Aluminum-catalyzed PET resin

New materials to promote PET recycling
Iwatani began selling aluminum-catalyzed PET with good recycling characteristics in the Japanese market in 2016. Indorama Ventures PCL, the world's largest PET resin manufacturer, introduced aluminum-catalyzed PET resin polymerization technology (licensed) from Toyobo Corporation and started production.
■Commodity features
Excellent reusability (high IV retention rate, low color tone change)
Since aluminum-catalyzed PET has high thermal stability during melting, it is less likely to undergo changes in color tone and physical properties caused by heat treatment during recycling, and it is considered to be a material suitable for promoting recycling.
In the experiment of nitrogen replacement and heat treatment at 300 ° C × 2 h, it is found that aluminum-catalyzed PET has almost no heat degradation and can maintain transparency.
Conventional PET products are mainly used for sheets and fiber, and the number of recyclables is also limited due to thermal degradation.
In contrast, aluminum-catalyzed PET is suitable for bottle recycling of cool drinks because of high thermal stability and transparency, and can realize the direct reuse of the bottle to the bottle. In addition, even if it is reused repeatedly, it is not easy to undergo thermal degradation, so it can be reused more times than previous products and it can promote the effective utilization of resources.
Environmental adaptability
Aluminum is one of the materials that have less impact on the environment. With the increasing attention to environmental problems, the sustainable supply of raw materials is realized by using aluminum catalysts with little load on the environment and human body.
Reduce contamination of the mold and production line by reducing the low polymer
Aluminum catalysts do not produce low polymers during melt, which can not only improve the transparency of the molded product, but also reduce the adhesion of the low polymer on the production line. Improve production efficiency by reducing the cleaning frequency of the production line.

Biomass PET resin

By using biomass MEG purified from bagasse as raw material, about 30% of the PET resin consists of plant source.
In the process from the manufacture of biomass MEG to product treatment, it can reduce the overall greenhouse gas by about 20% compared with PET from petrochemical.


Examples for usage

Beverage bottle

Cosmetic container

Soft film


■Commodity features
Reduce greenhouse gas emissions by about 20%
To promote the expansion of sales of sustainable raw material, Iwatani has conducted investigation based on the LCA (Life Cycle Assessment) that quantitatively evaluates the impact on the ecosystem and the environment from the beginning of the development stage. In 2011, DNP, Tokyo City University and the company jointly studied and surveyed, compared with petrochemical derivative PET manufactured from biomass MEG / biomass PET to product treatment, and found that the greenhouse gas could be reduced by about 20% (1.3 kg per kg of product).



In terms of processing
The company will directly cooperate with steel manufacturers from all over the world, and work closely with the metal processing base of the Iwatani Group in East China and South China and unique partner manufacturers to meet the needs of users in automobiles, batteries, electronic equipment, and high-precision and high-performance in mobile industries.
