- What are the main characteristics of FIBROLON®?
FIBROLON® has a high mechanical resistance and stiffness with low density. It can be processed using different processing methods, for example injection moulding, profile extrusion and deep injection. Whereas the F series is exclusively composed from biodegradable materials, the P series contains a conventional polypropylene as matrix.
- What are the preferred applications for FIBROLON®?
FIBROLON® is recommended for the injection moulding of complex components, but also for the extrusion of profiles, plates and hollow sections. These polymers are also suitable for components such as automotive interiors, stationery, coffins and funeral urns.
- Is FIBROLON® F certified as compostable according to EN 13432?
No, to date this certification has not been requested by any customer. The acknowledgement of the combination of biodegradable components and European soft wood has been adequate to date.
- Does FIBROLON® contain harmful components?
No! FKuR places FIBROLON® on the market in conformity with the relevant laws, e.g. Council Directive 67/548/EEC.
- What equipment is necessary for the processing of FIBROLON®?
FIBROLON® can be processed on conventional injection moulding machinery. However, the use of hot runners is not recommended as bioplastics tend to degrade with extended residence times or high temperatures. - What is the processing temperature of FIBROLON®?
FIBROLON® compounds have a processing temperature of about 170 °C (melt temperature). Due to the risk of a thermal decomposition of the wood fibre, melt temperatures above 200 °C should be avoided.
- What are the storage conditions for FIBROLON® in original packaging?
FIBROLON® should be stored dry, frost free and below 30 °C.
- Is it necessary to dry FIBROLON® before processing?
It is possible to process the material directly if the residual moisture content is below 0.8 %. Depending on the storage conditions, it may be necessary to test the residual moisture and dry the material at 60 °C for 4 – 6 hours (for Fibrolon P the drying temperature can be 80 °C). A high drying temperature or long drying time might result in degradation of the material.
- What is the recommended waste management for FIBROLON® residues?
Following the local regulations, FIBROLON® can be disposed of by incineration or landfill.
- Are the wood fibres used for the production of FIBROLON® coming from sustainable forestry?
Yes. Our supplier is certified in a way that his wood products comply with the requirements of the chain of custody of the PEFC (Programme for the Endorsement of Forest Certification Schemes).
