Epichlorohydrin Rubbers

The effect of different technologies for the introduction of a plasticizer - dioctyl sebacate on the properties of rubbers based on epichlorohydrin rubber of the Hydrin T-6000 brand was investigated. When using the technology of rubber swelling in a plasticizer, dioctyl sebacate exhibits a shielding effect, reducing the interaction of the filler-polymer, which leads to an improvement in low-temperature properties and a deterioration in the physical and mechanical properties of the material.

In this paper, cashmere knitwear is dyed at a lower temperature compared to conventional dyeing, and its physical and mechanical properties are analyzed and compared. The results show that cashmere knitwear dyed at low temperature can improve cashmere knitwear quality. It is also shown that cashmere knitwear dyed at low temperature can have improved physical and mechanical properties, especially its strength, abrasion resistance and pilling resistance.

Zirconia Content

Physical and mechanical properties as well as microstructure of zirconia toughened alumina ceramics with different zirconia content were tested. The results show that the best physical and mechanical properties are obtained in sub-micron composite ceramic when zirconia content is 25%; while the physical and mechanical properties of nano-zirconia toughened alumina ceramics are far better than those of sub-micron zirconia toughened alumina ceramics. Therefore physical and mechanical properties of ceramics can be improved significantly by adding proper amount of zirconia into alumina matrix and refining zirconia particles.

Copolyarylates based on a mixture of 2,2-bis (4'-hydroxyphenyl) propane, 3,3-bis (4'-hydroxyphenyl) phthalide, terephthalic and isophthalic acid chlorides and 3,5-dibromo-p-hydroxybenzoic acid chloride were synthesized by low-temperature acceptor-catalytic polycondensation. To study the structure of the obtained polyesters and study the physical and mechanical properties, infrared spectroscopy, elemental, thermogravimetric, X-ray structural and thermomechanical analyzes were used. The obtained polymers have high values ​​of strength characteristics, thermal and heat resistance, good fire resistance.
