Vulcanized Fibre is a laminated plastic composed of natural cellulose. Vulcanzied Flat Fibre Washers made from this material is an excellent alternative in many applications. One of the first plastics ever developed. Vulcanized Fibre is a tough, resilient material that is lighter than aluminum, tougher than leather, stiffer than most thermoplastics. Standard Colors available are Red, Black, White and Grey. Other colors are available upon request.
All Washers are available in English and Metric Units.
