What is TENAC™-C FF520?

In PIM technology, polyacetal (POM) is used as a resin constituting a binder due to the high strength of POM itself as well as the advantage that it is decomposed without residue by acid and heat.

​TENAC™-C FF520 is a POM copolymer that provides very high fluidity while maintaining the excellent mechanical properties of POM.

TENAC™-C FF520 characteristics

Excellent Flowability

As shown in the table below, TENAC™-C FF520 exhibits higher flowability compared to our conventional high-flow grade product. It’s available for your complicated and thin shapes.

Comparison of TENAC™-C FF520 properties vs. reference values for other resins used as PIM binders.
General Physical Properties

Excellent Flowability

Decomposability

POM undergoes depolymerization due to thermal decomposition and there is no residue.
Molded products using TENAC™-C FF520  can be degreased and sintered to obtain densely sintered products without cracking or blistering.

Application Cases

Powder injection molding

×

Powder Injection Molding (PIM) is a method of manufacturing small, high-precision metal and ceramic parts by injection molding metal or ceramic powder.
Specifically, metal or ceramic powder and binder are mixed and pelletized into feedstock, which is then injection molded.

Product Data/Tips for Use *Handling Precautions

Precautions for handling TENAC™

The content of this document is based on currently available materials, information and data, and may be revised based on new findings. Please note that these are provided as information and are not guaranteed. Therefore, when using our products, please give full consideration to the usage environment, design, etc., and use them at your own risk after judging that there is no problem with the product.

1. Handling Precautions

Please read the separate "Material Safety Data Sheet" for handling precautions for TENAC™ before using TENAC™. The following points are the main points for handling TENAC™. Please use it for safe handling of TENAC™. Please investigate the safety and compatibility with TENAC™ ™ of pigments, additives, etc. that you use other than those specified by Asahi Kasei TENAC™.

(1) Safety and health precautions
The main component of the gas generated when TENAC™ is dried, melted, and decomposed is formaldehyde. Take care to avoid contact with eyes, skin, and inhalation. Also, avoid touching the high temperature resin directly. For each work such as drying and melting, it is necessary to install a local exhaust system and wear protective equipment (safety glasses, protective gloves, etc.).

(2) Precautions regarding combustion
TENAC™ is flammable and should be handled and stored away from heat and sources of ignition. If it burns, it may generate toxic gas. Water, foam, and dry powder can be used to extinguish the fire.

(3) Precautions for disposal
TENAC™ can be disposed of by landfill or incineration, but please entrust it to an authorized industrial waste disposal company or local government in accordance with the "Waste Disposal and Public Cleansing Act." In addition, when incinerating it yourself, please use incineration equipment and process in accordance with various laws and regulations such as the Air Pollution Control Act. When incinerated, toxic gas may be generated.

(4) Notes on storage
It is a combustible material (synthetic resins) designated by the Fire Service Act, and should be handled in accordance with municipal ordinances. (fire extinguishing equipment, indoor storage facilities, etc.)

(5) Notes on molding
Please pay attention to the following points to avoid decomposition of the resin.・Do not allow the resin to remain in the processing machine for a long time at high temperatures.・Do not mix extrusion with strong acids, oxidizing agents, or PVC. Pellets, etc. spilled on the floor may slip under your feet and cause a fall if left unattended, so please clean and remove them immediately.

2. Usage

  • ・Do not use TENAC™ for implantation into the body or for direct contact with body fluids or infusions. When using this product for other medical purposes, please be sure to contact our representative in advance.
  • ・When using TENAC™ in applications where it comes into direct contact with food, please select a grade that complies with the Polyhyeikyo PL (Positive List), Food Sanitation Law, and FDA. In that case, please be sure to contact our representative in advance.
  • ・When using TENAC™, be sure to evaluate the physical properties, durability etc. of the actual product in advance.
