Tough and chemical resistant PC-PBT blend / Formulated using Covestros Makroblend® resin.
Polymaker™ PC-PBT is a PC/PBT polymer blend which offers good heat resistance and toughness at low temperature (-20˚C/-30˚C). Polymaker™ PC-PBT also features good chemical resistance.
Polymaker™ PC-PBT is resistant to hydrocarbons, alcohols, organic acids, inorganic aqueous salts, and mild base and acid solutions. This makes them suitable for applications requiring resistance to intermittent contact with many lubricants, solvents, fuels, oils, cleaning agents, and other automotive-type chemicals. Additional influence parameters of the chemical resistance properties of material are the: Composition of the surrounding media, temperature and duration of exposure. It is essential to test them under actual operating conditions first.
