Ecomax™ 5188A

Provides cost saving and gloss reduction for replacement of IP EVA/POE foam in footwear applications without trade-offs on properties.

Additional benefits include:
• Minimum 15% cost savings through lower price of the product & improved productivity
• Environmentally friendly with acceptance of recycled EVA foam scrap
• Reduction of raw material cost with a higher acceptance amount of recycled EVA foam scrap.

Material Features

• Gloss reduction
• High resilience
• Thermal stability
• Good adhesive bonding

Target Applications

• Sock-liner
• Midsole(die-cut)
• Sandal
• Industrial foam

Typical Properties

• Density (g/㎤): 1.86
• Melt Flow Index (g/10min): 1.0~2.0
• Melt Point (℃): 93
• Hardness (Shore D): 40~42

Use Recommendations

• For use as a replacement of EVA or POE at 30 ~ 50 phr
• Decrease dosage for blowing agent(20%) and DCP

Ecomax™ 5188A can be processed on equipment normally used for EVA.
Sufficient time and temperature must be applied to get good melting and dispersion of the EVA, scrap, Ecomax™ 5188A and other ingredients.
Best processing and properties were achieved under the following conditions:
• Control kneader mixer temperature at 80℃
• Charge all ingredients(except DCP and blowing agents) to mixer
• Mix to 115℃ (temperature increase from shear rather than applied heat, if possible)
• Add more compounds into press mold (6~12%)

Troubleshooting Guidance

1) Pin hole or air jacket
• Cause: Over curing
• Solution: Reduce DCP dosage, Decrease molding temperature
2) Foam surface not smooth
• Cause: Insufficient flowability
• Solution: Increase processing temperature, Reduce DCP dosage(slightly)
3) White spot on the foam
• Cause: Insufficient mixing
• Solutions: Increase mixing time, Add lower melting materials at the end of processing

 

Ecomax™ 8000

Provides cost saving benefits through higher expansion of molded EVA foam including EVA scrap containing formulations without trade-offs on properties.

Additional benefits include:
• Minimum 15% cost savings through lower price of the product & improved productivity
• Environmentally friendly with acceptance of recycled EVA foam scrap
• Reduction of raw material cost with a higher acceptance amount of recycled EVA foam scrap.

Material Features

• High expansion
• Increased Melt Strength
• Better adhesive bonding
• High resilience
• Light weight
• Good compression set

Target Applications

• Midsole(die-cut)
• Athletic shoes die cut mid sole foam and insole foam
• Sandal foam
• Other Industrial foam

Typical Properties

• Density (g/㎤): 1.46
• Melt Flow Index (g/10min): 1.5
• Melt Point (℃): 90~110
• Hardness (Shore D): 48

Use Recommendations

Improved dispersion by increased Ecomax™ 8000 dosage
1) Scrap portion : 20 Phr
2) Ecomax™ 8000: 0, 5, 10, 15 Phr

• Weight amount of calendered sheet stock to be put into the compression mold should be increased 5% otherwise foam will be under-cured due to the low weight of sheet stock.
• With 10~15 phr of Ecomax™ 8000, foam molding can achieve 200~220% expansion ratio to maximize cost saving benefits providing 15~20% higher production yield (bigger foam can produce 6~8 pairs more of die cut foam per foam sheet)
