HYDRO-CARBON 



One that under chemical analysis tests 99.84 per cent, pure; 

 that runs absolutely uniform in quality; that did not oxidize 

 when subjected to the elements for three years on the roof 

 of our factory, although the iron pan in which it was placed 

 was so affected that nothing but a few scales of rust was 

 left ; besides, the pan became so "rubbery" that the cakes 

 of Hydro-carbon were not affected by the sun's rays, in the 

 way of causing them to melt and lose their original shape, though the test lasted three summers. With the temperature at 4° F. 

 the material has practically the same degree of flexibility as in midsummer. It works best in compounding on red hot mill rolls, 

 not sticking as mixed or blended Hydro-carbons do, but instead is absorbed readily by the compound; its use tends to decrease 

 the time necessary to mill a batch, in addition to which it is rich in hydrogen and adds that element to a shoddy which is neces- 

 sary to insure perfect revulcanization. It is a direct aid to stocks run through a tubing machine and assists in calendering. Fin- 

 ished goods of which it is a part feel more "rubbery" and have longer life than goods made without it. 



"Pretty near ideal," you say. Yes, but our MALTHA Hydro-carbon is doing this for some of the largest rubber man- 

 ufacturers in this country every day. May we not send you a free working sample to try out and prove it for yourself? Write 

 to-day.
