Viscoelastic Foam Developmental Formulation
Northstar Polymers has done a research on viscoelastic foam formulations. Viscoelastic foam has a very unique rebounding property. When the foam is compressed bay a hand, it can leave imprint of the hand, and then it slowly comes back to the original shape. Viscoelastic foam has been used in a variety of applications such as toys, pillows, mattresses, and many other unique applications. This formulation is a starting point formulation for modification and development of optimum formulations to serve custom applications.
VEF-10
(Viscoelastic Open-cell Flexible Foam, Developmental Formulation)
VEF-10 is a viscoelastic open-cell flexible foam starting point formulation for custom applications. This foam can be modified to meet specific requirements for developmental and custom projects for various applications.
System Code: VEF-10
Components:
Part-A: MSA-018
Part-B: PPF-019
Mixing Ratio:
A: B = 1.000 : 3.300 by weight
A: B = 1.000 : 3.783 by volume
Processing Conditions
Component Temperature: Ambient
Mold Temperature: 100 - 120 °F
Mold Release: Non-silicone
Typical Compression Rate: 10%
Curing Pattern:
Pot-life: 40 seconds (pour within 30 seconds)
Demolding: 9 - 12 minutes
(The foam may need physical crushing to induce open-cell foam structure at 20 minutes point.)
