The Influence of Rotational Molding Cycle on the Morphology and Physical Properties of FR-LLDPE

Abstract

The major objective of the study was to develop formulations having maximum impact strength while maintaining a UL-94 V-0 flammability rating. Excellent impact strength and flammability performance were achieved in the modified FR-LLDPE system at 20% impact modifier (ethylene copolymer), 22% flame retardant, 5.5% antimony trioxide, 0.25% PTFE, and 0.5% functionalized silicone additive. This paper further explores the performance of the aforesaid optimized FR-LLDPE composition when rotomolded at various cycle times. Attempts were made to probe the influence of morphological characteristics on the physical properties of the rotomolded parts.
