Photovoltaic encapsulation
Clean film starts with a workable resin.
High-VA options to shortlist for encapsulant recipes where extrusion, optics, adhesion and cure behavior must work together.
Ethylene Vinyl Acetate Copolymers
Material clarity.
Industrial scale.
Start with what you are making. Then compare VA content, melt flow and end use across a Lianyungang-made EVA portfolio built for solar film and industrial formulations.

Start with the process
A grade list is useful.
A clear choice is better.
Two numbers can narrow the field, but they do not finish the job. Start with the product, the equipment and the result you need; then use the grade data to plan a sensible trial.
Build a shortlist ↗
01
Built around solar film
PV-linked grades backed by independently developed process know-how.
02
Enough range to compare
18–40% VA and melt flow references from 0.2 to 400 g/10 min.
03
Made inside one system
Olefin production and EVA manufacturing connected in Lianyungang.

Applications
What does the resin
need to do on your line?
The same EVA number can mean something different in solar film, adhesive, foam or cable. Start with the job.
01 / 04
Hot-melt adhesives
Match the flow to the application method.
Medium- to very-high-flow options for packaging, woodworking, bookbinding, sealants and other hot-melt recipes.
Foam & footwear
Choose the feel, then prove the foam.
Flexible grades to test in cross-linked foam, footwear, cushioning and sport-material compounds.
Wire & cable
Build flexibility into the compound.
Low- to medium-flow grades to evaluate in flexible cable compounds and filled formulations.
Made in Lianyungang
Range comes from
how the site is built.
Two high-pressure polymerization routes, integrated olefin supply and application work give Sailboat room to serve very different processing windows from one manufacturing base.

01
Two EVA process routes
Autoclave and tubular lines cover very different combinations of VA content and flow.
02
Solar-grade process work
Independently developed photovoltaic EVA technology underpins the solar-linked grade range.
03
POE alongside EVA
A reported 100,000 t/y POE unit adds another material route for encapsulation projects.
Capacity, as of June 2026
900,000
tonnes of EVA per year
Integrated in Lianyungang
Big numbers matter
only when the resin is dependable.
The Xuwei site connects EVA production with a larger olefin system. For customers, the point is straightforward: more room to plan production, manage supply and keep grade discussions tied to a real manufacturing base.
2.4mt/y MTO capacity
700kt/y PDH capacity
100kt/y POE capacity
Better operations
Use less guesswork.
Learn from every run.
The work is practical: watch the process more closely, act on better data and find useful routes for carbon that would otherwise remain a waste stream.
Carbon back into the value chain
Shenghong's green-methanol route uses captured industrial CO₂ as a feedstock for downstream materials.
Data that reaches the plant floor
Digital twins, automated inspection and process analysis give operators earlier, clearer information.
About Sailboat
The company is Sierbang.
The name many customers
know is Sailboat.
Founded in 2010, Jiangsu Sierbang Petrochemical is part of Eastern Shenghong. Its Lianyungang base makes EVA and other olefin-derived materials used in solar energy, manufacturing and everyday products.
