For Steel Pipe Protection (Encasement)

VESTAMID® NRG 4901 black offers a flexible, mechanically tough encasement system that combines the advantages of polyethylene coating and cement mortar casing.

Uses of VESTAMID® NRG Products:
The important advantages of VESTAMID® NRG 4901 as an encasement material are:
  • unusually high impact resistance and toughness, even at low temperatures
  • excellent stress cracking resistance
  • excellent wear resistance
  • low sliding friction coefficient
Product characteristics compared with other encasement materials:
VESTAMID® NRG 4901 black has higher Shore hardness than polyethylene or polypropylene. In contrast to polyethylene or propylene encasement, therefore, the polyamide encasement offers, apart from the corrosion protection provided by the barrier effect, also mechanical protection for the encased steel pipe.

Application areas for the new encasement material are found in non-conventional installation technologies such as:
  • horizontal directional drilling
  • the soil displacement method with non-steered displacement hammers
  • dynamic ramming
  • plow technology

We recommend a processing temperature between 230°C (446°F) and 260°C (500°F) - in some cases up to 280°C (536°F) - during the extrusion process.

Drying at 80°C (176°F) for 2 hours to 4 hours before processing is recommended.
