Improve Horizontal Flammability in Compounds using Vistamaxx™ Performance Polymers

Abstract:
The purpose of the paper is to describe the use of Vistamaxx™ Performance Polymerswith other polyolefin materials in formulations to improve the horizontal flammability results of those formulations.

Background:

For many years, flame retardant materials have been added to polyolefin formulations to increase resistance to ignition, suppress smoke, reduce flame spread, and prevent dripping which prevents the fires of articles made from polyolefin formulations. Flame retardants can be halogen or non- halogen depending on their composition. The quantities used in a formulation can vary depending on the flame specification. The cost of these materials varies from reasonable to very expensive depending on their composition. The cost and effectiveness of the flame retardant material dictates the economics of the final formulation.

VistamaxxTM Performance Polymers, commercially available from ExxonMobil Chemical Company in Baytown, Texas, may be added to polyolefin formulations to reduce the rate of burn of those formulations. It has been discovered that low levels of Vistamaxx are effective at improving horizontal flammability results. Vistamaxx dispersion capability plays a role in reduction of horizontal flame rate results.

Sample Data and Performance:

The formulations used in the study are listed in Table 1, with each component listed as a wt% based on the formulation.
