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.
PaperShell can replace wood, plastics, fiber composites and in some cases metal sheets in a number of applications in different markets.
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.
The material has a density of 1,34 gr/cm3.
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.
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.
The Tg is approximately 145°C and thus long term use at elevated temperature is possible.
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.
It can achieve many of the same designs and shapes that plastics and press moulded metal sheets can.
In Tibro, Sweden we have our R&D center and production facility where we do co-development projects and series production. In 2023 we launched our first highly automated lines and we will finalise a new bigger factory in 2024.
