This paper investigates the compression-compression fatigue behaviour of polyurethane
rigid (PUR) foams of three relative densities (RDs): 0.0854, 0.1239 and 0.2564 respectively …

In the foreseeable future, the development of petroleum-based polymeric materials may be
limited, owing to the gradual consumption of disposable resources and the increasing …

A new char-based insulation foam (CIF) is developed using coal-derived pyrolysis char (PC)
and lignin, a paper and pulp industry byproduct. In this study, CIF is prepared by adopting …

Alternatives to polymer reinforcement, adding value to agro-industrial byproducts, are
emerging to develop sustainable materials and cost-effective industrial applications. The …

The utilization of coconut diethanolamide (p-CDEA) as a substitute polyol for petroleum-
based polyol in fully biobased rigid polyurethane-urea foam (RPUAF) faces challenges due …

The use of metal catalysts during the production process of cellulose acetate (CA) film can
have an impact on the environment, due to their toxicity. Diphenyl phosphate (DPP) was …

Tannin-based foams have gained attention as a potential bio-based alternative to
conventional synthetic foams. Traditionally, namely condensed tannins (CT) have been …

The demand for sustainable and suitable materials for comfortable human life in the modern
