About Sulfycor
Founded in 2015, Sulfycor operates a magnesium oxide board factory in China focused on magnesium oxysulfate (chloride-free MgO) board manufacturing for international project supply, with a 50,000 m² production base and standard-board capacity up to 30,000 m² per day.
MOQ: 1 × 20GP container
Since 2015
Focused magnesium oxysulfate board manufacturing and export experience.
EN · ASTM · AS Testing
Board samples evaluated using applicable EN, ASTM and AS test methods.
30,000 m² / Day
Stated capacity for standard boards under planned operating conditions.
50,000 m² Base
Production space for forming, curing, cutting, finishing, QC and packing.
Three Product Systems
Sulfycor supplies three distinct magnesium oxide board series rather than treating every application as one generic board.
Ready-faced boards for wall sheathing, fire-rated ductwork and SIP panel facings.
Sanded boards for underlayment and specified structural subfloor assemblies.
Melamine- or HPL-faced panels for finished interior and modular-house walls.
Application-Based Supply
The same generic “MgO board” description is not enough for every project. We review the intended role, board thickness, size, surface, quantity, destination and requested performance documentation before quotation.
Production View
Review production footage from material preparation through board forming, curing and finishing.
Quality Evidence
Relevant documentation is matched to the selected board, thickness and intended application—not assumed from a logo alone.
European Fire Classification
A magnesium sulfate board sample was classified A1 for reaction to fire in a Sulfycor-applicant report.
Surface Burning
An approximately 12 mm board sample was evaluated for flame spread and smoke development.
Non-Combustibility
An approximately 12 mm magnesium oxide board sample was tested in 2025.
Physical Performance
Physical properties including strength, durability, water tightness, fixing and impact performance were evaluated.
Results apply to the specific samples or assemblies tested. Report scope and product specifications are confirmed for each project. Certificates and declarations from previous customer projects were held by those customers.
Manufacturing Capability
Board forming, curing, cutting and finishing are organized around the agreed board type, thickness and dimensions.
Raw materials, board dimensions, appearance and relevant performance requirements are checked against the confirmed order specification.
How We Work
Share board use, size, thickness, quantity, destination and required standards.
We identify the relevant product series, surface and available specification options.
Samples and applicable test reports can be reviewed before the order is confirmed.
Production, quality checks and export packing follow the confirmed order requirements.
The Next Step
Tell us what the board must do in the assembly. We will identify the relevant series and prepare the next technical or commercial step.
