Santoprene TPV for solar applications
Time of issue:2021-10-22
Santoprene TPV is a material that combines the easy processing properties of thermoplastic with the durability of thermoset rubber, and has been commercially available for thirty years. It is used in a wide variety of industries, including automotive, construction, home appliances, sanitary ware, and power tools. With the booming of the solar industry, its excellent performance has been successfully applied in this industry as well.
Typical successful applications in solar energy are: photovoltaic connectors and solar street light seals.
As we all know: the photovoltaic industry for the connector material requirements are very demanding: 1: weather resistance - the requirements of the resistance to weathering.
1: weather resistance - require good ozone resistance or even reach f1 outdoor use grade
2: flame retardant - required to achieve V-1 grade or higher 5VA grade
3: Temperature resistance - -40 ℃ to 80 ℃ cycle test
4: Environmental protection - in line with ROHS and REACH regulations; recyclable
5: Flexibility - requires good resilience and excellent sealing performance
6: low temperature - in minus 40 ℃ to maintain good flexural and impact resistance
7: Voltage resistance - can withstand certain voltage breakdown, excellent insulation performance
For this particular application of PV, ExxonMobil recommends two material-specific specifications: black: 151-70W256 and natural: 251-80W232, which have been used successfully.
