Plastic rubber has long been one of the important raw materials for medical equipment and pharmaceutical packaging
.
Among them, PEEK has strong corrosion resistance, hydrolysis resistance, chemical resistance, especially inertness to body fluids.
The pain caused by traditional puncture to patients; while medical-grade polycarbonate meets the advantages of biocompatibility, strong corrosion resistance and unbreakable, and is the first choice for capsule endoscope shell materials
.
The continuous development of medical plastics and processing technologies developed for the medical industry helps manufacturers of medical devices and disposable medical supplies improve production efficiency and product quality, respond to the growing market demand, and create unlimited business opportunities
.
Characteristics and applications of commonly used medical plastics
Characteristics and applications of commonly used medical plastics1.
Polyvinyl chloride (PVC)
Polyvinyl chloride (PVC)
At present, PVC accounts for 25% of medical plastic products in the market
.
2.
Polyethylene (PE)
Polyethylene (PE)
UHDPE has high impact strength, low friction, stress crack resistance and good energy absorption properties, making it an ideal material for artificial hip, knee and shoulder connectors
.
3.
Polypropylene (PP)
Polypropylene (PP)
Medical PP has high transparency, good barrier properties and radiation resistance, making it widely used in medical equipment and packaging industries
.
4.
Polystyrene (PS) and K resin
Polystyrene (PS) and K resin
PS is the third largest plastic variety after polyvinyl chloride and polyethylene.
It is usually processed and applied as a one-component plastic.
The main features are light weight, transparency, easy dyeing, and good molding performance
.
K resin is made by copolymerization of styrene and butadiene.
It is an amorphous polymer, transparent, odorless, non-toxic, with a density of about 1.
01g/cm3 (lower than that of PS and AS), and its impact resistance is higher than that of PS.
, good transparency (80-90%), thermal deformation temperature of 77 ° C, the amount of butadiene contained in the K material, the hardness is also different, because the K material has good fluidity and a wide processing temperature range, so its Good processing performance
.
These two materials are mainly used in pharmaceutical packaging supplies
.
5.
Acrylonitrile-butadiene-styrene copolymer (ABS)
Acrylonitrile-butadiene-styrene copolymer (ABS)
ABS has certain rigidity, hardness, impact and chemical resistance, radiation resistance and ethylene oxide sterilization resistance
.
ABS is mainly used in medical treatment as surgical tools, roller clips, plastic needles, tool boxes, diagnostic devices and hearing aid shells, especially the shells of some large medical equipment
.
6.
Polycarbonate (PC)
Polycarbonate (PC)
Typical properties of PC are toughness, strength, rigidity, and heat-resistant steam sterilization, which make PC the preferred choice for hemodialysis filters, surgical tool handles, and oxygen tanks (when in surgical heart surgery, this device removes blood carbon dioxide, increasing oxygen)
.
Medical applications of PC also include needle-free injection systems, perfusion instruments, blood centrifuge bowls and pistons
.
PC is also used in myopia glasses due to its high transparency
.
7.
Polytetrafluoroethylene (PTFE)
Polytetrafluoroethylene (PTFE)
PTFE has excellent performance, the friction coefficient is the lowest among plastics, and it has good biocompatibility.
It can be made into artificial blood vessels and other devices directly implanted into the human body
.
FCS (FCS) has accumulated more than 45 years of research and development energy and experience in plastic injection molding machines to meet customer needs for various products and stable production quality.
High-efficiency energy-saving and two-color injection molding machines have attracted much attention.
During the epidemic, many customers adopted FCS toggle-type precision energy-saving injection molding machine produces goggles products to protect against the epidemic!
FB-160R Multi-component injection molding machine
FB-160R Multi-component injection molding machineFCS has been leading the development direction of the industry with its advanced technical strength in the field of multi-component molding.
The maximum clamping force of the multi-component injection molding machine it has developed can reach 1900 tons
.
Equipped with closed-loop servo valve, new single-cylinder injection structure, and patented turntable positioning fixture and other technologies to achieve stable operation and precise positioning requirements.
FB-160R multi-component injection molding machine can automatically produce medical oxygen masks, which has won praise from many users multi-component molding technology
.
CT-120e all-electric injection molding machine
CT-120e all-electric injection molding machineThe CT-e series all-electric injection molding machines are the solution of choice for precision plastic parts
.
The injection speed can reach 300 mm/s, and the repeatability of the injection position can reach 0.
01 mm
.
It has the advantages of high injection precision, fast injection acceleration, and full closed-loop control that cannot be achieved by hydraulic servo.
It is not affected by oil pollution and temperature, and has good process stability
.
At the same time, it has the advantages of precision, stability, high efficiency, power saving and environmental protection
.
Therefore, it is very suitable for medical industry applications
.
