The difference between metal and plastic in ureter
Reinforced nylonThe incorporation of various fibrous materials into polyamides
Aromatic nylonThe benzene ring structure is introduced into the main chain, which has high temperature resistance, radiation resistance and corrosion resistance
Monomer casting nylonFeatures: 1 high molecular weight, simple technology, products of various shapesIt can produce large mechanical components the low water absorption rate
Amorphous transparent nylonHigh light transmittance and good dimensional stabilityA new variety of PA plasticsAdvantages: the plastic has good physical and mechanical properties, chemical stabilityThe polymer rich source, low priceThe modified plastic is easy to get good biocompatibilityThe plastic processing is convenient, easy moldingDisadvantages: the first medical plastic polymer residues are strictly limitedThere is a variety of metal ions in the production processThe medical plastic resin requirements of high purity, narrow molecular weight distributionThe long-term use of additives to the precipitationIt requires some special properties of plastics
