8 Surprising Facts About Plastics

Modern running shoes contain special plastic foams and carbon plates. They store energy, improve running efficiency and enable peak performance. Some models are now so high-performance that sports associations have introduced rules regarding sole height and carbon plates.

Why this matters: Material innovations in plastics can influence sporting performance to such an extent that they even lead to new competition rules.

A single PET bottle consists of countless interconnected plastic molecules. The material is lightweight, sturdy and flexible at the same time – properties that make PET an important packaging material worldwide.

Why this matters: Even seemingly simple everyday products are based on complex materials research and precise processing technology.

Many components in modern vehicles are now made of plastic rather than metal. This has made cars significantly lighter. This saves fuel or increases the range of electric vehicles. Today, plastics account for around 15–20% of a vehicle’s weight.

Why this matters: Lightweight construction plays a central role in more sustainable mobility and more efficient vehicles.

The famous LEGO brick is made from ABS plastic, a particularly robust and durable material. The basic principle has remained virtually unchanged since 1958. That is why old and new bricks still fit together perfectly today.

Why this matters: The durability of modern plastics ensures that toys function reliably for decades.

Today's long-haul aircraft consist of over 50% plastic-based composites. These materials combine low weight with high stability and help to reduce fuel consumption and emissions.

Why this matters: Without lightweight plastic composites, modern, fuel-efficient aircraft would be virtually impossible.

Plastic also played a key role in the Apollo 11 mission in 1969: Neil Armstrong's helmet was made of sturdy polycarbonate. The material was lightweight, impact-resistant and offered clear vision at the same time.

Why this matters: Plastics are used even under extreme conditions – even in space.

In Germany alone, tens of thousands of people work in plastics processing – from machine operation and materials development to quality control. The industry combines technology, sustainability and modern production.

Why this matters: The plastics industry offers a wide range of career paths for people with a diverse range of interests and talents.

Elena Blume has been writing for various industry magazines for eight years and joined the K-Mag editorial team in 2021. She is particularly interested in topics related to innovative plastics solutions that contribute to sustainability and address current challenges relevant to industry and society.
