What can be produced? What are the limitations?

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

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.

What does the material consist of?

It consists of the same building blocks as wood. 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 a byproduct of food production.

What does the material weigh?

The material has a density of 1,34 gr/cm3.

How thick/thin can the material get?

A normal span is 1,5 to 5 mm thickness but we are capable of producing parts that are 0,5 mm and all the way up to 20 mm.

Can the material be used externally?

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

How is the material heat resistant?

The Tg is approximately 145°C and thus long term use at elevated temperature is possible.
