Due to contact with drug solutions or human bodies, the basic requirements of medical plastics are chemical stability and biological safety. In short, the plastic components cannot be deposited into the drug solution or the human body, will not cause toxicity and damage to the tissues and organs, and are harmless to the human body, non-toxic and harmless. In order to ensure the biosafety of medical plastics, medical plastics usually sold on the market have to be certified and tested by medical authorities, and users are clearly told which grades are medical grades.
PS is the third largest plastic variety after polyvinyl chloride and polyethylene. It is usually used as one-component plastic for processing and application. Its main characteristics are light weight, high transparency, easy dyeing, good molding and processing properties, and wide application. In daily plastics, electrical appliances, optical instruments, and cultural and educational products, the texture is hard and brittle, and the thermal expansion coefficient is high, which limits its application in engineering. In recent decades, modified polystyrene and styrene-based polymers have overcome the shortcomings of polystyrene to a certain extent, and K resin is one of them.
After general medical products are synthesized by injection molding, they are all flour-like powders in the synthesis tower of a large petrochemical plant, which cannot be directly used to produce products. This is the same as the composition of fat extracted from tree sap, also known as resin, also known as Powder, this is a pure plastic, with poor fluidity, low thermal stability, easy aging decomposition, and not resistant to environmental aging. In order to improve the above-mentioned defects, people add heat stabilizers, anti-aging agents, anti-ultraviolet light agents, plasticizers, etc. to the resin powder, through granulation modification to increase fluidity, and produce special properties suitable for various processing techniques. Different grades of plastic varieties. Therefore, the same type of plastic has multiple grades. According to the processing method, there are injection grade, extrusion grade, and blown film grade; according to the performance characteristics, it has high hardness and toughness. The plastic materials commonly used by medical device manufacturers are plastic particles that can be used directly after modification. For products with special performance that are not available on the market, the equipment factory of Medical Mould can introduce granulation production lines and processes, and design and produce plastic granules through different formulations.
