Vinyl films plasticized with Santicizer 141 help prevent fires caused by accident or carelessness.

Large-scale production of SANTICIZER 141, fire-resistant plasticizer for vinyl films

New production facilities assure ample supplies of Santicizer * 141. This new Monsanto product combines into one plasticizer:

FLAME RESISTANCE - Unmatched by other equally efficient plasticizers. Eliminates the need for expensive pigment fire-retardants. LOW-TEMPERATURE FLEXIBILITY - Vinyl articles containing this plasticizer remain flexible at low temperatures. Equal or superior to the most commonly used vinyl plasticizers.

LIGHT STABILITY-Plasticized vinyl compositions age 25-50% longer. Flexibility and color are

retained without embrittlement or
tackiness.

LOW TOXICITY-Tests show
Santicizer 141 to be one of the least
toxic of all plasticizers.
Shipment can be made immediately in
tank car, drum car or LCL lots.
