Properties:
CMC is white and flowing fine powder. It is tasteless, smell less, mould-proof, non-toxic, non-flammable and easily dissolved in water to become transparent viscose solution.
It has the following characteristics:
- Excellent water retention even at low concentration.
- Excellent thickening effect.
- Good resistance to salt and temperature change.
- Imparts excellent rheological property.
Applications:
Oil drilling grade CMC used in fracturing fluid, drilling fluid and well cementing fluid as fluid loss controller and tackifier. It can protect the shaft wall and prevent mud loss thus enhance recovery efficiency.
Packing:
25kgs in multiply paper bags or fiber drums, 17MT/20’FCL,
or as per customer requirement;
Minimum Order: 1*20*FCL
Delivery Lead Time: 2 week(s)
Supply Ability: 1000MT per month
