Which materials can I replace with PaperShell?

PaperShell can replace wood, plastics, fiber composites and in some cases metal sheets in a number of applications in different markets. The highest environmental and cost effect is to replace aluminium and fiber composites like glasfiber.

For which products can the material be used?

The range of products that the material can be used for is wide as pressing can be done in a wide thickness and 3D-geometry span. Parts can thus be both aesthetic and/or load bearing.

What does the material consist of?

It consists of the same building blocks as wood or plants: Cellulose, hemicellulose (derivative), and in some cases lignin. The source is from the forest, and we collaborate with local or Swedish producers who restore cultivated forests to deciduous or natural forests. Currently, hemicellulose comes from by-products from agriculture without competing with food production.

What can be produced? What are the limitations? Size, thickness, shape.

PaperShell is mainly based on compression molding meaning that you can achieve basically the same geometries as pressed sheet metal but also complex geometries achieved with fiber composites and certain injection molding geometries.

What are the capabilities of this material in terms of design and shape?

It can achieve many of the same designs and shapes that plastics and press moulded metal sheets can.

What does the material weigh?

The material has a density of 1,34 gr/cm3 but is stronger than wood and plastics having a good strength-to-weight ratio meaning less need for material. A rule of thumb is 2 mm thick component in PaperShell has the same weight and strength as a component of 1 mm aluminium but the PaperShell component will have… Continue reading What does the material weigh?

How thick/think can the material get?

Our normal span is 1,5 to 5 mm thick but we can produce parts that are 0,5 mm and all the way up to 20 mm.

What colours can you get the material in? Can it be surface-treated?

The natural colour of PaperShell is light brown to almost black with a carbon colour look. It is of course possible to paint or foil PaperShell in any preferred colour but then you lose the highly valued PaperShell appearance. It’s also possible to dye the paper before pressing in darker shades of blue, red &… Continue reading What colours can you get the material in? Can it be surface-treated?

Can the material be used externally?

Yes – we have conducted extensive testing to evaluate performance in an outdoor environment. There is a natural wood-like ageing of the surface of the material while the mechanical performance is kept at its high original level.

How does the appearance of the material change over time?

Indoor it stays the same. Outdoor, without any surface treatment, it turns silver grey like wood in 3-6 months, but without the performance loss found in wood.
