PAC-R (Polyanionic Cellulose)
This product has been discontinued and removed from our shelves.
PAC-R is a kind of medium-viscosity polyanionic cellulose with medium molecular weight, and it is a high-purity product.
Function
This oilfield chemical is able to increase viscosity and reduce API filtration rate of water-based drilling fluids, and it is particularly suitable for low-solid mud where high penetration rate is needed. Moreover, this viscosifier is a cost-effective product, because it works at a low dosage rate.
| Appearance | Off-white granular powder |
| Specific gravity | 1.5-1.7 |
| Solubility in water at 20°C | Dispersible |
| Purity (% by weight) | 95.0 Min. |
| Filtration (3.15 ppb) | ≤10 |
| Viscometer reading at 600rpm for 30min | In DI water (2.7ppb): 59 |
| In 40g/dm3 saltwater (2.7ppb): 53 | |
| In saturated saltwater (2.5 ppb): 57 |
Safety and Handling
For safety considerations, personal protective equipment is highly recommended and actually it is a must. Before work, please refer to the precautions illustrated in the MSDS.
Packaging and Storage
PAC-R is packed in 25kg (50lb) paper sacks.
The container should be closed, and then placed at a dry, well-ventilated area that is away from heat, sparks, flames and incompatible materials. For palletizing, banding, shrink-wrapping and stacking operations, please follow safe warehousing practices.
