Medical grade plastic are widely used for medical devices, due to excellent wear resistance, high temperature resistant and chemical resistance, biocompatible and good safety, etc, which is usually designed and manufactured into various-structure medical plastic parts for medical device assembly by medical plastic injection molding.
Medical Plastic prodcts can be produced by medical plastic injection molding, extrusion molding, film blowing machine, foaming moulding ,and so on.
Medical Plastic Injection Molding processing prosedure: Under a certain working temperature as required, Stirring the melting plastic material by screw and then shot the melting plastic into mold cavity by high pressure. After cooling, we can get the finished medical plastic parts.
Plastic used in medical devices has lower cost, which can not be disinfected and reused, and medical grade plastic is suitable for use as disposable medical equipment.
Adding heat stabilizers, anti-aging agent, anti-UV agents, plasticizers in resin can improve the plastic defects, after granulation modification, increasing mobility, to produce a variety of processing technology, special Performance and different grades of plastic varieties.
Medical Plastic mainly includs PVC,PE, PP, PS, PC, ABS, PTFE,etc.
Medical Plastic Material Feature
(1)Good chemical resistance
(2)Shiny, partially transparent or translucent
(3)Mostly good insulators
(4)Light weight and sturdy
(5)Easy processing and mass production, lower cost
(6)Wide range of uses, utility, easy to color, resistance to high temperature
|Medical Plastic Advantage||Medical Plastic Disadvantage|
|1. Excellent anti-corrosion||1.Classification is very difficult when recycling plastic waste|
|2. Lower production cost||2.Easy to burn to produce toxic gases.|
|3. Durable, waterproof and lightweight||3.Limited resources|
|4. Easily molded into different shapes||4.Not perishable|
|5. Good insulator||5.Poor heat resistance and easy to aging|
|6. can be used to prepare fuel oil and fuel gas, which can reduce crude oil consumption.||6.Not naturally degradable|
