Abstract

For given end-uses there are basically three strategies for minimising polymer consumption: redesign of the original articles, recycle for re-use, and recycle for reprocessing. Results are presented relevant to all three strategies in blow moulded and injection moulded articles. In thermoplastic packaging, discrete long-glass fibre compounds allow redesign to thinner sections and higher operating temperatures, while retaining acceptable impact strength. Re-use in the food packaging chain is increased by higher heat distortion temperatures to meet sterilisation requirements. The SAFIRE long-fibre compounding technology extends the range of high value outlets for reprocessed mixed recyclates by increasing their strength, stiffness, heat distortion temperatures and creep resistance.
