ap extrusion systems for the extrusion of natural fibres

Productphoto NFPower

It is our responsibility to protect the future of our children. This was the main aspect to develop natural fibre products. Since a couple of years we have filed German, European and PCT patents.
Natural fibres are wood fibres, soft- and hardwood, rice and coconut shells, straw and all other organic natural fibres. Those fibres are hydrophilic. That means wood that derives directly from the wood has a moisture content from twelve to 18 percent, sawdust from the furniture industry has a moisture content from six to eight percent. Humidity is always to the disadvantage of the extrusion of plastic material. That means that natural fibres have always to be dried or the humidity has to be expensively compensated with chemical means. Only when the natural fibre is completely dry it is possible to reach a good adhesion between the plastics and the natural fibres as well as an enduring strength.

Additionally, it is important that the natural fibre particles are uniformly distributed and homogeneously mixed with the plastic matrix. Are those requests accomplished the final product will be of a high quality, high strength and will have a good water resistance (e.g. after storage in water).

This is an economical way of the extrusion of natural fibres.

Natural fibres can be employed in composition with rigid and non-rigid PVC recipes, with ABS, SAN, polystyrene derivatives, LDPE, HDPE, polypropylenes, co-polymers, PC or a large variety of other thermoplastics.

The ap extrusion company has developed three individual processing techniques for natural fibres.


» NFPower 26-1 and NFPower 33-2

The ap extrusion company offers the NFPower 26-1 and 33-2 in three sizes:

• NFPower 75-26-1 and NFPower 75-33-2 for an output from 100 to 200 kg/h
• NFPower 94-26-1 and NFPower 94-33-2 for an output from 200 to 400 kg/h
• NFPower 115-26-1 and NFPower 115-33-2 for an output from 350 to 600 kg/h

» NFPower 40-6 - ap extrusion standard

Due to the issue of predrying the ap extrusion company has developed the NFPower 40-6. Several world-wide patents were filed for it. That system works without predrying. The barrel has a L/D ratio of 40 with six degasifications. Two of those degasifications are connected with a special vacuum pump. The other four degasifications are connected with special humidity pumps. Those four degasifications are constructed on special cyclone burner and a particular filter system. The NFPower 40-6 can process wood fibre with a moisture content from six to eight percent with predrying it.
The advantage of this system is that with low energy costs natural fibre products of a very high quality can be produced. It is possible to use that system with plastics combined with natural fibres and additives that are constantly mixed by a Crammer feeder developed by ap extrusion company. Thus, a large variety of plastics and fibre qualities as well as a multitude of different percentages can be processed.

The ap extrusion company offers the NFPower 40 in four sizes:

ap extrusion offers experience to all customers
ap extrusion customers have advantages thanks to patented high-technology
ap extrusion offers workshops and training about wood fibre and natural fibre knowledge
ap extrusion offers attempts and test runs with our customers' recipes and their improvement
