Packaging Foam System

In-situ foaming PU (two-component pour-in-place system)

Form: A component and B component are mixed on site for foaming, achieving in-situ forming with seamless bonding.
Features: 100% conformal fit for complex shaped parts, high strength fixation, moisture and dust resistance; suitable for large-size and irregular-shaped articles.

1. Superior Cushioning: 

Tunable energy absorption capacity; better drop and vibration resistance than EPS and EPE.
 

2. Moisture-proof & Thermal Insulation: 

Rigid closed-cell foam features low thermal conductivity, ideal for cold chain applications. Open-cell flexible foam provides air permeability while closed-cell foam delivers moisture resistance.
 

3. Eco-friendly & Safe:

 Low VOC; compliant with RoHS, REACH and SGS certifications; food contact grade available.
 

4. Flexible Molding:

 Supports cutting, molding and pouring; adaptable to arbitrary geometries with high efficiency for both mass production and custom orders.
 

5. Durable & Stable:

 Aging resistant, oil resistant and tear resistant; non-collapsible and deformation-free under long-term load bearing.
 

6. Relatively High Cost:

 Higher cost compared with EPS / EPE; ideal for mid-to-high-end and high-value products.

1. Electronics & Electrical Appliances: 

Inner liners for mobile phones, laptops and precision instruments; anti-static trays.

2. Cold Chain Logistics:

 Insulation boxes for fresh produce, vaccines and pharmaceuticals; thermal insulation layers for refrigerated vehicles.

3. High-value Articles:

 Shock-absorbent packaging for jewelry, watches and artworks; gift box inner liners.

4. Large-size Industrial Articles:

 On-site foaming fixation for automotive components, medical equipment and large-scale molds.

5. Food & Pharmaceuticals:

 Oil-resistant fresh-keeping films, moisture-proof pharmaceutical bags, inner wall coatings for cans.

1. Low density & High strength:

 Density ranging from 6–25 kg/m³, delivering lighter weight with enhanced mechanical performance.

2. Environmental orientation:

 Bio-based polyols, degradable formulations, low VOC flame retardant systems.

3. Multi-functional Integration:

 Integrated materials combining cushioning, anti-static, flame retardant and antibacterial properties.

4. Process Upgrading: Automated cutting, high-pressure on-site foaming.
