What type of plastic are Lego building blocks made from?

Question

BlackTom AI · Accepted Answer

Question restatement: The prompt asks, 'What type of plastic are Lego building blocks made from?' and provides five possible material options.

Option 1: Polycarbonate. While polycarbonate is a strong plastic used in some impact-prone applications, LEGO bricks are not made from it. The material typically has higher transparency and different processing characteristics, but it does not align with LEGO’s standard brick performance, colorability, and manufacturing history. This makes this option incorrect.

Option 2: Polyethylene terephthalate (PET). PET is widely used for beverage bottles and textile fibers, valued for clarity and barrier properties, but it is not used for LEGO bricks. Its processing and material properties don’t match LEGO’s requirements for tight dimensional tolerances and color stability in molded bricks, so this choice is not accurate.

Option 3: Acrylonitrile butadiene styrene (ABS). This is the classic LEGO brick material. ABS provides a strong, impact-resistant, and relatively stiff plastic that is easy to mold with precise tolerances, holds color well, and can be mass-produced with consistent quality. These properties make ABS the correct description for LEGO bricks in mainstream manufacturing.

Option 4: Phenol formaldehyde resin. Also known as Bakelite, this resin is an older thermoset polymer that is brittle and hard to mold into the flexible, reusable bricks LEGO is known for. Its brittleness and processing characteristics make it unsuitable for the LEGO brick design, so this option is incorrect.

Option 5: Poly(methyl methacrylate) (PMMA). PMMA is an acrylic resin known for clarity and beauty, but it lacks the combination of toughness and impact resistance that LEGO bricks require. It does not align with LEGO’s widely used production material, rendering this choice incorrect.
