Preparation of Moulding Resins from Inexpensive By-products: Substitution of Phenol Novolac with Unmodified Lignin in Moulding Resin and its Effect on Physical Properties of Mouldings

SYNOPSIS Mouldings of 25% resin content were prepared. Substitution of phenol novolac with various ratios of unmodified bagasse lignin was investigated. The effect of lignin incorporation on tensile and dimensional stability properties of mouldings was then studied. Low levels of lignin incorporation already seriously affected the properties of mouldings.
