SMC Properties for Electrical Insulation
Electrical Insulation Performance
You need electrical insulation that keeps you safe and your equipment working. Sheet moulding compound gives you strong protection because it does not conduct electricity. Union Composites uses fiberglass reinforcement and high-performance resins in every product. These materials help the compound block electrical flow and keep your devices safe.
Fiberglass reinforcement adds strength and stiffness.
High-performance resins boost insulation properties.
The compound stays strong even in humid conditions.
It does not let electricity pass through, so you stay safe.
You can see how well sheet moulding compound performs compared to other materials:
Property | Bulk Molding Compound (BMC) | Sheet Molding Compound (SMC) |
|---|---|---|
Dielectric Strength | 12 – 20 kV/mm | 10 – 18 kV/mm |
This high dielectric strength means your equipment can handle high voltages without breaking down. The compound also resists tracking and arcing, which protects sensitive parts like busbars and insulators. Because it keeps its shape and size, you get reliable performance in every use.
Note: The dimensional stability of sheet moulding compound helps your electrical systems work well, even when exposed to moisture, dust, or UV light.
Thermal and Flame Resistance
You want your electrical equipment to resist heat and fire. Sheet moulding compound stands out because it can handle high temperatures and stop flames from spreading. Union Composites designs its products to work in hot environments, up to 180°C.
The compound passes strict flame resistance tests. The table below shows how it performs:
Fire Retardancy | Limited Oxygen Index (%) |
|---|---|
2.5mm, V0 | ≥36 |
3.0mm, V0 | ≥35 |
4.0mm, V0 | ≥32 |
These results mean your equipment will not catch fire easily. The compound keeps its strength and shape, even when exposed to heat or flames. This makes it a safe choice for electrical enclosures and panels.
Chemical and Corrosion Resistance
You need materials that last, even in tough environments. Sheet moulding compound resists many chemicals and does not corrode. Union Composites engineers its products to stand up to oils, fuels, and harsh chemicals found in factories and power plants.
Application | Chemical Resistance Properties |
|---|---|
Automotive oil pans and valve covers | Good resistance to oils and fuels |
Industrial housings and enclosures | Suitable for exposure to various industrial chemicals |
Energy sector components | Engineered for chemical resistance in demanding environments |
Protective panels and covers | Designed for use in chemical environments |
The compound’s special formula prevents it from breaking down in harsh conditions. This means your electrical equipment stays strong and works longer, even outdoors or in places with lots of moisture or chemicals.
Tip: The corrosion resistance of sheet moulding compound helps your equipment last longer and keeps it working safely over time.
