TENAC™ molding conditions

  1. Before handling or using any TENAC™ polyacetal resin, be sure to consult the relevant Material Safety Data Sheet (SDS), available Asahi Kasei Corporation. Polyacetal resins generate gases, principally formaldehyde, during decomposition.
  2. Keep away from flame and heat sources. During a fire, irritating and highly toxic gases (formaldehyde, carbon monoxide, etc.) may be generated by thermal decomposition or combustion.
  3. If resin is spilled on the floor, clean it up immediately to prevent slipping and falling.
  4. Their decomposition in the cylinder of the molding, extruding, or other processing machine may also cause a dangerous high-pressure buildup inside the cylinder. When handling or processing TENAC™, the following precautions must be observed.

    1. Avoid resin temperatures and cylinder residence times which may cause resin decomposition. The following limits are a general guide; temperature and residence time may be lower for specific operating conditions.

      – Resin temperature

      Optimum: 190 – 210°C
      Maximum: 230°C
      – Maximum cylinder residence time
      For non-reinforced non-colored resins:
      50 min. at 190°C
      40 min. at 200 °C
      30 min. at 210 °C
      For colored or reinforced resins, consult Asahi Kasei Corporation.
      (上記は一応の目安であるが諸条件により異なるものである。)

    2. In any case where the cylinder residence time exceeds the relevant limit, promptly purge the cylinder.
    3. At shutdown, purge all resin from the cylinder before turning off the cylinder heater.
    4. As purging material, use only non-colored polyethylene, transparent polystyrene, or Asaclean purging agent from Asahi Kasei; do not use any other resin. 
      Always submerge purged resin in water immediately after purging, to prevent air contamination in the working environment.
    5. Do not mix TENAC™ with pigments or additives other than those designated by Asahi Kasei, or with different resins or resin grades, as this may degrade the thermal stability of TENAC™ and lead to decomposition.
    6. Ensure that the cylinder, nozzle, hot runners, and other high temperature zones are free from local resin detention, as this may result in resin burning or decomposition. In the event of such detention, promptly remove all residual resin by complete, thorough purging.
    7. Always provide adequate local or general ventilation to maintain a safe working environment.
  5. The information provided here is accurate to the best of our knowledge, based on all information and data available at this time, and is subject to change without notice. It is provided with no guarantee or assumption of liability whatsoever. It applies only to the normal handling and use of TENAC™ as a molding material. Any other use or application would necessitate additional, special safety precautions, and is not recommended.

TENAC™-C molding conditions

  1. Before handling or using any TENAC™-C polyacetal resin, be sure to consult the relevant Material Safety Data Sheet (SDS), available Asahi Kasei Corporation. Polyacetal resins generate gases, principally formaldehyde, during decomposition.
  2. Keep away from flame and heat sources. During a fire, irritating and highly toxic gases (formaldehyde, carbon monoxide, etc.) may be generated by thermal decomposition or combustion.

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.
