“…In this regard, it is important to note the need to control the level of absorbed doses during sterilization of medical products made of nonwoven materials based on polypropylene, as well as to control the strength of the materials of products after sterilization. The slightest changes in the composition of raw materials, for example, a decrease in the content of a complex of stabilizing additives used to stabilize polypropylene [29][30][31][32], from which the nonwoven material is obtained, as well as changes in the technological process of obtaining the nonwoven material itself (for example, a decrease in the surface density by 1-2 g/m 2 ) can lead to a significant loss of strength of the material.…”

Radiation sterilization is widely used to sterilize nonwoven SMS medical products. SMS materials have improved filtering and barrier properties, low bacteriopermeability and, due to these properties, are indispensable for medicine. They are used to make such important health care products as disposable surgical clothing and underwear. As a result of the research carried out, the effect of gamma and electron radiation, in the range of absorbed doses from 15 to 25 kGy, on the strength characteristics of nonwoven SMS materials based on polypropylene with a surface density of 35, 40, 50 g/cm2 was studied. It has been established that the strength characteristics (tensile strength, tensile strength, and tear strength) of nonwoven materials decrease after exposure to ionizing radiation. The higher the density of the material, the more its characteristics decrease after radiation sterilization. It was also found that gamma radiation, due to its nature, has a stronger effect on nonwoven materials based on polypropylene, and leads to a stronger decrease in strength characteristics. In general, for products sterilized by ionizing radiation and made from SMS materials, it is important to control the strength characteristics, primarily, the tensile strength in the transverse direction of the web stuff.

“…Это связано с наличием в его составе большего количества ненасыщенных жирных кислот. Действительно, литературные данные указывают на большее биоразложение соединений с двойными связями в молекуле [17,18]. При этом использование в качестве модифицирующей добавки эпоксидированного соевого масла обуславливает увеличение выделения углекислого газа в 2,6 раза, что коррелирует с данными, представленными на рис.…”

Polymer-based sealing materials currently play a large and important role in almost all areas of industry. The use of sealants can increase the energy saving of building structures, the safety of vehicles, etc. Sealants are equally used in such specialized applications as the aerospace field, and are also used to solve everyday problems, such as sealing plumbing. The main consumption of sealants is in construction and automotive. This review provides data on the global and domestic market for sealing materials; The basic terms and definitions used in the field of adhesive and sealing materials are analyzed. The main differences between the terms adhesive and sealant are discussed. The classification of sealants is given in accordance with modern international regulatory documents. It is disassembled that they are one-component reactive hot-melt sealants. Their main advantages and disadvantages are listed. It is noted that the development of the industry of sealing materials is likely to move towards the development of moisture-curing compositions based on silane-modified polymers. This assumption is supported by a fairly detailed classification of silane-modified polymers in the FEICA classification guide for sealants and adhesives.
