Polycarbonate Washers
Polycarbonate Washers (PC Washers) are precision-engineered transparent components made from high-grade Polycarbonate, a thermoplastic known for its exceptional impact resistance, dimensional stability, and thermal performance. Lightweight yet strong, PC washers provide reliable load distribution and insulation in mechanical assemblies where metal washers may be unsuitable. Polycarbonate's natural electrical insulating properties and resistance to chemical attack make these washers ideal for electronics, medical devices and sensitive equipment. Their transparent, clear design allows for visual inspection of assembly points, improving precision in installations.
What Makes Polycarbonate Washers Clear?
Polycarbonate clear washers are manufactured from high-purity transparent polycarbonate resins. The material's uniform molecular structure and low additive content result in optical clarity without sacrificing strength or durability. Unlike other plastics, PC maintains clarity even under mechanical stress, heat, or UV exposure, making it ideal for applications where visibility or visual inspection is critical.
When Would You Use PC Washers?
Polycarbonate washers are perfect for applications requiring:
- Electrical insulation – ideal for sensitive electronics and printed circuit boards (PCBs)
- Weight reduction – lightweight alternative to metal washers
- Chemical resistance – resistant to oils, fuels, and many common chemicals
- Impact resistance – can absorb shock without cracking
- Aesthetic or visibility needs – clear or transparent design for inspection points
Common applications include electronics, medical devices, laboratory equipment, automotive dashboards and custom engineering assemblies.
Why Choose Polycarbonate Washers?
PC washers combine durability, transparency, and electrical insulation, making them a versatile choice for industries where metal washers would fail. Available in a range of sizes from M3 to M16, these clear and transparent washers offer precision, reliability and excellent chemical resistance, ensuring long-lasting performance.

Frequently Asked Questions
Polycarbonate is a strong, lightweight plastic known for its high impact resistance and clarity. It is commonly used where durability and transparency are needed, such as in safety guards, protective covers, lenses and electrical components. It is also heat resistant and more impact resistant than many other plastics.
Yes, polycarbonate is very strong.
It has high impact resistance, is difficult to crack or break and is much tougher than standard plastics, which is why it is used for safety guards, protective covers and engineering components.
Polycarbonate is not easily flammable, but it can burn under high heat.
It has better fire resistance than many standard plastics and is often available in flame-retardant grades, but it is not completely fireproof.
