CIRCOSOL - 2XH OFFERS 5 ADVANTAGES AS ELASTICATOR
FOR GR = S . . . REGULAR AND COLD Increased use of synthetic rubber makes t h e unique elasticator Circosol-2XH increasingly important to compounders 3 . HIGH NAPHTHENICITY
1. SPECIALLY REFINED FOR RUBBER-PROCESSING
Leading rubber technologists are unanimous in agreeing t h a t hydro carbons with a high degree of naphthenicity are best suited for processing and plasticizing rubber. Sun's exclusive refining process retains the high naphthenicity of the selected crudes from which Circosol-2XH is derived.
Circosol-2XH is not an ordinary mineral oil. It's a petroleum-base process aid, refined \>dthin rigid specifications solely to meet the exacting requirements of rubber compounders. Tlie product is a heavy viscous liquid, clear, trans parent, and with a pale green color as observed by transmitted light. I t is composed of hydrocarbons of c o m p a r a t i v e l y high m o l e c u l a r weight entirely derived from se lected crude petroleums. Its low volatility precludes any fuming and losses during mixing in the banbury and processing on the mills.
4 . CAN BE USED WSTH ALL COLORS Unlike products offered in com petition with it, Circosol-2XH is a light-colored compound- I t can therefore be used in such items as white footwear, hospital sheeting, white seals and gaskets.
5 . GIVES GR-S EXTRA RESILIENCE
2 . ASSURES PRODUCT ϋλΙΙΕΑΟΜΙΤν
Circosol-2XH improves t h e re bound so necessary for many uses. F u r t h e r m o r e , h e a t b u i l d - u p is low — in tire tread extrusion, for example.
Circosol-2XH is refined u n d e r precision-controlled conditions permitting no deviation from spec ifications. I t iiiininiizes the danger of product variation. To quote the technical superintendent of a large rubber company: "With Circosol2XH you never have to worry about results being different."
