A survey of the Material Safety Data Sheets and Technical Data Sheets from leading foam manufacturers reveals the use of the ingredients found in Table 1.

Occupational and nonoccupational exposure to hepatotoxic agents can lead to acute, subacute, or chronic liver injury.

Stated briefly, qualitative and quantitative analyses of risk leading to the conclusion that ETS exposure results in excess cancer death are based on assumptions and derivations which are supported neither by the data nor appropriate risk analysis technique.

Since both the UCC and NIOSH studies selected samples of the UCC Texas City employee population to serve as "controls," both studies are subject to some degree of sampling error that could lead to spurious results.

Patent Department Avenue de Tervuren 270-272 Letter Box No 1 1150 Brussels Friction material composites containing crystalline phosphate fibers and a process for the preparation thereof Asbestos friction material composites containing asbestiform crystalline calcium M phosphate fibers wherein M is a metal cation selected from the group consisting of sodium and lithium and mixtures thereof are useful as brake pads brake linings clutch facings and the like where friction material composites are needed Such composites are prepared by a blending asbestiform crystalline calcium M phosphate fibers wherein M is a metal cation selected from the group consisting of sodium and lithium and mixtures thereof a thermosetting based binder e@ AZ particulate friction modifier and a particulate inorganic filler to form a uniform mixture b placing the mixture within a mold cavity having a shape approximately that of the desired composite and c compressing the mixture at a tempera- 989 ture and a pressure and for a time sufficient to form the asbestos friction material composites 194 " HE -1- 60460 94989 FRICTION MATERIAL COMPOSITES CONTAINING CRYSTALLINE PHOSPHATE FIBERS AND A PROCESS FOR THE PREPARATION THEREOF BACKGROUND OF THE INVENTION Field of the Invention This invention relates to asbestos friction material composites and a process for the preparation of such composites More particularly this invention relates to asbestos friction 10 material composites containing asbestiform crystal- line calcium M phosphate fibers wherein M is a metal cation selected from the group consisting of sodium and lithium and mixtures thereof and a process for the preparation The friction material composites are 15 suitable for use as brake pads brake linings clutch facings and other similar uses where friction material composites are needed Description of the Prior Art Friction material composites for use as 20 brake elements in automotive truck bus or similar vehicles are known in the art In general such com- posites contain asbestos fibers as an inorganic fibrous reinforcement material The popularity enjoyed by asbestos fibers for such uses resides in 25 the fact that asbestos has been considered to be relatively inexpensive is easily preformed and pro- vides a brake element having excellent wear durability friction and strength properties However asbestos has recently been found to expose workers 30 making or installing the brake elements as well as the public to a potentially serious health hazard It has been determined that the inhalation of small asbestos fibers can result in a disease known as asbestosis in which these fibers accumulate in the 35 lungs scar lung tissue and cause many respiratory problems It has become increasingly clear that 0194989 -2- 43-21 inhalation of asbestos fibers over an extended period of time can lead to a cancer of the lining of the lungs known as mesothelioma as well as lung cancer 10 15 20 25 30 In addition in the operation of conventional asbestos- based brake some of the elements as the brake element wears away asbestos discharges into the atmosphere in its fibrous form to thereby pose a potential hazard In view of the potential hazard of asbestos material it has become increasingly desirable to find substi- tutes for asbestos in those applications involving the manufacture and use of materials containing asbestos and more specifically for manufacturers of friction materials such as asbestos brake elements to find suitable substitutes for asbestos U.S.
