MCG-1 has its solid hardness range below Shore OO 1 hardness, or in Shore OOO scale range. This allows a manufacturer to use the molded part at OOO scale without plastic film or coated fabric. Whereas typical polyurethane gel materials have solid range between Shore OO 10 to OO 40 hardness, and if the mixing ratio is modified to obtain a softer range product, the material starts to sag like thick liquid, MCG-1 can service even lower hardness range without being liquid.

Another property that is unique to this gel is that since it contains some bubbles inside, it has a property to contract down from the original volume when a deflection force is applied. Regular gel materials do not contract within the same space and need expansion space to deflect, thus typically they are not appropriate for upholstery application. MCG-1 contracts up to a certain point without needing expansion space, thus it can be used as upholstery and bedding applications conveying its softness.

The cured part can be directly covered with Spandex type fabric; this allows the part to directly convey the softness of the gel.

Suggested applications include:

• Cushioning and padding parts for sporting goods and medical devices
• Upholstery application
• Human-fat simulating products (for doll skins, external breast augmentation etc.)
• Shock absorbing products
• Seating products

This polyurethane gel material is formulated in such a way that the user can control/choose the hardness/deflection properties of the product. Following is reference for the hardness to the corresponding mixing ratio.
