Evonik PA12 VESTAMID NRG 4901 BK resin

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
