The Asahi Kasei TENAC™ Grades
TENAC™ is the brand name of Asahi Kasei’s polyacetal (POM) product group. The TENAC™ grades are characterized by superior mechanical properties, above all, their dimensional stability, as well as excellent chemical resistance, ease of molding and extremely low emissions. They are used in a large number of applications – including especially interior fittings in the automotive sector.
Asahi Kasei is not only the sole POM manufacturer in the world to produces both Homo and Co-polymer, we successfully combined the positive properties of both qualities in one product, resulting in so the called “HC grades”, available in several viscosity grades.
Our broad TENAC™ product range also includes eco-friendly grades like the low emission TENAC™ Z series.
Key Features of TENAC™ Homo-polymer
Due to its low-friction and high-wear properties combined with high strength and stiffness, TENAC™ homo-polymer is an ideal alternative for metal parts offering excellent dimensional stability. It combines high tensile strength, stiffness, creep and fatigue resistance, and significantly higher impact resistance making it possible to produce lighter parts in shorter production cycles contributing in reduction of production costs and environmental load.
Excellent Dimensional Stability
Excellent Creep and Fatigue Resistance
High Stiffness and Strength
Easy Processing Enabling Thinner and Lighter Parts
Outstanding low-Friction Properties
Key Features of TENAC™-C Co-Polymer
In comparison with homo-polymers co-polymers provide a higher stability to heat and oxidative degradation. Therefore, they are often used in applications centered on mechanical components and critical parts demanding excellent chemical resistance.
Excellent Dimensional Stability
Outstanding Low-Friction Properties
Excellent Resistance to Creep, Fatigue and Chemicals
Low Water Absorption
TENAC™ Low-Emissions Grades
The in-cabin air quality is becoming increasingly important. With the increased use of plastics inside the car, the reduction of VOCs (volatile organic compounds) is becoming a key factor for an improved in-car air quality. TENAC™ can contribute to passenger safety and comfort trough improved cabin air quality by reducing VOC emissions (VOC value of < 2 ppm).
