SCIENCE | FACTS | BEYOND | HISTORY | on Instagram: "What looks like a simple plastic pipe is actually the result of precision chemistry, heat control, and engineering discipline. 🔧 PVC pipes are designed to survive pressure, corrosion, heat, cold, and decades underground—and it all starts at the molecular level. Here’s how the process works step by step 👇 • PVC resin powder is mixed with stabilizers, lubricants, and impact modifiers • The blend is fed into an extruder, where intense heat melts
