What is TENAC™ biomass certified grade?

Asahi Kasei's TENAC™ biomass certified grade POM resin has been certified with ISCC PLUS, an international certification system for sustainable products. This certification system employs a mass balance methodology that allocates the amount of biomass-derived products produced according to the ratio of biomass raw materials used when a product is manufactured using both biomass and petrochemical-derived raw materials.

TENAC™ biomass certified grade maintains the same performance standards as traditional fossil fuel-derived POM resins, while also achieving reductions in CFP (Carbon Footprint).

TENAC™ Biomass Certified Grade

Features of TENAC™ biomass certified grade

Maintains performance comparable to fossil fuel-derived POM resins

TENAC ™ biomass certified grade retains the same excellent properties as conventional fossil fuel-derived POM resins, including superior friction and wear characteristics, strength and rigidity, and resistance to oil and organic solvents. As a result, it can contribute to sustainability across a wide range of applications.

ISCC PLUS certification obtained through mass balance method

TENAC™ biomass certified grade has acquired the "ISCC PLUS certification," one of the international standards for sustainable products, by utilizing the "mass balance method."

ISCC logo

The mass balance method is a technique that allocates the production volume of biomass-derived products based on the proportion of biomass inputs used in the manufacturing process alongside fossil fuel-derived raw materials.
The ISCC PLUS certification is an international standard that ensures the production and use of biomass raw materials under this mass balance method. It mainly manages and guarantees the supply chain of bio-based and recycled materials sold globally.

Significant reduction in CFP compared to fossil fuel-derived POM resins

Tenac™ biomass certified grade can reduce the CFP (Carbon Footprint) by up to approximately 50% compared to conventional fossil fuel-derived grades.

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

We have prepared a separate "Product Safety Data Sheet" regarding precautions for handling TENAC™, so please read it before using TENAC™. The following points are important points when handling TENAC™. Please use it for safe handling of TENAC™. Please investigate the safety of pigments, additives, etc. that your company uses other than those specified by Asahi Kasei TENAC™ and their compatibility with 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.
