INFORMATION ON THE MATERIALS USED

We trade materials from technical hardened plastics or, in popular terms, composite plastics; and we machine technical plastics, heat-resistant plastics and thermoplastics. Our products are for example electrical insulators, cable holders or slot wedges.

From the point of view of mechanical properties during heating, we process thermosets (duroplasts) as well as thermoplastics, however, the majority of production consists of machined thermosets. Thermosets are plastics which, when hardened, cannot be softened to a malleable state, even when heated more strongly. Thermoplastics soften to a ductile state when heated, solidify again when cooled, and these changes in ductility can occur repeatedly.

You can find a comprehensive overview of the main processed materials here in table of materials and on previous page MATERIALS.

Description of the most frequently machined hardened plastics:

• FIBREGLASS (TEMPERED GLASS FABRIC) AND OTHER MATERIALS BASED ON GLASS FIBRES
  Fibreglass is a layered material made of glass cloth (reinforcement) and epoxy resin (binder). In addition to good mechanical and electrical insulating properties, it also has high thermal resistance.

In addition to woven fabrics (hence the name fiberglass) there are also reinforcements such as glass roving and glass mat (Hartmatte).

The most important representatives of the materials we machine in these categories are called according to European standards EPGC 201 (EPC 201), EPGC 202 (EPC 202), EPGC 203 (EPC 203), EPGC 204 (EPC 204), EPGC 306H (EPC 306H), EPGC 308 (EPC 308) or EPGM 203 (EPM 203);

according to American NEMA standards we denote the same materials by abbreviations G10, FR4, G11, FR5

and according to German DIN standards we may refer to HGW 2372, HGW 2372.1 or HGW 2372.4 in different flammability classes.

If the laminated material is made of combination of glass fibres and (usually in the form of glass mat) and polyester resin, we call the material UPM.

The most important representatives of the this type of materials is UPM 203 (red UPM 70 or white UPM 71S), UPM S1 (UPM 72) and UPM S2 (UPM 204R and UPM 205) usually of beige or white-cream color. Abbreviations are often also referred to as UPGM 203 etc.

• HARDENED COTTON FABRIC
  Cotton fabric is a layered material made of cotton cloth (reinforcement) and phenolic resin (binder).

The most important representatives of the this type of material are called according to European standards  PFCC 201 and PFCC 202 and according to German DIN standards HGW 2082 or HGW 2082.5 and are usually of brown color.

• HARDENED LAMINATED PAPER
  Laminated hardened paper is a layered material made of cellulose paper (reinforcement) and phenol-formaldehyde resin (binder).

The most important representatives of the materials we machine in these categories are called according to European standards PFCP 201 and PFCP 202 and according to German DIN standards HP 2061 or HP 2061.5 and materials are usually of brown color. With a surface layer of melamine they can have gray color, in case of decorative boards the surface can have even many other colors.

We also trade and process HPL boards (High-pressure laminates) in this cathegory as an alternative to laminated paper with improved electrical insulation properties.

• THERMAL INSULATING SHEETS AND BOARDS

We process  ARMATHERM (Glastherm) HTLC, ARMATHERM (Glastherm) 200 HT, ARMATHERM (Glastherm) 250 HT, ARMACEM 506, ARMACEM 600, ARMYLEN, ARCLEX and few types of Sindanyo material.

• MICA SHEETS

In this cathegory, we process  ARMICANIT M (Muscovite) and ARMICANIT P (Phlogopite), these are materials on the base of mica reinforcement and silicon resin.

• THERMOPLASTICS

We also do machining of Plexiglass PMMA, polycarbonates Makrolon and Lexan, Teflon, Nylon and polyamides PA6 and PA6 G.

 
 
Our traded article portfolio also includes flexible insulation: epoxy impregnating varnish Epoxylite, Elan-Tron, Aquanel; also Mylar, Nomex.
