Novosibirsk Institute of Organic Chemistry Siberian Branch of the Russian Academy of Sciences has developed high-performance non-toxic and nonstaining additives-modifiers of polymeric materials – СО-3, Stafen, Benzon-P, TAB, CО-4, Kalixaren – used inlight- and termostabilization of polypropylene, polyethylenes of high and low pressure, polystyrenes ABC- plastics, radiation- or peroxide cross-linked polyethylenes, epoxide, and rubbers. Unlike many applicable polymeric additives, the novel stabilizers developed in Novosibirsk Institute of Organic Chemistry possess unique combination of useful properties which makes them a new generation additives to polymers:

  • Non-toxic (belong to III-IV class GOSTof 12.1007.76)
  • Do not dye polymeric materials
  • Polyfunctional
  • Practically non-volatile, thermostable at temperatures  higher 250оС
  • In mixtures with amino- and sulfur-containing stabilizers show a synergy effect – substantial strengthening of stabilizing efficiency
  • Improves stability, bending resistance, durability, steadiness to mechanical loading of the goods from polymeric materials

The developed stabilizers are synthesized from available domestic materials in standard technological equipment.

The stabilizers CO-3, Stafen, Benzon-P are authorized by the Public Health Ministry and can be used in the goods contacting with foodstuffs and human body.

Novosibirsk Institute of Organic Chemistry pilot plant produces development batches of additives to polymers.

STABILIZER TAB 

Stabilizer TAB is an effective modifier of performance properties of technical polymers. Besides, it has a high antioxidant efficiency. It is moderately toxic and low volatile. It is very soluble in usual solvents. TAB modified polymeric goods have natural coloring which is preserved in operation. 

In composition with amine stabilizers, TAB significantly strengthens its properties.

TAB is a slightly colored adherent resin or its solution in toluene. The content of di- and polysulfides in the resin is not less than 50%.

Advantages

  • Universality: TAB – modifying  additive for a wide range of polymers with processing temperature being higher 140оС (rubbers, epoxide, polystyrenes, ABC-plastics, polyolefines, polyamides).
  • Increase of operation life of polymeric goods containing TAB and the possibility to use them in extreme conditions: under the conditions of overheating to more than 230оС, intensified load impacts and bending deformation the goods preserve their operation properties during several hours unlike industrial additives-stabilizers which tend to decay within several minutes under the similar conditions.
  • Providing essential requirements to the goods: weather- and radiation resistance.
  • TAB is one of the cheapest additives nonstaining polymer materials.  It is produced on the basis of cheap available domestic raw materials on the standard equipment.

Practical realization

Technological methodology of TAB production has been developed. Novosibirsk Institute of Organic Chemistry pilot plant produces and certifies development batches of the product. Full-scale industrial testing has been successfully completed in the production of tire rubbers, fiberglass plastics, epoxide and peroxide cross-linked compositions.

Application 

Thermostabilizer and modifier of polymeric compositions, ABC-plastics, polymers produced on the basis of epoxide,  eroxide cross-linked and radiation cross-linked compositions based on polyethylene and polyvinylacetate is used in the production of all-weather microelectronics, benzine-resistant and tire rubbers. TAB is effective in the production of fiberglass plastics and other filled compositions used in the production of domestic goods exposed to short-term extreme loads.

STABILIZER СО-3

Description

Stabilizer СО-3 is a polyfunctional additive:

  • high-performance antioxidant of organic materials (foodstuff, medication, monomers);
  • nonstaining high-performance thermostabilizer;
  • modifier of the main service properties of polystyrenes, ABC-plastics, radiation- or peroxide cross-linked polyethylenes, epoxide, significantly reinforcing their firmness and stability.

Stabilizer СО-3 is a non-toxic substance. It is authorized and certified by the Public Health Ministry of the Russian Federation and can be used in the production of foodstuff, milk and butter packaging.  It is recommended as an antioxidant in the production of foodstuffs, i.e. it can be added directly into both foodstuffs and its package (paraffinized, waxed, and laminated paper, polymer films and package). The products containing antioxidant СО-3 can be subject to heat treatment.

Stabilizer СО-3 reveals high efficiency when added to polymers used in the production of high-strength thin-walled covers, materials for electric communication cables and pipelines.

stab_co_4

STABILIZER CО-4

Description

Stabilizer СО-4 is a nonstaining and non-toxic thermostabilizer of high performance polymers. It is practically nonvolatile. It is soluble in usual solvents.

Full-scale testing has shown that СО-4 is especially efficient for polymers used in space and aircraft engineering and automobile industry.

In the process of high-temperature processing СО-4 tends to modify the properties of filled polyamides, significantly improving their application properties and specification.

СО-4 can be easily obtained from γ-propanol and available technical raw materials in standard chemical equipment at normal pressure and moderate temperatures. The obtained technical product is purified by recrystallization from organic solvents.

Specification and properties

Pilot batches of СО-4 produced in Novosibirsk Institute of Organic Chemistry pilot plant should comply with the following quality indexes:

 

stab_benzon_p

BENZON-P STABILIZER

Benzon-P is a non-volatile and non-toxic high efficiency light- and thermostabilizer for organic materials. It is soluble in common solvents.

Benzon-P is applied in production of all-weather goods from polypropylene and polyethylene of both high and low pressure. In concentration of 0,2 % the stabilizer makes it possible to preserve light resistance and  thermostability of polyethylene at the levels Irganox 1035, light resistance of  polyethylene film d=100 mkm – at the level of Tinuvin 327. On-stream, the goods preserve their natural coloring.

During operation, the product retains its natural color..

Benzon-P can be used in the polymer industry for light-stabilization of organic coatings, in medicine, pharmacy and cosmetology for light-stabilization of organic materials.


BENZON-P is authotised by the Public Health Ministry of the Russian Federation and can be used in the production of polymers which contact with human body and foodstuffs.
