Arkema perovskites for solar PV encapsulation films

Home " Product Center " Repository " Arkema perovskites for solar PV encapsulation films

Solar PV panel structure, from top to bottom: frame/glass/encapsulation film/cell/encapsulation film/backsheet

Encapsulation film is generally used EVA, POE or EPE (EVA and POE composite film), encapsulation film requires good electrical insulation properties, weathering, aging resistance, can be used for 20-30 years;

Arkema peroxides are used in protective films.

Peroxide products used in Arkema's solar encapsulation films:

Improvement of PV film production efficiency, extension of scorch protection technology and significant reduction of gel risk;
It can be cured quickly at low temperature to improve the production efficiency of lamination in component factory; avoiding gel point and hard lumps in the process of heating up;
In EPE film, synchronized cross-linking of POE and EVA is possible;

model number	clarification
Luperox® TBEC-H	High purity (≥98.5%), low ionic content (e.g. CL-, NA+)
Luperox® LC	TBEC-H's patented extended coking product;
Luperox® TCS	LC's fast curing product that reduces thermoforming time;
Luperox® TP	Highly fast curing product for LC; Curing speed: TP>TCS;.

In EPE film, POE is paired with TCS for faster vulcanization speed and LC for EVA, which can achievePOESynchronized crosslinking with EVA.;

EVA film: TBEC-H or TCS or TP is recommended.

POE film: TBEC-H or TCS is recommended.

In EPE film, POE is paired with TCS for faster vulcanization speed and LC for EVA, which can achievePOESynchronized crosslinking with EVA.;

Recommended dosage:

In EVA: 0.5-0.8%

In POE: 0.65-1.1%
