Dialyzers are necessary for the treatment of blood purification. It is vitally necessary to implement a mass-production system that reduces the time to market due to the supply chains’ and just-in-time inventory’s growing need.
To provide a resin composition material for the body and header of a dialyzer used for artificial dialysis, and to supply these dialyzer body and header, where the resin composition material excels in balancing its various physical properties such as transparency, shock resistance, and rigidity, and has good cutting workability.
The resin composition used to create the dialyzer body and header for artificial dialysis includes a block copolymer with 65 to 89 mass percent aromatic vinyl hydrogen carbonate and some mass percent conjugated diene, two or more aromatic vinyl hydrogen carbonate copolymer blocks, and two or more peak molar weights; and a resin based on styrene.
The transparency, stiffness, and -ray resistance of polystyrene are outstanding, but it is also readily shattered and has a low impact strength.
Impact-resistant polystyrene modified with rubber offers strong impact strength but is milky white and hence difficult to see inside the object.
Along with having exceptional transparency and impact resistance, polycarbonate resin also has the drawback of losing value after sterilising with an electron beam or gamma rays.
Materials for the main body and header of a dialyzer based on a thermoplastic block copolymer constituted of a vinyl aromatic hydrocarbon and a conjugated diene have been developed in response to the aforementioned issues with the prior art. a resin mixture containing a conjugated diene and hydrogen-based thermoplastic block copolymer
The Global dialyzer polycarbonate resin market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
In order to increase dialyzer production, Covestro offers quick colour recovery gamma sterilizable polycarbonate in an oxygen-free environment. When combined with Covestro’s mature dialyzer’s technical expertise & experience in China, Makrolon Rx2440 from Covestro quickly recovers from the yellowing colour following this new low oxygen, high energy sterilisation method. This allows them to reduce the production-to-delivery timeframe to increase productivity.
