Pressmaterials: glass fiber filled pressmaterial (DSV) and granulated glass fiber filled pressmaterial (GSP) are
manufactured of glass filament yarns impregnated with polymeric phenol-formaldehyde binder.
DSV and GSP materials are designed for manufacturing of structural and electrical parts by direct and injection
molding. Products made of these materials are suitable for operation at temperatures from -196°C to +200°C
and in tropical climates.
Depending on the number of ends and the nominal total linear density (tex) of yarns, there are several
types of pressmaterials:
Depending on the length of granules, these materials have the following identification:
L - nominal length of granules 6 mm;
О - nominal length of granules 10 mm;
P - nominal length of the granules 18 mm or 20 mm.
Unlike DSV pressmaterials, GSP materials have higher bulk weight.
Advantages: high mechanical and electric-insulation properties, sufficient heat resistance and resistance to many chemically aggressive environments, good rheological properties and being well-dosed provide wide range of application DSV and GSP materials.
Application: products of DSV and GSP materials are widely used in radio engineering, electrical engineering, aircraft industry, machine building, instrument-making, and chemical branches of industry.
AG-4 pressmaterials are manufactured on the base glass filament yarns impregnated with modified phenol-formaldehyde binder.
AG-4 pressmaterials are designed for manufacturing of structural and electrical parts by direct and injection molding
as well as winding followed by curing thereof.
The products made of these materials are suitable for operation at temperatures from -196°C to +200°C and in
These pressmaterials are produced as a web material:
AG-4S - on the basis of twisted glass filament yarn
AG-4NS - on the basis of glass filament yarn
Pressmaterial AG-4V-10-4,5 is manufactured under TU U 20.1-36221647-006:2013 by co-extrusion of phenol-formaldehyde resin, glass-filler and, modifying additives.
This material is available in the form of a powder, granules of irregular cylindrical shape and their mixture. The length of the granules is from 2 mm to 5 mm. The cross-section of granules is from 5 mm to 10 mm.
AG-4V-10-4,5 is designed for manufacturing (by direct and injection molding) parts of engineering and electrical application, suitable for operation in the temperature range from -196°С to +200°С and in tropical climates.
Physical and mechanical properties of pressmaterial AG-4V-10-4,5:
Advantages: volumetric and automatic dosing can be applied when processing AG-4V-10-4,5 into ready products
Application: products made of these pressmaterials are used in radio engineering, electrical engineering, machine building, instrument-making, and chemical branches of industry.
