High-performance PTFE-based Solar Cell Membrane(TPF)
For all system voltage
BODA TPF is compounded of three layers materials,with thickness,from 200um to 350um,According to different thickness,TPF can meet the requirements of all system voltage(Max system voltage≥1200v),The solar modules who ues BODA TPF back sheet also have passed the TUV test.
Reliable Weatherability
BODA TPF is compounded of two-layer hign-quality

Excellent Scratch Resistance
The production of BODA TPF is different from traditional physical way which is compounded of multi-layer film by adhesives.It directly ueses the hign-quality

fluorine resin by cross-linkage reaction under hign temperature and then film the fluoring resin on the surface of PET.whose membance process is a kind of chemical reation after membance process.the three-layer materials will be integrate material without gaps.Though cross-linkage reaction.the molecular structure os FEVE fluorine resin is a network the scartch resistance of TPF is better than TPT material who use three-layer films compounded by adhesives.It makes solar modules are applicable to desert,wind and dusty areas,and stand severe environment without damage for long time.
Efficient Corrosion & Humidity Eesistance
BODA TPF daopts the coating strutre by fluorine material,which is acid-resistant,alkali-restant,chemicals anti-corrosion ans prevert the erosion of acid rain.Meamwhile,the sturcture of conating surface is compact,which can prevent he permeation of watervapour and other harmful gas,with the execellent corrosin & humidity resistance.Ever if in the coastal and humid areas,it also can ensure the solar modules working for long time.

Hign Reflectivty & Colors Selectvity

fluorie resin choosed by BODA TPF is with higer transparence.whose molecular structure places in alternate rules and the pigment dispersity and basic adhesivity are much better.It can be made into white TPF film,whose reflectivity is ouer 95%,at the same time,here are nanoscale multihole aerosil materials in the surface of this structure to enhance the heat dispersion of film surface,and reduce the operation temperature of solar modules to raise their conversion rates.The TPF back sheet can be made of different colors of transparence to satisfy customer different requests.

BODA TPF adopts the fluorine resin which is after stem grafting.The molecular chain of fluorine resin has been inserted by vinyl ether groups which can improve its adhesivity,so as to ensure the favorable adhesivity of back sheet with EVA,silica geletc.
Delivery Guarantee,Convenient Ues
currently,the BODA TPF production line with annual capacity of 7 million square meters has been put into operation.The product!s thickness and specification is completed.whose maximum breath is up to 2000mm and can be divded and cut into different breadth,Meanwhile,BODA can offer sliced or other personalized services accoding to customer requests.
