State-owned Enterprise “RADMA” was established on 01.04.1994 based on R&D findings developed by L.V. Pisarzhevskii Institute of Physical Chemistry of the National Academy of Sciences of Ukraine.

Core areas of activity:

— Development and implementation of innovative environmentally friendly technologies for sterilization of test and commercial lots of medical equipment and materials, for decontamination of vegetable feedstock and consumer goods.
— Development and implementation of innovative electro-physical technologies for modification of polymer materials and finished products.
— Development and implementation of technologies for recycling and regeneration of rubber waste products intended for further use in producing sealing compounds, mastic resin and reinforcing filler for roadway paving.
— Testing radiation protective properties of composite materials, radiation resistance of instruments, materials, coating and equipment to issue product certificates for applications in Nuclear Power Plants of Ukraine.

The Company can offer the following:

— Services for sterilization of a wide range of medical products and equipment (maintenance fluid and blood transfusion equipment, bandage gauze, cotton wool, medical appliances, dentist’s equipment, bone tissue, implants, materials for surgical suture, orthopedics, cardiology, disposable underwear, gynecological examination kits), bioactive additives, cosmetic and perfumery products, and animal feedstuff.

— Validation of sterilization processes for every product.

Services for decontamination of pharmaceutical drugs (lactose, fructose, amylase, maltose, bifid bacterium, antibiotics, dry apple powder) and other vegetable feedstock for pharmaceutical industry.

— Technological process for modification of polymer nanocomposite materials and products to improve performance, strength and thermal resistance; heat shrink polyethylene sleeves, films, heat shrink sleeves and films with sealing layer coating, self-extinguishing polyethylene products; items made of polyethylene, propylene, polyvinylchloride for various intended uses; semi-conductor products.

Modified polymeric sealants, main and supply pipes, sealing glands for gas transportation, compressors and machining equipment operated under heavy mechanical and thermal (up to 130 0С, and up to 2000С peak) loads. The products’ wear-resistance is 5-10 times better than that of the commercially applied industrial counterparts.

— Services for electron-beam modification of polymer films “Temp”, of couplings and locks applied for sealing and isolation of oil and gas pipes and joints.

Heat shrink film is a material composed of the base (radiation grafted polyethylene) and hot-melt adhesive substance. Good adhesive properties of the glue, strength and elasticity of the film, an extensive shrinkage (up to 50%) make these materials fit for preventing corrosion when constructing and repairing oil and gas pipes at both straight and elbow sections, and at pipe reducers. The grafted base of the film ensures high durability and resistance against mechanical ground loads. Heat shrinkage sealing gland is made based on the compound of stabilized polyethylene. In the course of installation, it shrinks to make good sealing on the surface of a pipe joint weld thus ensuring high mechanical performance in underground applications.

— Environmentally friendly zero-waste technologies for regeneration of spent rubber and rubber processing tailings (tires, diaphragms, etc.) to obtain butyl reclaimed rubber, a universal material featuring wide range of plasto-elastic, physical and mechanical properties used as recovered raw materials instead of butyl-rubber.

Reclaimed rubber is a modern highly efficient base for producing construction materials:

  • sealing and waterproof mastics;
  • rolled roofing materials;
  • waterproof films;
  • reinforcing filler for bitumen and roadway paving that improves physical and mechanical properties of asphalt concrete by 15-35% and increases the life of the paving.

Sealing butyl reclaimed material can be applied for finishing and packing of joints in integrated engineering structures, for rehabilitation of the waterproof joints in buildings and structures, for waterproof applications in industrial and civil construction.

— Radiation treatment of products made of organic, carbon and fiberglass composite materials.

Reinforced plastic materials produced with ionizing radiation processing feature better physical and mechanical properties and are more feasible than the products obtained with thermochemical hardening.

Fiber-reinforced composite materials providing protection from ionizing radiation have been developed to reduce radiation effects in nuclear industry.

Protective properties of individual products made of organic plastic and polyethylene compositions have been improved. The materials are of low weight but they ensure better shock resistance, strength, and durability under mechanical stresses.
