RUBBER PRODUCTS

 

We are acting as a trader of a company , which  basic activity is the production of details of elastomers for different branches of industry /electrotechnique, shipbuilding, shiprepair, food and beverage and so on/. There is a large complex of press-formings both for standard / rings for pin connectors, couplings Stortz and other couplings / as well as non-standard products / vibrated pads, rubber gaskets for hatches and so on /. Design, construction and producing of press-formings by, by an existing detail or in accordance with the working parameters and the application specificity.
he products comply with the requirements of the Bulgarian Governmental Standard or with the technical requirements presented by a certain customer which is attested by a quality certificate. The quantity of products is agreed as it is possible to be from 2-3 units up to several thousand pieces. 

 

PRODUCTION

The process of production is carried out by press-formings and extrusion /pulling out/ for profiles. The materials used are in accordance with clients' preferences in the range of artificial and natural elastomers /rubber/, industrial silicones and silicone-based mixtures for the food-and-beverage industry. 

The tools and instruments are designed as per clients' specification, an existing detail, the application and the working parameters of a product or a drawing, sketch and/or scheme of the final product. The press-formings /matrices/ are made by the method of cold work of metal carried out by our contractual partners. There is a possibility for production by a client's tools and instruments.

We present to you a part of our possible production. 

Couplings

Couplings for low and high revolutions machines for hydraulic /water and oil/ and pneumatic /gas/ pumps. Hardness and elasticity - as per the specification of the Bulgarian State Standards or as per clients' preferences. Maximum outer diameter of a coupling - up to 650 mm. 

Electricity isolating gaskets

Gaskets for the domestic electrical system /transformators/. Over 100 sizes for high and low voltage terminals, level gauges, oil circuit-breakers, gaskets for closing of transformer reservoirs /profiles: circular, rectangular / and a possibility for producing new configurations as per the sizes of the client's order. 

Electricity resistance. Oil resistance. Shore hardness from 50 A to 75.
Certified by an accredited Bulgarian laboratory guaranteeing the quality of products.

 

Electricity isolating components 

 

Components of phenol-formaldehyde resin /phenolic plastic/ for electrical  conductance systems. Design and production according to the client's needs. Colours possible by choice.

 

Gaskets for pressure 

 

Gaskets for hydraulic and pneumatic systems. Design and production of specific, non-standard gaskets. Depending on the working environment oil-resistant, acid-resistant and atmospherically resistant ones are offered. Temperature resistant silicone-based mixtures up to 500 . Temperature resistant of synthetic rubber up to 90

Profiles and sheets

Square, rectangular, circular and profiles with geometrically irregular form. EPDM, oil-resistant, atmospherically resistant and acid-resistant ones. For dense profiles - hardness up to 80 . Micro porous profiles - hardness up to 30 . Rubber sheets, vulcanized or raw, sizes up to 600 800 x 30 mm.

 

Rubber products with metal inserts 

 

Products made of different types of rubber with inserted metal profiles are offered /rubberizing, coating/. The possibilities for production are up to 600 mm outer diameter and highness of the rubber surface up to 400 mm. The connection between the metal and the rubber is by different types of technical glues - hot or cold.
