Novel Thermoplastic Natural Down Powder Film with High Mechanical Properties

Abstract

Superfine down powder was modified by formamide which acts as a plasticizer and then hot-pressed into thermoplastic down films. The influences of formamide content, hot-pressing time, pressure intensity and exposure to atmosphere on the mechanical properties of thermoplastic down films were investigated. The maximum tensile strength of thermoplastic down films can reach 28.74 Mpa after exposure to atmosphere for 40 days.
