Introduction to LEGO Plastic
History of LEGO Plastic
LEGO has a rich history when it comes to plastic. The company started using plastic as the primary material for their bricks in the late 1940s. This decision revolutionized the toy industry, as plastic offered numerous advantages over traditional materials like wood and metal. The introduction of plastic allowed LEGO to create interlocking bricks that were durable, versatile, and easy to manufacture. Plastic became the foundation of LEGO's success and has remained the go-to material for their products ever since.
In the early years, LEGO bricks were made from cellulose acetate, a type of plastic derived from wood pulp. However, the company soon realized that cellulose acetate was not suitable for long-term use, as it was prone to warping and discoloration. This led to the development of a new plastic material called acrylonitrile butadiene styrene (ABS), which became the standard material for LEGO bricks in 1963. ABS plastic offered improved durability, color stability, and compatibility between different LEGO sets.
Today, LEGO continues to innovate and improve their plastic materials, ensuring that their bricks meet the highest quality standards. The company invests heavily in research and development to find sustainable alternatives and reduce the environmental impact of their plastic production. LEGO's commitment to plastic innovation has made their bricks iconic and beloved by millions of people around the world.
