TENAC™-C (ZM413 grade)

Low emission (formaldehyde) gas, Environmentally friendly, metallic-colored polyacetal resin

Asahi Kasei has modified the conventional polyacetal resin to take on metallic colors while achieving low VOC emission. This contributes to significant cost reduction by eliminating plating and coating process as well as reducing nagative impact on the environment. The resin also has weather resistant property.

QWhich interior parts use ZM413?

A It is used not only for interior decoration parts that require designability, but also functional parts that require durability such as inner door handles.

QCan ZM413 be used instead of a plated product?

A Although it is difficult to reproduce the same exact metallic feel of plated products, but ZM413 can be a lighter option to such product while maintaining equivalent durability.

QCan it also be used for exterior parts?

A No, it does not meet the weatherability standard required for exterior parts.

QCan we use mold for existing products to process ZM413?

A The orientation of aluminum pigment becomes uneven, causing material-specific appearance defects. In order to suppress appearance defects, the product shape and the gate position must be optimized.

QWhat molding conditions do you recommend?

A ZM413 can be molded under the molding conditions that are the same as those for normal polyacetal resin. However, even when the same coloring method is applied, the design (appearance) of the molded product may change depending on the mold temperature or filling speed.

QHow do we adjust colors?

A Normally, you should adjust colors by referring to color plates (painting samples, etc.). The visual image may differ depending on whether the object is a solid body or a curved or flat object. Thus, it is necessary to check the color of molded product and adjust accordingly.

ZM413's low VOC emission and good weather resistance properties makes it suitable for use in vehicle interior parts. The metallic color often contributes to sophisticated designs.

Feature01

Excellent design capability

Asahi Kasei offers wide range of colors in various levels of brightness and shades of glossiness.

Feature02

Low VOC emission

Even though ZM413 is metallic-colored, it maintains low VOC emission (VDA275 < 2 ppm), and its physical properties as well as weather resistance are equivalent to those of engineering plastics of general weather resistance grade.

Feature03

Cost reduction and environmental load

Generally, to produce a metallic part, the surface of its base resin is coated. Coating require multiple processes and are thus costly. In addition, since solvents are used in some processes, negative environmental impact is expected. These are the drawbacks of coating. The use of Asahi Kasei's ZM413 can eliminate the coating processes. Thus, making ZM413 an envrironmentally friendly choice.

Usage example01

Vehicle interior parts

ZM413 contributes to safer and more luxurious interior designs. Surface of coated products often starts to peel due to wear over time exposing sharp edges that may lead to injuries when in contact with human skin. Since ZM413 eliminates the coating process it reduces such risk to zero. This property also works in favor to keep the interior design of the vehicle fresh and maintains the luxurious in-vehicle atmosphere.
