Polyproplyene (PP)

Carbon Holdings has licensed UNIPOL® Polypropylene gas-phase process technology from W.R. Grace for its OPC facility in Egypt to manufacture polypropylene. This technology, known for its stability, predictability, and minimal equipment requirements, benefits from a simple and reliable design. When combined with SHAC® Catalyst Systems and CONSISTA® Donor Technology from Dow, it allows the plant to operate above its nameplate capacity, offering significant economic advantages. UNIPOL® Polypropylene Technology's simplicity results in lower capital and operating costs, increased reliability, and reduced maintenance expenses, making it the least complex and most efficient process for polypropylene production.

Polypropylene’s strong element is its versatility for molded, extruded, and film products. Polypropylene is tailored to most plastic applications.

Features

  • Light Weight: Polypropylene is the lightest of all thermoplastics. This feature adds economical value to all applications.
  • Heat Resistant: Polypropylene has a high melting point of 168 °C. This superior heat resistance makes it useful in autoclave containers and in molded parts of automotive applications.
  • Chemical Resistant: Polypropylene exhibits excellent resistance to the direct attack of detergents, inorganic chemicals, low boiling hydrocarbons and alcohols.
  • Superior Clarity: Polypropylene has the highest “see-through” clarity of all polyolefin, and is recommended in thin-walled molding, and in both oriented and non-oriented films.
  • Stress Cracking Resistance: Polypropylene has excellent (ESCR) environmental stress crack even when exposed to soap, wetting agents and alcohols.

Products

OPC produces homopolymer polypropylene in four main categories: Raffia, Film, Injection, and Fiber.

  • Raffia: Woven bags, Ropes, Cable insulation, Carpet Backing, Geotextiles, and Tape
  • Film: Industrial packaging (metallic, plain & pearlized), Food packaging (confectioners & crackers), Green houses and tunnel plantation films, Bakery and poster wrapping
  • Injection: Injection and blow molding containers, Furnishing articles, garden furniture, table tops, etc., In-house potable and sewer water pipes - Automotive applications, and House cleaning articles
  • Fiber: Carpet facing and backing, BCF for carpet face, CF for cable fibers and wall-to-wall carpets, and Spun bonded for non-woven textile (hygiene, diapers, & agricultural applications)

Low Density Ammonia Nitrate (LDAN)

EHC’s LDAN is designed to be used as a solid oxidizer ingredient for explosive compositions for the ANFO and heavy ANFO production as the most cost-effective for dry surface and underground blasting applications.

Due to its high porosity and low density, EHC LDAN ensures high fuel oil absorption increasing the ANFO’s blasting performance.

EHC LDAN can be used for mining, quarrying, and civil construction applications.

Benefits

  • Fast and homogeneous absorber of fuel oil .during ANFO production.
  • A %100 free flowing product allowing for easier handling.
  • Highest velocity of detonation and increased release of energy during detonation.

Storage and Handling

The EHC LDAN packing conditions added to its crushing strength and low moisture retention mean EHC LDAN can stored for longer periods without any reduction in product quality.

Packaging

EHC LDAN is available in 25 kg polyethylene bags, also in 1000 kg, 1100 kg or 1200 kg polypropylene jumbo bags which are protected by an inner polyethylene liner.

Nitric Acid (NA)

EHC Nitric Acid is a colorless liquid produced using dual pressure process by oxidizing ammonia into NOx gases over platinum knitted catalyst gauzes. The NOx gases pass through a series of coolers which is followed by the absorption process to produce 60% w/w concentration. The Nitric Acid then passes through a final bleaching stage to remove any remaining non-condensed NOx gases.

Nitric Acid is predominantly used in agriculture or the production of Ammonium Nitrate fertilizer. Other applications of Nitric Acid include:

  • Nitration of organics in synthesis of dyes and polymers for the production in plastics, surface coatings, pesticides and the manufacturing .of other inorganic compounds (Adipic Acid, Isocyanates, Nitrotoluene, Nitrobenzenes, and Nitrocellulose).
  • Etchant and cleaning agent, pickling stainless steel or cleaning silicon wafers in electronics.
  • Doping agent for organic semiconductors, and in purification processes for raw carbon nanotubes.

Storage and Handling

EHC’s high purity commercial grade Nitric Acid is sold either in one-way acid-resistant composite containers or in stainless steel tanker trucks.

EHC Nitric Acid is available in:

  • 30 Litre jerry cans.
  • 220 Litre drums.
  • 30,000 - 34,000 Litre stainless steel tanker trucks.
  • 1,000 Litre intermediate bulk containers (IBC).
