Introduction
Mitsubishi Engineering-Plastics has developed a high-grade acetal copolymer using the Company's proprietary advanced technologies. lupital is a high-grade copolymer type of acetal resin made with a totally new process. Our integrated production system, which takes the raw material methanol through to the end product in pellet form, enables us to consistently manufacture and supply high-quality products.
To meet a wide range of customer requirements, lupital is produced in a variety of grades. These include high-performance grades, which make lupital ideal for applications in such fields as electronics, office automation equipment, automobiles and precision machinery.
Due to extensive technological know-how accumulated through long experience, Mitsubishi Engineering-Plastics is the top producer in this field. From applied processing technology for grade development to strict quality control technology, we have the capability to respond to an array of customer needs.

Features of lupital
lupital is a crystalline polymer with a molecular structure of
-[CH2-O]n-[CH2-CH2-O]m- and “C-C” bond-producing copolymer features.•Well-balanced mechanical properties and high fatigue resistance
•Excellent anticreep properties
•Excellent low friction and anti-wear properties
•Wide range of operating temperatures
•High oil and organic chemical resistance
•Excellent thermal stability in molding
The manufacturing process for lupital
2
Grades and Special Features
lupital is available in a variety of grades to suit many applications. The appropriate grade is selected in accordance with the function required for a given application.
lupital can be delivered as colored pellets for various applications.In addition, color concentrates (master batches) are available upon request.

Friction and Wear-Resistance Characteristics
Low friction and wear resistance are lupital's main characteristics, which make it ideal for sliding mechanical parts such as gears, bearings and pinch rollers.For applications requiring low friction or high wear resistance, special grades of lupital are recommended. The FX-11(J) grade is highly recommended for low-noise applications, such as gears.

Dimensional Stability
lupital has good dimensional stability after a long period of use. After the shrinkage of an injection molding is completed (approximately 2 days), lupital dimensions remain stable permanently. In addition, lupital's low water absorption makes dimensional changes extremely minimal. This means lupital is well suited for high precision parts such as gears and electronic devices.

Chemical Resistance
A major characteristic of lupital is its high chemical resistance. With the exception of strong acids such as hydrochloric acid and sulfuric acid, lupital has extremely high resistance to organic solvents, oils, grease and synthetic chemicals. lupital is therefore suitable for applications involving contact with chemicals and oils, including vehicle parts, pumps and lubricated gears.

Weather Resistance
Aside from long outdoor use or exposure to direct sunlight, lupital standard grades are suitable for applications involving exposure to light. For applications such as interior and exterior automobile parts and window parts exposed to sunlight, lupital weather-resistant grades are highly recommended.
