A NEW environmentally friendly polymer coating for wire products


May 6, 2013 Officine Maccaferri Group launches PA6 – A NEW environmentally friendly polymer coating for wire products.

Maccaferri announces a new polymer coating for its steel wire products.

Maccaferri PA6 is an extruded polyamide coating for Maccaferri’s galvanised mild steel wire products. Maccaferri PA6 coated mesh has been added to the range of coatings as it offers significantly improved environmental and technical performance when compared to PVC and HDPE coated mesh products on the market.

Maccaferri PA6 is more environmentally friendly than PVC. Unlike PVC, it does not contain phthalates or ozone depleting chemicals. Also, Maccaferri PA6 does not contain heavy metals. Furthermore, it does not emit hydrogen chloride during burning, unlike PVC.

It offers improved:

Environmental performance

Resistance to mechanical damage

Cold temperature performance

Resistance to hydrocarbon pollutants

Long term strength and elasticity

Adhesion to the wire

Compared to PVC coated wire products, Maccaferri PA6 offers:

25% more elongation after 3000hrs UV test

50% harder and therefore better able to resist damage

3x better adhesion to the steel wire

30% greater design life

As it offers better performance, it is not an alternative to PVC, but an enhancement. It is to be used when PVC or HDPE coated products do not provide clients with the required environmental performance, design life or technical performance. PVC coated products are still available from Maccaferri for use in less demanding projects.

The new coating will be available globally on the full range of Maccaferri’s double twist wire mesh products including:

Gabions Reno® Mattresses

Rockfall protection mesh

Terramesh® soil reinforcement system

Green Terramesh® soil reinforcement system

It is manufactured in accordance with the official standard EN 10245-5:2011 “Steel wire and wire products – Organic coatings on steel wire – Part 5: Polyamide coated wire“.

Maccaferri PA6 has been extensively tested both on the polymer itself and on the coated wire, providing clients with a reassurance of quality and durability.
