SVECK’s POE films maintain the same listed specs as before, but include updated thickness and width options, now ranging from 400 to 800 µm and 970 to 1350 mm
The films support lamination between 143 and 153° C, with a vacuum time of 5 to 8 minutes and a press time of 12 to 15 minutes
Both models offer 18 MPa tensile strength, 90% transmittance, and adhesion strengths of 70 N/cm to glass and 50 N/cm to backsheet
Sveck, a leading EVA supplier, continues to participate in the non-EVA section of the TaiyangNews Backsheets and Encapsulation Market Survey 2024/25 with 2 POE-based products – SE-556 and SE-557. Originally introduced in 2015, both films retain their core specifications while featuring minor updates in dimensions and processing conditions over the past year. Supplied in a standard thickness of 500 µm and 985 mm width, the company is also ready to offer the product in other dimensions – 400 to 800 µm thickness and width ranging between 970 and 1,350 mm. The company recommends that the modules that use this POE encapsulation material be processed with a vacuum time of 5 to 8 minutes and a press time of 12 to 15 minutes. It supports a lamination temperature range of 143 to 153°C. All these aforesaid parameters are slightly adjusted compared to last year. The SE-556 and SE-557 are offered in a transparent form with an embossed surface finish (see Sveck's EVA Films With Varying Thermal & Mechanical Properties).
These models have a tensile strength of ≥ 18 MPa in both directions and exhibit a 70 N/cm glass adhesive strength and 50 N/cm for backsheets. The POE films have a 90% transmittance for wavelengths between 380 and 1,100 nm and water absorption of 0.05% wt. The products are rated with a refractive index of 1.48 and 1×1015 Ω cm volume resistivity.
