HYDEX® 4101 PBT black
HYDEX® 4101 PBT black is a PBT polyester thermoplastic that can withstand higher impact than PET polyesters and thus carries reduced risk of part breakage in operation. It is a plastic material that can meet ASTM requirements for PBT materials, and is ideal for machined parts in a variety of industrial settings. HYDEX 4101 black has excellent resistance to typical chemicals such as chlorine and caustic solutions and has a very low moisture absorption rate, as much as 15 times less than nylon.
