WIRES FOR PAPER MILLS AND THE PAPER AND CARD CONVERTING INDUSTRY

The paper and paper and card converting industries work primarily with cellulose-based materials.
These factories may be classified into different categories according to the type of product they make.

The range of finished products coming out of a paper mill, representing the raw material going into a paper and card converting industry, includes semi-products composed of one or more layers of cellulose, which may have different forms and be joined with adhesives.

Most of these adhesives contain casein, a high quality protein of animal origin. Unfortunately, this substance has a negative effect on PVC wires, quickly making them rigid so that they break easily. The phenomenon is most evident in mobile application, as dynamic stress speeds up the process.

In machines that work with cardboard and generate dust, such as a cutting system, for example, or any other machine located in this type of environment, PVC wires must be protected from contact with dust.
If physical protection is impossible due to the mechanics of the machine, as in the case of wires for mobile application to cable-bearing chains, it is advisable to use polyurethane wires from the PMXX family.
