Chinese medical plastics industry analysis
Medical plastic products industry in China through the rapid development in recent decades, has been increasingly mature, but because starts late, combined with the related technical field and basic industrial level is limited, the China medical plastics industry level compared with the world's advanced level there is still a considerable gap.
Innovation ability is weak
Chinese medical plastic products enterprises in technology innovation ability is poor, and products with independent intellectual property products.
Based industrial raw materials, due to the backward, the raw material for medical plastic products category is not complete, the quality standard is not standard, lack of development of medical plastic raw materials, lead to the high-end products of raw material for domestic still mainly rely on imports.
New type of plastic medical development
In recent years, some have the good performance of new synthetic materials emerge, greatly enrich the varieties of medicinal plastic at present. Such as: PHILIPS company K resin has good impact strength, improved the brittleness of polystyrene, also can adjust the hardness of the material, at present, both at home and abroad have begun to replace polyvinyl chloride (PVC) used in disposable infusion sets. Polyvinyl chloride (PVC) has a wide application in medical field, but the products of DOP in seepage problem has not been resolved, and DOP carcinogenesis, has so far. Currently abroad, basic need not DOP, PVC plasticizer epoxidized soybean oil, citric acid and alcohol precipitation method is used in low and high security of the new type of plasticizer. New type of treatment, diagnosis, prevention, health care use plastic products market development prospect is also very bullish.
Medical plastics industry in China is facing great opportunities for development, at the same time, it must be positive and international competition and the challenge of weak foundation of themselves, medical plastics industry in China should make use of the information age brings convenient, timely grasp industry trends, improve the quality of the products, accelerate product upgrading, in ensuring that existing products on the basis of market share, increase the capacity for independent innovation, timely production, study and research, combined with industry technology innovation system, creating its own brand, and strive for an early into the world leading medical plastic products category.
