The polyether polyols based exclusively on ACN are commercialised because of their high glass transition temperature (T ) of the polyacrylonitrile solid fraction. However, they are not used for production of slabstock foams, but for PU elastomers (microcellular elastomers for shoe soles) and integral skin foams. [Pg.191]

Figures 13.4 and 13.5 show a comparison of wear properties and densities of some common shoe-soling materials the high rating of PU is clear to see. However, important as this list is, there are some disadvantages. The dominant one is cost. Polyurethanes are made from inherently expensive materials. Machinery and moulds were initially very expensive. These cost factors have improved since the early days the cost differential of more highly processed raw materials decreases as oil price increases raise the cost of basic petroleum products, and machinery costs decline as techniques are improved and as more units are required. Thus, the price of a PU foam shoe bottoming machine declined from c.a. 40 000 to 15 000 at 1973/74 prices also the cost of mould making has been halved, with the advent of metal spraying and electro-plating techniques. Nevertheless, the cost of PU soles is high, and they find their outlet in better-quality men s and children s shoes, and industrial footwear.

PPVC is blended with high-molecular-weight elastomeric materials, such as nitrile rubber (NBR), EVAC and polyurethane (PU), to improve the shock resistance of flexible compounds. PPVC/NBR blends have good oil resistance and are used to make industrial boot-soles and in some electrical cable applications. PVC/EVAC and PVC/PU are used in shoe-sole formulations. [Pg.133]
