Aramid packing impregnated PTFE type EAP/ST
This packing is braided of premium aramid yarn of stack (cut) fibres and impregnated with PTFE dispersion.
As a result, the rope is resistant to both mechanical and chemical factors.
Application
EAP/ST packing is a high-quality packing for high-pressure pumps and fittings used in all industry branches. Particularly recommended in contact with strongly abrasive materials such as suspension of sands, sewage and other materials with abrasive impact on packings. Owing to high resistance to utilities such as water, oils, fuel, acids and alkali, it is particularly broadly applied in chemical and petrochemical industry, the power sector and the mining industry.
