This new process allowed for the production of amorphous polyolefins on demand, independent of Eastman's facilities for producing crystalline materials. The first product from this new process was M-5H, which is now identified as Eastoflex P1023. These are important characteristics in a modifier for roofing asphalt. Initially designated M-5F, this product is now known as Eastoflex E1060. It is softer, lower in softening point, and more flexible than Eastoflex P1023.
Flexibility is another important requirement in a roofing asphalt modifier.
Accordingly, in 1987, Eastman introduced custom blends of P1023 and E1060 to provide a balance of properties tailored to meet customers' end-use requirements. As part of a continuing effort to integrate manufacturing capabilities with customer needs, Eastman Chemical Company has expanded the breadth and flexibility of its Eastoflex APO product line. Typical properties of the five APOs that currently serve as neat blending stocks are shown in Table 1. Properties shown in tables contained in this publication are for information only. Eastman Chemical Company makes no representation that the material in any particular shipment will conform exactly to the values shown.
