THE INDIA RUBBER WORLD 



[Ap 



PEACHEY COLD CURE PROCESS. 



S. J. Peachey was billed some months ago to give a paper be- 

 fore the Manchesler Section of the Society of Chemical In- 

 dustry, descriptive of his new process of cold curing rubber 

 without the use of bisulphide of carbon and chloride of sulphur. 

 It is now announced, however, that the paper which was to have 

 been given on March 4, has been postponed to some unknown 

 date, owing to certain circumstances which were not disclosed. 

 I may say that the process is decidedly novel and of great pros- 

 pective interest and the delay in publication may have something 

 to do with the patent which I understand is being applied for. 

 GLUE IN RUBBER. 

 The use of pitch bodies in rubber seem to have licen developed 

 in America and now. according to the interesting article on the 

 estimation of glue in rubber in the January number of The India 

 Rubber World, glue must be added to the rubber analyst's wor- 

 ries, as it appears to have come to stay in American rubber mi.x- 

 ings. I don't profess to be omniscient, and because I have not 

 come across its use in rubber in England the statement must not 

 be taken to mean that it is not already in regular use here. One 

 thing against it, I imagine, is the rise in price which has occurred 

 'and the lower quality of the bone glue which is in the market 

 to make up for the deficiency of hide glue. 



In certain classes of goods glue and rubber come into close 

 juxtaposition, but are not admi.xed. I notice that in "Crude Rub- 

 ber and Compounding Ingredients," by Henry C. Pearson, it is 

 stated that glue is used in bookbinder's cements, cheap frictions 

 and cheap horse-cover compounds with rubber. This is interest- 

 ing but presumably the "cheap" refers to pre-war days. 

 COLLOID CHEMISTRY. 

 This is not an inappropriate subject to come after glue, though 

 the only thing I have to say here about this difficult matter is 

 that it has been decided to found a professorship of colloid chem- 

 istry at Manchester University, the first professorship of its kind 

 in the world. A sum of i25,0O0 is required for the endowment, 

 of which I believe about one-half has been raised by cotton 

 interests, Tootal Broadhurst Lee Co. being much to the fore 

 in the matter. .\s far as local conversation goes, colloid chem- 

 istry means the chemistry of cotton, though readers of this 

 journal have usually associated it with rubber, glue, resins, etc. 

 It will be interesting to see to what extent the new professor 

 will apply himself to problems connected with rubber. 

 ZINC SULPHIDE. 

 I was interested in a recent letter in The India Rubber World 

 from a maker of zinc sulphide who stated that the works in Cali- 

 fornia are ready to turn out much more if only the rubber trade 

 would give the orders. That is the rub. Despite paragraphs in 

 various rubber books extolling the virtues of zinc sulphide, the 

 demand from the trade has hardly increased at all in the last 

 thirty years, the total consumption being almost negligible, as 

 rubber chemicals go in these days. Of course, in later years a 

 good deal has been used in the compounded form of lithopone 

 and it rather looks as if the extended use of lithopone is all 

 against the employment of zinc sulphide to a greater extent, 

 except in cases such as dental rubber where barytes would be 

 quite inadmissible. 



SLATE POWDER. 

 A company has been formed to market refuse Welsh slate 

 in the form of a very fine powder for use in compounding in 

 the rubber and other industries. Silicates such as fine while 

 clays have certainly come into use in the rubber trade in the last 

 few years to a greater extent than formerly and there may be 

 a future for the new Welsh product. 



FRENCH RUBBER ASSOCIATIONS. 



TiiF. 1-RENCH rubber manufacturers have not formed z. single 

 large corporation like The Rubber Association of America, 

 but have preferred to join a series of groups comprising those 

 interested in each specialty. The following is a list of these 

 associations, with their addresses: 



Chamhre Syndicale des Tissus et du Caoutchouc (fabrics and 



rubl)er), 8 rue Montesquieu, Paris. 

 Chambre Syndicale des Linoleums, Toiles Cuirs et Toiles Cirees 



(linoleums, artificial leathers, and waxed fabrics), 32 rue 



Ampere, Paris. 

 Syndicat de Toiles Circees et Produits Similaircs (waxed fabrics 



and like products). 11 rue de Turbigo, Paris. 

 Syndicat des .'\ppareils de Chirurgie (surgical appliances), 20 



rue Serpente, Paris. 

 Syndicat des Acessoires de Chirurgie et d'Hygiene (surgical 



and hygienic accessories), 163 rue Saint Honore, Paris. 

 Syndicat de Fournitures d'Usines (factory appliances), 163 rue 

 ^ Saint Honore. Paris. 

 Chambre Syndicale des Vetements en Caoutchouc et Imper- 



meables (rubber clothing and waterproofs), 163 rue Saint 



Honore, Paris. 

 Syndicat des .'Kntiderapants (non-skid devices), 39 rue de Cha- 

 teau Landon, Paris. 

 Syndicat de Caoutchouc et de Linoleum '(rubber and linoleum), 



18 rue Duphot, Paris. 

 Syndicat des Fabricants de Celluloid (celluloid products), 7 rue 



du Jong, Paris. 

 Syndicat des Planteurs de Caoutchouc de I'lndo-Chine (rubber 



planters), Saigon. French Indo-China. 

 Syndicat des Planteurs de Caoutchouc (rubber planters), 48 



Place de Meer. Antwerp. 

 Syndicat des Ingenieurs, Chimistes, Chefs de Fabrication et Con- 



tremaitres de I'lndustrie du Caoutchouc (union of engineers, 



chemists, factory heads and foremen in the rubber industry), 



49 rue des Vinaigriers, Paris. 



The most important associations are the Chambre Syndicale 

 des Tissus et du Caoutchouc, of which Mr, Yung is president 

 and which comprises all the great French manufacturers such 

 as Michelin, Bergougnan, the Societe Parisienne, the Societe 

 des Telephones, etc., and the Syndicat des Planteurs de Caout- 

 chouc de rindo-Chine. 



William Boyd Stacker has become connected with Geo. 

 Hankin & Co.. 27 Mincing Lane, London, E. C. 3, in a responsible 

 position. Mr. Stocker has been identified with the rubber, 

 balata, and allied trades for a number of years. 



THE RUBBER TRADE IN JAPAN. 



By Our Regular Correspondent. 



AMONG the many manufacturing industries which arose in 

 Japan during the Great War, the rubber industry must be 

 reckoned among the most promising. Before the war it 

 had been developing gradually, but with the outbreak of hostili- 

 ties the demand for Japanese rubber articles rapidly increased. 

 Since then, too, the use of rubber goods has become more wide- 

 spread throughout the Orient. Prior to the war South America, 

 Canada, .Australia, India, China and the South Sea Islands had 

 been supplied with rubber articles of British or German make, 

 but the opening of hostilities curtailed or altogether stopped these 

 supplies. Consequently articles made in this country have come 

 to be exported, especially balls, sheets, hose and toys. These 

 articles had not before been extensively manufactured in Japan, 

 but rubber manufacturers had to produce them to meet the home 

 demand, and exportation followed as a natural consequence. 

 THE TOKIO RUBBER ASSOCIATION. 



The first general meeting of this association was held on Janu- 

 ary 13, 1919, with many prominent officials in attendance, in- 

 cluding the deputy of the Minister of Agriculture and Commerce. 

 Since the establishment of the association a year ago its principal 

 activities have been many and important. 



On August 5 the officers' meeting was held at the office of the 

 association, when it was decided to raise prices of general rub- 

 ber manufactures by 20 per cent owing to high prices of naphtha, 

 textiles and wages. But 20 per cent has not proved sufficient and 

 urgent measures are required. Though it is difficult for all manu- 

 facturers to make uniform prices inasmuch as the prices must
