We have been made lots of PPSU medical plastic parts, and we have been made full version of LSG PPSU ( Life Science Grade ) plastic molding parts ( over 40 version of PPSU LSG injection molding parts), if you need PPSU LSG injection molding parts for your medical using please contact with us, we can offer you some samples for you to test,
PPSU plastic is for medical injection molding products, and has the highest performing thermoplastic that gives better durability and heat tolerance, PPSU material has better impact strength and chemical resistance than PSU and PES. Due to its a high melting point of 208°C, PPSU plastics are commonly used in aerospace and medical devices that require repeat sterilization. PPSU milk bottles are significantly more expensive than PP and PES milk bottles, but if you are willing to spend on milk bottles that your baby uses up to 6 times per day, this makes for a worthy investment. Despite its supreme durability, it is advisable to change your PPSU milk bottles yearly.
PPSU plastics Key Properties
- Outstanding toughness and impact resistance
- High resistance to steam autoclaving
- Good chemical resistance
- FDA compliant
- High operating temperature (up to 160°C)
- High rigidity over a wide range of temperatures
- High dimensional stability
- Very good resistance against high energy radiation (gamma and X-rays)
- Good electrical insulating properties
The other medial plastic parts made from PPSU is artificial knee joint components, it is plastic spacer which used PPSU, and called PPSU LSG ( Life Science Grade ) , LSG PPSU ( Life Science Grade ) is used in the medical field, due the PPSU property, it is great plastics for artificial knee joint components.
PPSU offers superior hydrolysis resistance when compared to other amorphous thermoplastics as measured by steam autoclaving cycles to failure. Its virtually unlimited steam sterilizability makes it an excellent choice for medical devices.
PPSU injection molding
How to make PPSU plastic mold and PPSU injection molding parts
To make PPSU plastic molds and molding parts is not easy, here is some suggestion for your reference,
To make good quality PPSU plastic mold your need to choice the steel very carefully, the injection molding process is very important as well, since the mold temperature is about 200 °C during production, to make the good cooling systems in the mold is key point to insure that we could get good surface, hot to get the mold temperature up to 200 °C is things that we need to think about this as well, since the mold is already running with very high temperature, the mold life will be affected.
The flow rate of PPSU is not as good as other plastics, gate design is most important thing that we need to think about, for the type of special plastics we should be equipped special screw and nozzle in the injection machine, and some other special cooling controller systems.
