Learn About the Benefits of Vulcanized Fibre

Advantages include electric insulation, corrosion resistance, and reliable machinability

Vulcanized fibre is at the heart of our operations here at New Process Fibre. Since our founding in 1927, it has been and remains a significant part of our business. We utilize vulcanized fibre for our stamped components and also offer it for sale in the form of sheets, roll, and coil stock.

What exactly, however, is vulcanized fibre? This blog post will explore some of the characteristics that make it ideal for a wide range of applications.

Introduction to Vulcanized FibreVulcanized-Fibre-2

Vulcanized fibre is a kind of laminated plastic made up of one sole ingredient—natural cellulose. As one of the first ever developed plastics, it is resilient and tough. It is also very lightweight, weighing even less than aluminum, and is more durable than leather and sturdier than most thermoplastics.

The material was developed in the late 19th century by submerging 100% cotton paper in an acid bath and running it through. It was then used to spur the growth of the automotive and electrical industries, as well as significantly contributing to a variety of applications in the modern railroads, textiles manufacturing, welding, and even sporting industries.

Vulcanized fibre is typically chosen because of its high mechanical strength, exceptional strength-to-weight ratio, lightweight, and good machinability that does not splinter, rip, or crack. The material is also resistant to most solvents and chemicals like oil and grease.


Variety of Characteristics

There are five distinct grades in which you can find vulcanized fibre. These are:

  • Commercial grade—With a standard gray, red, white or black appearance, this grade is used in numerous applications like gaskets, end laminations, handles, gears, and washers.
  • Electrical grade—Historically known as “fish-paper,” this grade is dielectrically high gray appearance, composed of 100% cotton, and ideal for ground and layer insulation. This is well suited for applications which as end laminations in stators, from consumer hand tools to industrial drive motors.
  • Trunk fibre—This grade features durability, hardness, and resistance to abrasion. It is used in drum cases, surface steamer trunks, and skid and wear panels.
  • Bone fibre—This grade boasts exceptional hardness and density, making it ideal for use in tubing and tight machining, and to create products like the tips of pool cues and cut out fuses.
  • Wood laminating—This grade features toughness, high multi-directional torsion and tensile strength, and provides excellent strength and support for wood lamination applications, such as stabilizing and strengthening thin and exotic veneers.
