Structure and properties of composites compression-molded from silk fibroin powder and waterborne polyurethane The degummed silk filament was pulverized with a home-made machine to obtain the silk fibroin (SF) powder with the diameter of around 3m. The resulting SF ... Yongzhen,Tao,Weilin,... ...
Polyurethane potting compounds are specially formulated by developers to meet a diverse range of physical, thermal and electrical properties. They can protect electronics by providing excellent dielectric and adhesive properties, as well as exceptional solvent, water and extreme temperature...
PURPOSE: To perform accurate leveling of an interior member and fixation easily without making adjustment of the underlay even though there is surface unevenness on a concrete structure to a certain degree, prevent generation of stains, fungi, etc., due to moisture, and accomplish a lightweight ...
The large range of uses, from 2K formulations to cast urethanes or PU dispersions is something very valuable as well since it is a real pain reliever when adapting the formulation to the end customer's needs." "This paper highlights the possibilities of bio-based polyurethanes, especially those...
Depending on the starting materials, the final product will have different types, properties, and uses. They have only the same urethane groups and the other parts of their chemical structure are completely different, so the form, structure, and, above all, properties of polyurethanes differ from...
Table 1. Summary of the polyurethane specimens with related properties. 3.2. Impact Tests Cylindrical specimens with 4.5 cm in diameter and 10 cm in height are placed on the support structure shown in Figure 3, where they are bound with a ring. The impact test is performed by applying ...
PU elastomer has characteristics similar to that of rubber. The properties offered by these elastomers include high elasticity, abrasion resistance, tear resistance, and chemical resistance. These properties make it suitable for footwear, construction application, wheels & tires, and machinery. The demand...
