One-stage production uses only one set of molds and is considerably faster. Two-stage, as the name implies uses two sets of molds to manufacture the finished product.
 
- Advantages of one -stage foam:
 
· Less expensive; contains some recycled content
 
· One-stage foam has a higher compression deflection, leading to less compression of the foam during skiving, which allows tighter tolerance.
 
· The charcoal color tend to be darker and more consistent
 
- Disadvantages of one-stage foam:
 
· Material cell structure is slightly coarser, and has more pinholes on the surface
 
· Compression set is not as good as two-stage foam, so die cutting can be difficult
 
· Will not heat bond easily
 
· Color limitation; only available in charcoal

FAQs

Q: Do you manufacture your own foam?

A: Yes, we do manufacture the foam using our own presses and molds. We have various sizes molds.

Q: Why your price labeled so cheap?

A: We manufacture the foam buns our self, and export directly, no extra fees added.

Q: What is your lead time?

A: Ninety percent of all our orders can be loaded in 7 days.

Q: How much can you fit on a 40 HQ container?

A: Approximately 205 buns of 4" x 48" x 96"

Q: What is your minimum order?

A: We do not have a minimum order. However, small qty will be waste for the shipping costs.

Q:What are acceptable forms of payment?

A: We accept wire transfers, TT payment, Paypal, Western Union, LC etc.

Q: What densities are available?

A: We stock 1.5lb to 15lb densities.

Q: What colors are available?

A: Charcoal; Light Charcoal; Grey; Mint Green; Blue; White; Yellow; Red; Lavender; Lime Green; and Natural.

Q:Does your material come with skins?

A: Generally no, although some materials are available with skins upon request.

Q: What can be used to cut your foam?

A: Most tools that can be used to cut wood can also be used to cut our foam. These include table saws, band-saws, table routing, water-jet, etc.

Q: What is the working temperature of the foam?

A:Maximum continuous operating temperature of our foam is between -110°F to 180°F (-79°C to 82°C)

Q: What is the shelf life of the foam?

A: Crosslinked polyethylene foam does not have a shelf life.

Q: Does the foam float?

A: Yes, it does; XLPE is a water resistant foam.

Q: What are the differences between EVA and XLPE?

A: EVA stands for ethylene vinyl acetate. Our XLPE and EVA foam products are similar materials and are difficult to distinguish. 

The primary differences are that EVA is softer, more resilient, and has stronger recovery after compression. Whereas polyethylene foams are firmer and more resistant to heat. 

Both of them provide excellent protection and shock absorption for packaging applications.
