TR-90 material origins
TR-90, a thermoplastic material known for its clarity, durability, and lightweight properties, has its origins deeply rooted in the evolution of plastic manufacturing. The material is a type of polyurethane, which was first developed in the 1930s by German chemists. However, the specific formulation that would become TR-90 was not invented until several decades later.
The development of TR-90 can be traced back to the 1960s when the demand for high-performance plastics began to rise. During this period, researchers at the Eastman Chemical Company were experimenting with various polymer compositions in an effort to create a material that could withstand high temperatures and resist impact. Their efforts eventually led to the creation of a new polyurethane-based polymer that exhibited exceptional clarity and toughness.
One of the key innovations in the development of TR-90 was the use of a specific type of diisocyanate, which allowed for the creation of a polymer with a high refractive index and low birefringence. This resulted in a material that was not only clear but also resistant to scratching and cracking. Additionally, the use of a particular type of polyol in the polymerization process contributed to the material's excellent impact resistance and flexibility.
TR-90 was officially introduced to the market in the early 1970s and quickly gained popularity due to its unique combination of properties. It was initially used primarily in the eyewear industry for the production of high-quality, impact-resistant lenses. However, as the material's versatility became more widely recognized, it found applications in a variety of other industries, including automotive, aerospace, and medical devices.
Today, TR-90 continues to be a leading material in the plastic industry, valued for its exceptional performance characteristics and ease of processing. Its development represents a significant milestone in the history of plastic manufacturing, showcasing the power of innovation and the continuous quest for improved materials.
