Rigid substrates include polypropylene(PP), polyethylene (PE), amorphous polar plastics such as polycarbonate (PC), polymethylmethacrylate (PMMA), polystyrene (PS), high impact polystyrene(HIPS), polyphenylene oxide (PPO), glycol modified polyethylene terephthalate (PETG), Acrylonitrile Butadiene Styrene (ABS), semicrystalline polar plastics such as polyester (PET, PBT) and Polyamide (Nylon 6, Nylon 66). The TPE compounds developed at GLS bridge the gap of the above chemistries and offer solutions to customers with adhesion requirements for substrates ranging from Polypropylene to Polyamide which represent the opposite spectrum of polarity.
