With so many polypropylene grades of medical and Lab Consumables, which one is the new favorite in the medical industry?
Medical and laboratory materials have become one of the development directions of polypropylene. In this field, imported materials also account for a considerable proportion.
Medical and laboratory consumables PP
PP plastic has higher transparency, better barrier properties and radiation resistance, making it widely used in medical equipment and packaging industries.
The characteristics of medical and laboratory consumable plastics
PP plastic is colorless, tasteless and non-toxic. It is a kind of thermoplastic with excellent performance. It has the advantages of small specific gravity (0.9g/cm3), non-toxicity, easy processing, impact resistance, flexural resistance and so on.
The main properties of PP plastics for medical and Lab Consumables
disinfect
PP plastic is a semi-crystalline material with high melting point and good heat resistance. The yield strength, tensile strength, compressive strength, hardness and elasticity are higher than those of polyethylene (PE). In addition, it must have anti-gamma ray sterilization performance.
In short, it is resistant to high heat and pressure, radiation resistance, non-toxic, corrosion resistance, good insulation and easy processing.
Low temperature resistance, impact resistance
Homo-PP is more brittle, and random copolymer PP synthesized with ethylene has better toughness and stronger impact strength. For products usually used under low temperature conditions, it is necessary to use copolymer PP as much as possible, or add thermoplastic rubber to modify PP to increase its flexibility and low temperature impact resistance.
Domestic medical and laboratory consumables polypropylene materials are mainly used in disposable medical equipment, such as disposable syringes, blood transfusions, infusion tubes, etc., while abroad has been widely used in packaging materials, laboratory appliances, high-end medical equipment and other fields.
The sanitary performance index of ordinary PP cannot meet the standards for producing medical products, and its transparency (optical effect) is poor, which limits its application.
Therefore, in recent years, domestic enterprises have increased the development of medical polypropylene products.
For example, Yuntianhua RM023T, Shenbo Technology SP2500M, Sino-Korea GA260R and Lotte J-560M have performed extremely well in recent medical and laboratory consumables. So which one is the new favorite of the medical industry?
The following general performance comparison

＞Shenbo Technology SP2500M (12%)
＞LOTTE J-560M (20%)
Impact strength (kg/m)
Shenbo Technology SP2500M (7.5kJ/m)
＞China and South Korea GA260R (5.8kJ/m)
＞LOTTE J-560M (5.5kJ/m)
＞Yuntianhua RM023T (4.5kkJ/m)
Flexural modulus (Mpa)
Shenbo Technology SP2500M (1650Mpa)
＞LOTTE J-560M (1180Mpa)
＞Yuntianhua RM023T (970Mpa)
＞China and South Korea GA260R (964Mpa)
Shenbo Technology SP2500M, Lotte J-560M, China and South Korea GA260R have anti-gamma ray sterilization properties. The above polypropylene resin has high transparency, good stiffness/impact strength balance, high gloss, and low odor.
*The medical and laboratory consumables produced by the above four brands are as follows:
China is the world's largest producer of medical syringes, with an annual output of approximately 17 billion syringes, accounting for 70% of the world's total output. The annual export ratio of syringes is about 40%, and the annual growth rate of the domestic market is about 8%.
The above four grades can be used in the production of syringes, and the transparency and toughness are also quite good. Of course, the medical reports are also complete.
Starting in 2020, domestic technical reserves and production preparations for nucleic acid testing sampling tubes and deep well plates have been carried out. At the same time, due to the impact of the new crown epidemic, the demand for nucleic acid testing has increased significantly, and the market has gradually expanded.
This product will be greatly improved this year in 2021.
The flexural modulus performance of the above four models is very outstanding, which can fully meet the production requirements of deep hole plates.
Since the epidemic, various companies have contributed to the fight against the epidemic, especially in the medical device industry, where virus detection products have continued to expand production and improve technology. Efficient, fast, low-risk, and low-cost virus sampling products are urgently needed in the current market.
The small size carries a big dream, a cell and biological tissue that preserves countless hopes for life and health. It is the cryostat. The cryopreservation tube products used to store samples of cells, biological tissues, etc., can be deep-frozen for a long time.
Different grades have different performances, and they are all born according to the standards of different industries. Specifically, the product is used as the production benchmark, and the production of each product has a different corresponding and suitable brand.
In addition to the production of medical and laboratory consumables, the above four models are also widely used in the production of daily chemicals, medical equipment, industrial parts, chemical containers, etc., as well as food and pharmaceutical packaging.
