"I am a high-consistency rubber (HCR), which means I start as a thick, doughy putty. But after curing, I become a solid, elastic part. My name ‘450’ means I am ultra-high temperature resistant—up to 260°C (500°F) continuously, and I can survive brief spikes to 315°C (600°F)."

Plastic Pete chimed in. "I’m cheap and flexible! But... at 150°C, I melt into a gooey puddle. Sorry."

A young engineer named Lena burst in. "I have a problem," she announced. "I need to build a medical device that goes inside a sterilization machine. The temperature hits 200°C (392°F), and the device will be blasted with steam, ozone, and harsh chemicals."

Everyone turned to the clear tube. "What about you, 450?" Lena asked.
