This board is a rigid, dense multi-ply material constructed from unbleached kraft pulp and acrylic polymer. It has the UL-94 Flammability Classification of 94HB.

It is rated for a working temperature up to 230°F (110°C).

VHR 115 has excellent dielectric (250 volts / mil) and mechanical strength, low water absorption, high punch-ability and fold-ability.

This material is recommended especially for applications requiring fold lines and creases in material thickness greater than 0.020 in. (0.50mm). VHR-115 will not break when folded, unlike fish paper.

VHR 115 is an industry accepted substitute for fish paper, particularly in the thicker material range.

VHR 115 vs. Fish Paper

If you work in the electronics industry or another sector where you use electronics in your applications, you are probably familiar with fish paper. Fish paper is very popular as a material for insulating electrical devices because it has an electrical insulation Class 110 degrees Celsius mechanical rating and a Class 115 degrees Celsius electrical rating.

Typically, if you need a protective coating that is heat-resistant and electric tracking-resistant, you would die cut fish paper to fit your component as a more reliable alternative to unconverted cellulose.

However, in some cases, fish paper may be too thin to stand up to the stressors your application will put it through. In these situations, VHR 115 — a more rigid, dense material made from kraft pulp and acrylic polymer — is a clear alternative. Just like fish paper, VHR 115 is approved by Underwriters Laboratories reference E-31556(M) at 110°C mechanical and 115°C electrical. It does not break when folded, has high mechanical strength and dielectric strength, can be easily punched and has a UL-94 Flammability classification 94HB.

VHR 115 also has no chemical impurities, conducting particles or foreign matter that could interfere with the components you apply it to. When your fish paper is not doing the job, it’s a great idea to have VHR 115 available as a substitute.

We are the die cutting experts, and are also proud to provide custom laser cut VHR 115 components.
