Glass cements are lead-containing glass powders that are used for soldering electrovacuum glasses, kinescopes, etc. They tend to crystallize during a certain heat treatment. Solder/sealing glass powders unlike glass cements, can be heated and cooled several times, as usual glass. PS is a composite powder that is intended for soldering electrical boards or for sealing cathodoluminescent indicators with Low Temperature Sealing (415-435C°). The warranty period is set for one year from the date of shipment of products to the consumer enterprise.

Private Enterprise "PROMSYSTEMS" produce preforms glass to metal seal of different standard sizes and shapes to order. They are used for the production: hermetics or millitary connectors with different standards (working temperature, hermetics, waterproof. etc). These are our standard based glasses with a coefficient of thermal expansions (Borosilicate, Soda-Lime, Titanium, etc): - 2.5-3.8 ppm/C; - 4.8-5.2 ppm/C; - 7.2-8.3 ppm/C; - 9.0-10.5 ppm/C; - In the production of glass preforms, we use glass of exceptional quality, in accordance with the regulatory and technical documentation for each brand; - Drawing must be attached. It is necessary to indicate with limit: 1. Outside diameter; 2. Inner diameter; 3. Height; For example: Preform (materials what you need) D1 = 3.2 +- 0.2mm, d2 = 1.4 + 0.2mm, h = 2.2 +- 0.2mm. We are reasdasdady to take on the development of new standard sizes from any glass at the expense of the customer;

The method of preparation of glass-based press powder is the intellectual property of the enterprise since its inception. For its preparation, only high-quality components are selected from those offered on the market. The glass used for the preparation of the press powder meets the requirements of ISO:9001 in terms of chemical composition and physical and chemical properties . As part of the press powder, the content of iron oxide should be no more than: for glasses G0025, G0048-50 = 0.4%; G0052-54, G0074-76 and G0091-93 = 0.55%; The minium order for one supply is from 100-150kg. When ordering, describe the technical characteristics of the glass (CTE, temprature resist), glass grade or other technical spesification. An example: Granular powder (CTE=4.9, T=-70°..+550°C) 150kg or your other characteristics. The warranty period is established for one year from the date of dispath of the product to the consumer enterprise.
