Dear Sir/Madam,
We are Russian local oilfield manufacturing company and looking for purchasing of encapsulated destructor (dry product) based on ammonium persulfate with delayed activation.
We need products for with applications on 3 different temperature ranges:
1. The product is used as a destructive agent in hydraulic fracturing fluids at temperatures from 40 to 70 ° C (LT Encapsulated Breaker)
2. The product is used as a destructive agent in hydraulic fracturing fluids at middle temperatures (MT Encapsulated Breaker).
3. The product is used as a destructive agent in hydraulic fracturing fluids at temperatures from 65 to 110 ° C (HT Encapsulated Breaker).
The main advantages of above products are: Delayed destruction time due to encapsulation of the main product, the possibility of using high concentrations of the product without reducing the viscosity of the hydraulic fracturing fluid during injection of prop ant.

Would you send us please technical documents with full description and possibilities to arrange sample of 1 kg for each product to be shipped to our laboratory in St. Petersburg in Russia.
Also, price for per kg is required on FOB base, please. Packing: 50 lb pails, 1200 lbs per pallet (5 bags X 10 lbs in each pail).

Thanks in advance,
