Schmitt of the subject company, and the third is for your files. Six of the suggested formulations have been indicated by Mr. Schmitt as of sufficient interest as to be included in pilot plant trials at their Watertown, Massachusetts plant later this month. These formulations include "B", of 5 compounds evaluated in the initial trial at Lam-n-Hard with the continuous press on January 31 at Mr. Schmitt's request. The identity of several of the Union Carbide Corporation candi date materials in the reactive systems are: DQDA 3269 - medium molecular weight ethylene-vinyl acetate copolymer PKHH - Polyhydroxyether of Bisphenol A !JCC 042405 2- - to contact us.

McCoy SUGGESTED VINYL FLOORING COMPOUNDS for THE FLINTKOTE COMPANY Whippany, New Jersey Union Carbide Corporation - Chemicals and Plastics Division Research and Development Department Tarrytown, New York March 27, 1967 SUGGESTED VINYL FLOORING COMPOUNDS INTRODUCTION Nine modifications of a formulation as suggested by The Flintkote Company for a non-asbestos filled candidate vinyl type flooring have been developed and assessed, as requested. DISCUSSION - EXPERIMENTAL The subject modifications were designed to provide an assessment of reactive and non-reactive binder systems, at constant binder and filler levels, on processibility and physical properties of laboratory prepared tile samples. The formulations and processing conditions are shown in Table I. Formulations "A" and "B" are essentially the Flintkote suggested formulation and are based on two resin systems VSKK-10 and VSJD-10. Reactive vinyl binder systems as based on PKHH, a polyhydroxy ether, and collodial silica were prepared and based on formulations "A" and "B". The effect of two types of impact modifiers, an ABS (F) and an acrylate )G), on the "B" control were assessed. The influence of an acrylic-type vinyl processing aid (H) on the properties of the "A" control was also examined. Tile samples were also prepared with an ethylene-vinyl acetate copolymer hinder system as a replacement of the vinyl resin binder system in both reactive (K) and non-reactive (J) systems. All formulations processed satisfactorily at the indicated conditions that are patterned after those normally used by this laboratory in the preparation of vinyl asbestos tile samples. Some blistering was encountered in the preparation of the test specimens and may/may not influence the resultant physical properties. RESULTS justified. The test data are shown in Table II. The following comments appear Controls "A" vs. "B?' "A" is superior in resistance to short and long term indentation, recovery, tensile, elongation, and is higher in room temperature stiffness. A modification of the two resin systems, "C", to contain a 50/50 resin mix is inter mediate in most properties. Occ 042408 2- - Control "A" vs. "D" The reactive system "D" exhibits less resistance to inden tation and less recovery. Tensile, elongation, and room temperature stiffness, are slightly lower. Control "B" vs. "E" The reactive system "E" exhibits comparable properties in several instances. Recovery is slightly lower; tensile and room temperature stiffness are slightly higher. Control "IT vs. "F" The ABS impact modified system provides slightly less inden tation resistance, more recovery and is lower in tensile. Control "ff' vs. "G" The acrylate impact modified system provides slightly less indentation resistance, lower tensile, and higher room temperature stiffness. Control "A" vs. "H" The "H" compound that contains an acrylic type processing aid is comparable in indentation resistance, tensile, and elongation and is higher in room temperature stiffness. Controls "A" and "B" vs. "J" The two vinyl systems are more indentation resistant, higher in recovery and tensile, lower in elongation and room tempera ture stiffness than the non reactive ethylene vinyl acetate system. The toughness values, empirical intergrations of the area under the stress-strain curves, are nearly three times that of the vinyl systems, The above comments also relate to the reactive system "K". Control "]" vs, "K" The reactive system "K" is slightly more indentation resis tant, higher in room temperature stiffness, and lower in elongation and toughness. lire- 042409 - 3- CONCLUSIONS AND RECOMMENDATIONS The suggested vinyl formulations are indicated as within range of conventional domestic limits for current vinyl flooring. The reactive systems for both the vinyl and ethylene-vinyl acetate binders are not indicated as effective as postulated. Further effort may be required to optomize the formulation/processing conditions to achieve full utilization of the system. The thirty percent binder level for the ethylene vinyl acetate systems with this particular grade of polymer suggests that a lower binder level is feasible.
