Hindi + Urdu + English mix
For students, engineers, machinists

In this video, we explore Additives used in Thermosetting Plastics, a crucial topic in Polymer Engineering and Material Science.

Thermosetting plastics like epoxy, phenolic, and melamine are widely used in high-performance applications — but to achieve desired mechanical, thermal, and electrical properties, additives are mixed during formulation.

Here’s what you’ll learn in this video:
🔹 What are Additives? (Definition and role in thermosets)
🔹 Purpose of Additives – To improve processability, appearance, strength, flame resistance, and durability
🔹 Types of Additives –
 • Plasticizers → Flexibility improvement (2–10%)
 • Stabilizers → Prevent thermal & UV degradation (0.5–2%)
 • Catalysts/Accelerators → Speed up curing (1–3%)
 • Pigments & Dyes → Provide color (0.1–1%)
 • Flame Retardants → Improve fire resistance (5–20%)
 • Lubricants → Reduce friction during molding (0.5–1%)
🔹 Examples – Phthalates, Antioxidants, Zinc stearate, Titanium dioxide, Antimony trioxide, etc.
🔹 Uses – Electrical insulation, automotive components, adhesives, aerospace composites, kitchenware, coatings

This video will help engineering students, design engineers, and polymer learners clearly understand the purpose and function of each additive in thermosetting plastics.
