THE USE OF LOW MOLECULAR WEIGHT POLYETHYLENE TO OBTAIN PLASTERS

Abstract

Plasters of various types are widely used in life and work of various medical organizations In their production various excipients as adhesive materials or means of fixing of the main material of the carrier are used. Due to the fact that main excipients in the composition of plasters are substances of foreign production, it is rather urgent to replace them by substances of domestic production.The objective of the research is to study the possibilities of use of low-molecular polyethylene (LMPE) as the main component in plaster production.When determining an appropriate structure of a plaster on the basis of low-molecular polyethylene we studied various struc-tures of plaster masses and influence of various excipients on physical, chemical and technological qualities of the plasters received on their basis (resistance to flaking, the amount of plaster weight in a plaster, vapor permeability, water penetration of the fixing layer). It is established that LMPE in a certain combination with excipients can be used as the main substance for obtaining plaster weight meeting the requirements of General monograph "Medical plaster" of GF XIII edition. An appropriate ratio of LMPE with polyethyleneglycol is 400 - 60:40.
