What are the advantages of using ABS raw materials in the field of medical devices?
Many medical devices are made of plastic materials. Compared with metal materials, plastic materials have unique advantages and can be better applied to various scenarios of medical treatment. Among them, ABS materials are used more. ABS has certain rigidity, hardness, impact and chemical resistance, radiation resistance and ethylene oxide sterilization resistance. The medical application of ABS is mainly used as surgical tools, roller clips, plastic needles, tool boxes, diagnostic devices and hearing aid shells, especially the shells of some large medical equipment.
ABS performance characteristics
1. ABS is synthesized from three chemical monomers, acrylonitrile, butadiene and styrene. The respective characteristics of these three components make ABS have good comprehensive mechanical properties. Acrylonitrile gives ABS good chemical resistance and surface hardness, butadiene gives ABS toughness, and styrene gives it good processability and dyeing properties.
2. The characteristics of ABS mainly depend on the ratio of the three monomers and the molecular structure in the two phases. This allows great flexibility in product design, and has resulted in hundreds of different quality ABS materials on the market.
3. ABS material has super easy processability, good appearance characteristics, low creep and excellent dimensional stability.
4. All kinds of ABS materials are easy to accept common secondary processing, such as machining, bonding, fastening, electroplating, painting, ultrasonic welding.
5. ABS has excellent impact strength and does not drop rapidly at low temperatures. It has good mechanical strength, hardness and certain wear resistance.
6. It has good cold resistance, oil resistance, water resistance and chemical stability. Water, inorganic salts, alkalis and acids have almost no effect on ABS, and will dissolve or form turbidity in ketones, aldehydes, esters and chlorinated hydrocarbons. Liquid, insoluble in most alcohols and hydrocarbon solvents, but will soften and swell with long-term contact with hydrocarbons.
