Visco elastic foam is a dense, flexible, open cell polyurethane foam that is more commonly referred to as memory foam. It is also known as temper foam, slow-recovery foam, low-resilience polyurethane (LRP) and visco foam. Visco elastic foam’s domineering characteristics are its ability to conform to the shape of whatever is placed upon it, and then recover to its original shape once that weight is removed. With its superior cushioning for even pressure distribution, it is a popular material for use in mattresses, pillows and furniture.
Visco elastic foam was invented by NASA during the early years of the space program. Improved technology has made today’s product far superior and more affordable.
Fabricating memory foam is a slower, more complicated process than the fabrication of conventional polyurethane foam. Its softness is a contributing factor that makes it a fabrication challenge. The material can be die-cut, but it does have fabrication limits.[ At Merryweather Foam, we take the time and used proven processes in creating our high-quality memory foam. We use no fillers.]….this sounds like foam manufacturer statement, not a fabricator statement.
Characteristics of visco elastic foam include:
- Shock absorption
- Sound absorption
- Mildew resistant
Memory foam is useful in a variety of applications:
- Safety equipment
- Audio equipment
- Sound Studios
Visco elastic foam resiliency and cushioning attributes make it a popular material for the medical industry, hospitality and marine sector and in acoustics and sound engineering. It is also widely used in footwear and toys. Unlike many foams, however, memory foam’s density generally makes it too heavy for wide-use in packaging.
Merryweather Foam offers visco elastic foam in a variety of stock options:
- Sheet stock
- Bun stock
- Pre-cut sheets
- Die cut
- CNC cut
Densities are available from 2 to 10 lbs. per cubic foot, with tensile strengths to 40 psi and elongation to nearly 200%. We have the capabilities to create quality memory foam that ranges in recovery times from very slow to extremely fast. Choose the formula that best suits your particular application.
Memory foam’s structure and slow recovery makes it a terrific material when sound or vibration dampening is required. It is also one of the world’s most comfortable materials.
