Technical Data – Key Points – CFC Sizes

CFC Composites for Renewable energy sectors and electronic production are ideal for manufacturers who are looking for a more advanced alternative to traditional materials typically used. Graphites are commonly used in these areas. But they bulky, heavy and fragile. These can contribute to risk of downtime due to failure and reduce output due to the sizes required. Switching to Neftec CFC Composites can aid the increase in productivity, reduce downtime, while reducing their overall costs. Neftec has a long standing history in supporting the renewables sector. Especially in Photovoltaic industry for over a decade with their CFC Composites .

Our CFC rods, Heat-Shields and Heater-plates offer exceptional durability, life-span and quality for Polysilicon production. CFC Composites For RenewableNeftec also supplies parts for many other applications, this includes Crucible reinforcement parts, heat-shielding, molten silicon sealing components, along with our standard parts that include bolts and nuts, all these aid the production of Silicon Ingot production.

The manufacture of Solar cells have several stages of production that require highly technical materials to cope with the rigours of these manufacturing environments. C/C has always been a material that has been able to cope with these environments. Our CFC Composites for solar is not only extremely light, but it offers high strength, superior longevity, cost reductions.

Today you will find Neftec CFC Composites For Renewable energies are widely used in the production of silicon monocrystals and we offer a list of applications suited for silicon monocrystal production. These include; susceptors for CVD equipment and CFC Boats and carrier plates, these trays are light and well suited for the PECVD process during Solar Cell production.
