Description
Technical field
The present invention relates to medical material tech field more particularly to a kind of preparation methods of medical non-toxic plastic.
Background technology
Ethylene bis stearamide（Vinyl bis-stearamides）One hard and crisp white high melting-point wax, industrial goods are in slightly
The fine particle of yellow, it is nontoxic, it is without side-effects to human body, most of solvents are not dissolved under room temperature, and soda acid and aqueous medium are stablized,
The chlorinated hydrocarbons and aromatic hydrocarbon solvent of heat can be dissolved in, powder soapy feeling is stronger, and 80 DEG C or more to water with wettable
Compound.
There is good compatibility between this kind of material and intravenous fluid and blood, thus is widely used, it is such as each
Kind flexible pipe for medical purpose, blood storage device, dialysis attachment, surgical glove, medical condition and man-made organ etc..
Oral administration solid and liquid, medicinal plastic bottle belong to a kind of packaging material.Not cleaned and sterilizing can be used to Key works Drug packing, because
This, has higher requirements to microbial limit, and production environment and production process should meet the requirement of relevant laws and regulations.
