Thermoset replacement in electrical equipment is a compatible process with lower environmental impact than thermoplastics, but it requires attention to design specifications.
In the case of this circuit breaker, a reinforced PBT with a halogen-free formulation was successfully used thanks to the UL94-V0 certified self-extinguishing at 1.5 mm and a CTI value of 600 V.
ELECTRONICS FOR SOLAR SYSTEMS
Electronic devices used in the solar field have very strict requirements in terms of flame resistance and performance over time.
The chosen compound offers maximum performance in terms of flame resistance and a UL-certified Relative Thermal Index at 140°C.
Excellent levels of self-extinguishing and resistance to creeping currents, but also good fluidity to uniformly fill thin walls without causing deformation.
The manufacture of housings for industrial condensers also requires the use of robust and resilient materials, such as LATAMID 6 H-V0.
COVER FOR RECESSED LAMP
The housing of lighting elements involves a discontinuity in the thermal insulation of ceilings unless the lamp is housed in a dimensionally very stable and thermally insulating container, which has also to be self-extinguishing and resistant to GWIT and GWFI tests.
Self-extinguishing and structural uses are normally not available in a single material due to formulation constraints.
This is not the case of LATAMID 66 H2 G/50-V0HF1 in which the UL94-V0 certified flame resistance is ensured by a matrix containing 50% glass fiber by weight.
A proposal without halogens and red phosphorus, ideal for metal and thermoset replacement.
ENCLOSURE FOR ELECTRONICS, RAILWAY SECTOR
Intended for use in the railway sector, this ABB contact carrier requires maximum self-extinguishing properties as well as resistance to 600 V creeping currents.
R22 HL3 requirements according to the European standard EN45545 are met by the low toxicity and opacity of LATAMID 66 H2 G/25-V0CT fumes.
SUPPORT FOR ARMORED RESISTANCE
To support armored resistances used in the household appliance sector, a self-extinguishing material is required, which should also feature dimensional stability to facilitate assembly, as well as chemical and temperature resistance.
The classic formula of reinforced compounds filled with red phosphorus of the KB family perfectly meets these requirements.
A typical application is that of fuse holders, in which, however, excellent self-extinguishing properties are to be combined with flexibility, temperature resistance and good aesthetics.
In addition to all this, LATAMID 68 H2-V0 also offers a Temperature Index of 130°C.
