FOREIGN ECONOMIC ACTIVITY

About us

Intersphere began in April 1995. Since our successful beginning the firm has built up, gained solid experience and established good business relationships with other enterprises in the regions of Moscow, Ulyanov, Orenburg and Perm. Agreements have been signed with several of these, which is a testament to the unblemished reputation of our firm.

Intersphere offers specific building materials (fire, heat and water resistant) and the production of chemical industry for both use on the domestic Russian market and for export.

We hope that you find the information about available materials interesting and look forward to doing business with you. In Intersphere you are guaranteed a reliable supplier and business partner.

NEW: Now we act as the agent of “GAZPROM” company. This company can possibilities to supply petroleum and petrochemical products.

LIGHT- WEIGHT AND ULTRA

LIGHT- WEIGHT PRODUCTS

SHL- 1,1 TA (technical agreement)
SHL- 1,3 GOST 5040-96
MKRL- 0,8 TA (technical agreement)

Typical Applications

• Light-weight and high insulating properties make possible to thin down wall thickness, decreasing heat accumulation, lowering power expenditures and increasing productivity of heating aggregates.
• Low heat conductivity affords to save fuel in cyclically operated heating equipment.

Advantages :

• The large number of product dimensions and shapes, carryng out shapes by customer drawings makes lining free of expenses on additional prodyct treatment and decreasing the number of joints in brick-work.
• Light-weight products (SHL-0,4; 1,1; 1,3) are used as refractories and constructive materials for hot-face or second-face heat i nsulating lining aggregates.
