Material properties of mica sheets and precision pressing processing know-how _ Technical documentation
An insulating material with high heat resistance, flame retardancy, and corrosion resistance, which is also expected to prevent the spread of fire in lithium-ion batteries. Documentation explaining its characteristics and processing methods is currently available.
The difficulty of processing "mica sheets" is accompanied by challenges such as interlayer delamination, burrs, and dust generation. Addressing these issues requires expertise in "molds" and "handling methods for mica sheets." At our company, Yamada Manufacturing Co., Ltd., we have accumulated years of experience in processing mica sheets and possess extensive know-how. This document, "Technical Data: Mica (Muscovite) Material Properties & Processing Know-How," summarizes these insights and experiences in an easily understandable manner from our perspective. [Contents (partial)] ■ What are mica sheets / MICA / Muscovite? ■ Material properties ■ Examples of products used ■ Points to be careful about during processing, handling precautions ■ Solutions to issues at our company ⇒ You can view the document immediately from [PDF Download]. Please use it when considering material selection and processing vendors!

Company information
Yamada Manufacturing is a leading company in non-metallic resin pressing, primarily focusing on the processing of Bakelite, and we deliver a wide range of products such as resin press parts and insulating parts to the automotive industry. Bakelite processing utilizes a variety of materials, including paper and fabric substrates, as well as our mainstay glass substrates. Our products are increasingly being adopted in automotive electrical components, electronic device parts, and more recently, in electric vehicle components, which has garnered us further patronage. Additionally, we have a proven track record in processing a diverse array of materials, including thin film products, melamine, and rubber. In recent years, we have also achieved cost reductions through shape processing of adhesive-backed materials and by applying adhesives to substrates in-house before shape processing.
