Rigid thermoplastics include both commodity thermoplastics
and engineering thermoplastics, such as polypropylene (PP), polystyrene (PS), high impact polystyrene
(HIPS), polycarbonate (PC), acrynitrile-butadiene-styrene (ABS), poly(ethylene terephthalate) (PET),
poly(methylmethacrylate) (PMMA), styrene acrylonitrile (SAN), poly(phenylene oxide) (PPO),
polyamide (PA), PC/ABS blend and PPO/PS blend etc..

Abstract
Introduction
Experimental
Material
Two classes of “universal overmolding TPEs” have been developed and used in this study.

Re-using post-industrial or post-consumer polyester regrind has typically been limited due to the adverse effects of heat and moisture on the virgin resin.
Cesa Extend Additives utilize an oligomeric reactant to repair the damage and restore the resin’s Intrinsic Viscosity (IV).
Processors can then use higher proportions of recycled resin while maintaining the same processing properties as virgin PET.

RejoinTM PCR Masterbatch uses PCR as a carrier resin, effectively allowing a bottle or part to be manufactured with 100% PCR.
Simplify the process to develop color in recycled resin for L’Oréal to achieve global color consistency, while working towards their 2030 objective to have 100% of the plastics used in its packaging be made from recycled or bio-based material.
Avient’s PCR Color Prediction Service helped L’Oréal simplify overall color development with recycled resin.

Made from polyphenylsulfone (PPSU) resin, Transcend Premier Healthcare Colorants, including pre-colored solutions, can withstand up to 1,000 autoclave cycles and high heat sterilization up to 150C.
These resins also maintain dimensional stability while providing chemical resistance against the effects of harsh cleaning agents.
Additional iterations are in development for other high-performance resins, including polyethersulfone (PES) and polysulfone (PSU).
