Elastomer Powder
FC-E401S elastic powder is a dry powder cement additive for oil well cementing jobs. This material will not negatively alter key properties of cement slurry, including thickening time, slurry rheological behavior and free water separation. It matches most conventional cement formulas, and only supports dry blending during cement batch preparation, wet mixing operation is not allowed.

Usage & Application
Suggested addition dosage: less than 4.0% BWOC (by weight of cement). Applied primarily to oil well cement sheath modification, lowers cement brittleness and improves the elasticity of set cement stone.
Package & Storage
Standard packing: 25kg woven bag, customized packaging available upon request. Valid shelf life reaches 24 months under proper sealed storage conditions.
