Series P05 · HJF / HJFS
Closed-Cell Silicone Foam,
Engineered for Sealing & Cushioning
YUTIAN produces closed-cell silicone foam tubes, strips and profiles with a wide, adjustable density window — sealing, cushioning and insulating everything from EV battery packs to electronics enclosures. Formulated and extruded in-house, with UL-94 flame-retardant grades.
Product Overview
One Foam Platform, Three Geometries
Foam sealing lives or dies by cell structure. YUTIAN closed-cell silicone foam keeps cells consistent and verifiable — confirmed by samples before production — so compression, recovery and sealing behavior stay predictable across your assembly.
With over 1,060 foam part numbers produced over the past decade, the platform spans standard cord and strip geometries to fully custom profiles.

Product Range
Foam Silicone Configurations
Tubes, strips and custom profiles in one foam platform. All series can be customized to your drawings.
Foam Cord & Tube
- Round cord and hollow tube for gap sealing
- Consistent cell structure, sample-verified
- Standard and custom diameters
Flat Foam Strips
- Die-cut or continuous strips for panel sealing
- Single/double-sided adhesive, 3M tape options
- Width and thickness per drawing
Custom Foam Profiles
- E-shape, P-shape, D-shape and custom sections
- Most standard profiles run on existing dies
- Non-standard dies quoted per drawing

Manufacturing & Quality
From Compound to Qualified Product
Three coordinated bases — raw material, functional compounds and precision extrusion — under one quality system.
Quality Control at Each Stage
- Incoming material inspection — compound properties verified before production
- Density & hardness verification — foam properties checked against specification
- Sample-confirmed cell structure — verified before volume production
- Final inspection & traceability — batch records from compound to shipment
Monthly averages: ≥ 95% self-inspection pass rate, ≥ 99% customer acceptance rate. In-house laboratory covering GC-MS, tensile, burst, thermal aging and UV weathering tests.
