Debunking Five Popular Myths About PC Insulators

Polycarbonate (PC) insulation sheets are widely used in electrical, automotive, and industrial applications due to their excellent dielectric strength, thermal stability, and mechanical durability. However, despite their popularity, there are several misconceptions about their proper use, performance, and limitations. Misunderstanding these factors can lead to improper selection, installation failures, or even safety hazards.Let's check them together!

Is PC scratch-proof and not require careful handling?

PC is softer than glass and can scratch easily if mishandled during cutting, cleaning, or installation. Scratches can compromise aesthetics and, in some cases, structural integrity.

Solution: Use protective films during handling, clean with non-abrasive cloths, and avoid sharp tools during fabrication.

Is PC always flame-retardant?

While many PC sheets are available with flame-retardant (FR) additives, not all are inherently fire-resistant. Common PC can melt and drip when exposed to open flames.

Solution: For applications requiring fire safety, always specify flame-retardant (UL94 V-0 or V-2 rated) PC insulation sheets.

Does PC attack by chemical solvents?

PC can be attacked by strong acids, alkalis, and certain solvents (e.g., acetone, ammonia), leading to cracking or loss of insulation properties.

Solution: Verify chemical resistance before using PC sheets in environments with exposure to harsh chemicals. Alternative materials like PTFE or PEEK may be better suited for aggressive chemical conditions.

Can PC maintain the same dielectric strength in humid conditions?

Moisture absorption can slightly reduce the dielectric performance of PC sheets, especially in high-humidity environments. While PC is less hygroscopic than some other plastics, prolonged exposure to moisture can still affect insulation efficiency.

Solution: In humid or wet conditions, ensure proper sealing or use moisture-resistant variants. Regular inspections are recommended.

Can PC be attacked by UV degradation in outdoor applications ?

Standard PC sheets can yellow and weaken when exposed to prolonged sunlight due to UV degradation. This reduces their mechanical and insulating properties over time.

Solution: For outdoor use, opt for UV-stabilized PC sheets or apply protective coatings to extend their lifespan.
