The first rubber plant of Uzbekistan, known as “Birchini Rezinotekhnika Zavodi”** (from Uzbek - “First Rubber Plant”) became a symbol of the industrial breakthrough of the region. The founder of this enterprise set an ambitious goal: to localize the production of critical rubber products that were previously imported from abroad. Today, the plant not only supplies the domestic market, but also exports products to the CIS countries and Asia.

In this article we will examine in detail the history of the creation of the plant, its key products (from conveyor belts to hydraulic hoses), technical standards by which the enterprise operates, and we will also give practical recommendations on the selection and operation of rubber products. We will pay special attention unique vulcanization technology, which the plant adapted to the climatic conditions of Central Asia — this solution made it possible to increase the service life of products by 30% compared to analogues.

History of creation: from Soviet heritage to independence

The plant was founded in 1962 as a branch of the All-Union production association specializing in rubber products for agriculture and industry. Initially, the company produced simple parts: seals, cuffs and drive belts for tractors "Belarus" and combines "Niva". However, after the collapse of the USSR, the plant was on the verge of closure - the severance of economic ties led to a shortage of raw materials and a drop in demand.

The turning point came at 1995, when the enterprise was privatized and reorganized into JSC Birchini Rezinotekhnika Zavodi. The new owners bet on import substitution and modernization. By the 2000s, the plant mastered production GOST 20-85-compatible conveyor belts, and by the 2010s, launched a production line high pressure hydraulic hoses for mining equipment. Today the company is one of the top 3 suppliers of rubber products in Uzbekistan.

  • 📅 1962 - foundation as a Soviet enterprise.
  • 🔄 1995 — privatization and rebranding.
  • 📈 2005 — certification according to ISO 9001.
  • 🌍 2018 — start of exports to Kazakhstan and Kyrgyzstan.
⚠️ Attention: Before 2005, the plant's products may have contained asbestos fibers in sealants. When working with products older than 15 years, it is recommended to use FFP2 class respirator.

Key products of the plant: from conveyor belts to special rubber

The Birchini Rezinotekhnika Zavodi assortment includes more than 1200 titles products divided into 5 main categories. Especially in demand conveyor belts for the mining and food industries, as well as hydraulic hoses for agricultural machinery. Below is a brief overview of the key areas:

Category Product examples Standards Service life (years)
Conveyor belts General purpose tapes, oil resistant, fire resistant GOST 20-85, DIN 22102 3–7
Hydraulic hoses High pressure hoses (up to 40 MPa), spiral hoses GOST 6286-73, SAE J517 5–10
Sealing products Cuffs, seals, gaskets for pumps GOST 9833-73 2–5
Drive belts V-belts, poly-V-ribbed belts, timing belts GOST 1284.1-89 4–8
Special rubber Shock absorbers, vibration isolators, rubber coverings TU UZ 20.01-00123456-2020 5–12

Deserves special attention conveyor belts of the BRZ-T series, designed specifically for work in high temperatures (up to +80°C) and abrasive environments. Their uniqueness lies in their use two-layer rubber compound with the addition silicon carbide, which increases wear resistance by 40%. Such tapes are actively used at copper mining enterprises in Navoi MMC.

Technical standards and certification

The products of Birchini Rezinotekhnika Zavodi comply with both international (ISO, DIN, SAE), and national standards of Uzbekistan. It is important to note that since 2020 the plant has switched to a system double certification: in addition to the mandatory ones GOST, all products undergo voluntary testing according to standards TU UZ (Technical Conditions of Uzbekistan).

Particularly stringent requirements apply for high-pressure hydraulic hoses:

  • 🔬 Tensile test: the pressure must exceed the nominal pressure by 4 times (for example, for a 25 MPa hose, the test is carried out at 100 MPa).
  • 🌡️ Heat resistance: products must retain their properties at temperatures from −40°C to +120°C.
  • 🛢️ Media Compatibility: Resistant to mineral oils, fuels and glycol-based hydraulic fluids.

⚠️ Attention: Hoses certified only to GOST 6286-73 (without additional brands), it is not recommended for use in systems with operating pressures above 20 MPa. For such conditions, choose products labeled «SAE 100R2AT».

Secrets of durability: technology and raw materials

One of the main competitive advantages of the plant is use of local raw materials with the addition of imported components. For example, for production oil resistant conveyor belts brand rubber used SKI-3 (synthetic isoprene), which is mixed with nitrile butadiene rubber (NBR) from LANXESS (Germany). This combination provides:

  • 🛡️ Increased resistance to oils and solvents (2 times higher than analogues based on EDMS).
  • ⚡ Improved elasticity at low temperatures (retains flexibility down to −30°C).
  • 🔥 Fire safety (self-extinguishing properties according to GOST 12.1.044).

Another know-how of the plant - cold vulcanization technology for repair of conveyor belts. Unlike the traditional method (hot vulcanization at +140°C), a special adhesive based on polychloroprene, which hardens at room temperature. This allows repairs to be carried out directly on site without dismantling the tape.

What is “cold vulcanization”?

This is a method of joining rubber products without heating, which uses a two-component adhesive (rubber + hardener). The strength of the seam reaches 90% of the original tape, and repair time is reduced from 4–6 hours to 30–40 minutes.

How to choose factory products: expert advice

When purchasing rubber products from Birchini Rezinotekhnika Zavodi, pay attention to the following criteria:

  1. Marking: The product must indicate GOST or TU, as well as the release date (month/year). For example, "BRZ-KL 1200×6 GOST 20-85 05/24".
  2. Rubber color: High-quality products have a uniform color without streaks. A gray tint may indicate excess carbon black (reduces elasticity).
  3. Smell: A strong chemical smell indicates poor quality vulcanization or the use of recycled materials.
  4. Packing: Original products are supplied in polyethylene sleeves with the plant logo or in cardboard boxes with a hologram.

For hydraulic hoses, it is critical to check pressure marking. For example, the designation «1SN» means that the hose is designed for pressure up to 10 MPa, and «4SP» - up to 40 MPa. Also note braid color:

  • 🔴 Red - for oils and fuels.
  • 🔵 Blue - for water and air.
  • 🟢 Green — for food products (certificate FDA).

💡

Before purchasing a high pressure hose, measure internal diameter (in inches or millimeters) and compare with the equipment data sheet. An error of 1/16 inch can result in leaks or ruptures.

Operation and care: how to extend service life

Even the highest quality rubber products require proper maintenance. For conveyor belts the factory recommends:

  • 🧹 Weekly cleaning from abrasive particles (sand, ore dust) using brushes or compressed air.
  • 🛠️ Tension check every 3 months (sagging more than 2% of the length of the tape requires tightening).
  • 🌡️ Temperature control: when working in conditions above +60°C, it is necessary to use tapes with markings "T" (heat resistant).

For hydraulic hoses key rules:

  • 🔄 It is forbidden to twist hoses during installation - this leads to delamination of the braid.
  • 🚫 Avoid kinks with a radius of less than 10 hose diameters.
  • 🔧 Replacement every 5 years (even if there are no external defects) - rubber loses elasticity over time.

⚠️ Attention: When storing rubber products, avoid direct sunlight and heat sources. Optimal conditions: temperature +10…+25°C, humidity not higher than 60%. Shelf life in original packaging is up to 3 years.
💡

Regular lubrication of seals with silicone grease (for example, Molykote 111) increases their service life by 20–25%.

Development prospects and export potential

In 2023, Birchini Rezinotekhnika Zavodi announced plans to expand production capacity by 40% by 2026. Main directions of development:

  • 🏗️ Construction of a new workshop on production vibration isolation materials for the automotive industry (partnership with UzAuto Motors).
  • 🌿 Environmental initiatives: transition to rubber from guayules (an alternative to Hevea) to reduce dependence on imports.
  • 🌍 Expansion of exports to Turkey and the UAE thanks to certification for EN ISO 9001:2015.

Particular attention is paid digitalization of production. Since 2022, the plant has implemented a system MES (Manufacturing Execution System), which allows you to monitor product quality in real time. This reduced scrap by 15% and speeded up batch release by 20%.

There are also plans to launch a production line rubber coverings for sports fields (according to standard EN 1177). This project is being implemented jointly with the Ministry of Sports of Uzbekistan and should be completed by the end of 2026.
