Company scope
What the company makes
CGN Juner New Materials (中广核俊尔新材料有限公司) sells engineered materials under the Juner name. For module makers, the item that matters is its electron-beam-cured lightweight PV backsheet, which sits in Juner's own solution list on the CGN Nuclear Technology website. The same member-company page gives a Wenzhou address, a named business contact and a company history that starts in 1995, with a group restructuring in 2017.
Most of Juner's catalogue serves other markets: modified polymers, honeycomb panels and battery-protection composites for vehicles. The strength and fire-exposure figures quoted for the battery composite belong to that product. For a backsheet quote, ask for the backsheet's own data.
Two outside publications fill in the picture. A September 2026 composites exhibition report shows Juner presenting an EB-coated lightweight flexible PV backsheet. A 2025 journal paper on continuous-glass-fibre/polypropylene (CGF/PP) support sheets lists Juner's Zhejiang subsidiary among the author affiliations. That paper studies uncoated sheets under accelerated wet heat, so its results describe a support layer. Neither publication gives a grade number or a finished-module test.
A good first enquiry names the full construction you want quoted: support layer, coating, barrier layers and the surface that bonds in your laminator. Ask which Juner entity makes it and which measured properties belong to that combination.

EB-cured lightweight PV backsheet solution →
Juner's EB-cured lightweight PV backsheet uses a solvent-free coating cured by electron beam at room temperature, and was shown as an EB-coated flexible sheet in September 2026. Grade code, thickness, roll width, bend radius and barrier data are not published. To quote… [2]
Specifications & selection questions →Layer stack
CGN Juner backsheet: what each source describes
| Source | What it shows | Ask Juner for |
|---|---|---|
| Group solution page | An EB-cured lightweight PV backsheet. | The commercial grade and its support and coating structure. |
| 2026 exhibition report | An EB-coated lightweight flexible PV backsheet on show. | The quotation and sample revision that match the exhibited sheet. |
| 2025 CGF/PP paper | Uncoated support-sheet specimens with different additives. | Whether any tested formulation matches the support layer you are quoted. |
| Solution photo | White sheets, with no dimensions or lot number. | Thickness, width, delivery format and the batch behind your sample. |
The solution page gives no sheet dimensions, commercial SKU or qualification certificate, so all three belong in your quotation request. [2][3][4]
Coating and curing
How Juner describes the EB coating, and what to pin down
Solvent-free coating, cured at room temperature
Juner describes a solvent-free coating cured by electron beam at room temperature, with better coating and interface properties as the stated benefit. The page lists no dose, coating thickness, line speed or energy use. Request the controlled specification for the material you will receive. [2]
Finished sheet, support layer or development sample
Settle which of these you are buying. Ask Juner which steps are complete on delivery and which incoming or module-line checks fall to your own team. [2]
Juner's other composites are separate products
Battery-protection composites, modified nylons and honeycomb panels serve vehicles and other uses. Their fire-exposure, strength and weight-saving figures stay with those products; a backsheet enquiry needs its own numbers. [1][3]
Turning the 2025 study into questions
Using the CGF/PP aging study when planning backsheet tests
What the 2025 study tested
The paper ages uncoated continuous-glass-fibre/polypropylene sheets with a fixed lay-up and compares additive formulations under accelerated wet heat. It is useful background on interfaces and aging. The grade Juner quotes may use another formulation, so ask which one, if any, it matches. [4]
Plan tests on your real stack
Send Juner your module architecture. Ask for reports that cover the same support, coating, bonding materials and conditioning, that state which layer each result refers to, and that include before-and-after measurements. [2][4]
Service life comes from module qualification
Accelerated aging on a specimen tells you how that specimen behaved. Lifetime expectations for your module come from the qualification and extended reliability programme you agree with your test partners, with acceptance limits set in advance. [4]
From sample to repeat orders
Four steps from a Juner sample to repeat backsheet supply
Name the responsible company
Juner's parent company and its Zhejiang subsidiary are separate legal entities. Agree who issues the quotation, which site produces the sheet, who your technical contact is, who releases each batch and how changes will be notified. [1][4]
Sign off a sample specification
Get the grade and revision, layer stack, thickness tolerances, surface orientation, delivery size and storage instructions in one document, with measurable incoming-inspection limits. The marketing photo is no substitute for that document. [2]
Laminate and age real modules
Agree handling, preparation and bonding settings with your module plant. From that trial, record curvature, dimensions, bond condition and the agreed environmental and electrical results. [2][4]
Lock the approved build
Keep sample and component lots, process settings and reports. Write into the contract that changes to formulation, coating, layers, producing site or cure process need your approval before the next shipment. [2]
Project fit

Continue to sourcing requestBuyer questions
Can the 2025 CGF/PP paper stand in for a backsheet data sheet?
It describes uncoated support-sheet specimens. Ask Juner which formulation the coated commercial sheet uses and for test data measured on that sheet. [4][2]
Do Juner's battery-panel strength figures apply to the backsheet?
They belong to a vehicle battery-protection composite. Ask for the specification of the backsheet grade you select. [1]
Is Juner selling an electron-beam accelerator?
The solution entry covers a backsheet material made with EB curing. It lists no machine, price or configuration. If you need equipment or a coating service, say so in the enquiry. [2]
Which company signs the contract, the parent or the Zhejiang subsidiary?
The group page lists the Zhejiang company as a subsidiary. Ask Juner to name the contracting and producing entity on the quotation. [1][4]
What should a first sample request to Juner include?
Your module design, the target layer stack, the sheet size and the tests you plan to run. Ask for a numbered sample specification to travel with the sheet. [2]
