We will provide a detailed explanation of the elements of combustion, the flame retardancy of plastics, and flame-retardant materials made from plastics.
Flame retardancy refers to the property of being difficult to ignite, primarily when plastics are directly exposed to flames, indicating their resistance to combustion. Plastics are widely used in products such as electrical appliances, automotive parts, and medical components. Flame retardancy is one of the very important evaluation criteria for ensuring the safety of these products. The flame retardancy grades of plastics are evaluated in six levels according to the UL94 standard, listed from lowest to highest as HB, V-2, V-1, V-0, 5V-B, and 5V-A. HB indicates that the material is slow-burning and does not have self-extinguishing properties. Grades V-2 and above have self-extinguishing properties, and the classification is based on combustion time. Fluoropolymer (PTFE) is cited as the material with the highest flame retardancy. These materials do not contain hydrogen atoms in their molecular structure, and the C-F bonds within the molecular structure are strong, making them difficult to ignite. Flame retardancy is an important indicator for enhancing the safety of plastics. It is crucial to select materials with appropriate flame retardancy grades according to the product's application and usage environment.

basic information
Fluororesin coatings are functional coatings that possess excellent properties such as: - Non-stick - Water and oil repellency - Heat and cold resistance - Low friction - Chemical resistance - Electrical properties Yoshida SKT has been engaged in fluororesin coating since 1963. In 1968, we signed a licensing agreement with DuPont in the United States. Among industrial fluororesin coatings, only manufacturers certified by Chemours (formerly DuPont) are allowed to process coatings under the name "Teflon (TM)." At Yoshida SKT, we provide coatings that maximize the properties of fluororesin tailored to our customers' needs. We respond flexibly from single items to mass production. Whether it’s mass-produced items or even a single part of a machine that exists only in one factory, we propose processing that suits the application and usage environment. We can handle everything from fine precision parts to large tanks. We can process a variety of items, from precision components active in cutting-edge fields to tanks with a depth of 6 meters, using our in-house equipment.
