Vulcanized Fiber |
| Vulcanized Fiber, also known as Fish Paper or Leatheroid, is a flexible and extremely durable paperboard material used mainly for electrical insulation due to its excellent dielectric and electrical properties. Vulcanized fiber is a tough, laminated plastic made of cellulose that is available in different grades. Fishpaper is the most common grade, and it is also referred to as Standard Electrical Grade Vulcanized Fiber. Fishpaper is made in thinner gauges than vulcanized fiber, and it also has good forming and punching capabilities. All Seals can die cut and machine Fishpaper to your exact requirements. |
