ALCUDIA CN-122 Repsol YPF Polyethylene, Low Density

Product Description

ALCUDIA® CN-122 is a black compound specially designed for low voltage power cable.
ALCUDIA® CN-122 is a high molecular weight, low density polyethylene black compound which offers easy processing combined with good mechanical properties.
The molecular characteristics of ALCUDIA® CN-122 and the nature of specific antioxidant makes this material ideal for the Monosil crosslinking process.
The combination of the antioxidant system and minimun of 2.2% well dispersed carbon black used in CN-122 provides the following features: excellent protection against thermal oxidation during processing, long term stability, and excellent protection against outdoor weathering.
ALCUDIA® compound CN-122 has also been developed for extrusion of pipe of pressure water to comply with the requirements of the UNE 53-131 as a PE 32 and prEN 12201 european standard specification as a PE 40.
Based on the new ISO classification the ALCUDIA® CN-122 compound is classified PE 40.
CN-122 is a high viscosity high molecular weight low density polyethylene black compound which offers easy processing combined with a good resistance to internal pressure.
The ALCUDIA® CN-122 may be used in contact with foodstuffs. It also meets the special requirements for the supply of potable water in Germany.
