Paracril OZO is a fluxed blend of NBR and PVC. The most common ratio of NBR to PVC is 70/30. A higher PVC content of 40% is used in applications such as sponge where very low densities can be achieve through the uniform expansion of the chemical foaming agent. Paracril OZO offers inherent resistance to OZONE, good colorability, smooth surface appearance, abrasion resistance, processing ease, and flame resistance.
Plasticizer extended grades are also available that contain as high as 70 parts of phthalalate for low durometer rolls.
