melt entirely, but warp and become discolored and brittle? Absolutely. LEGO® is not meant to be stored above 104F or 40C – anything above these temperatures and the plastic can become warped and puts your bricks and minifigs at risk. You should always properly store your LEGO®.

How Do You Make Sure Your LEGO® Pieces Don’t Melt?

For optimal storage and safekeeping, it is recommended that you store your LEGO® bricks in a cool, dry place, ideally at room temperature (20-22 degrees Celsius or 68-72 degrees Fahrenheit). This temperature range ensures that your LEGO® collection remains in prime condition, avoiding any warping or color degradation. Additionally, maintaining a stable environment with low humidity can further preserve the bricks, preventing any moisture-related damage.
