“Naturally non-flammable” cellulose fibres in PBT

An article in Kunstoffe International presents successful development of high performance, fire resistant electrical components using bio-sourced cellulose fibres and PIN flame retardants.

Purified natural cellulose was regenerated (processed into a filament yarn) to improve mechanical performance, and used in PBT polymer (polybutylene terephthalate) with PIN flame retardants AlPi (aluminium diethyl phosphinate) and MPP (melamine polyphosphate) to achieve UL94-V0 (1.6mm) and good mechanical performance (tensile strength, elongation at break, notch impact strength, tensile modulus). Industrial parts such as cable guides for lights have been produced.
