To push new innovations to truly benefit users. and the environment, it is very important to have partners with the same vision. As IRPC Public Company Limited or IRPC has been trusted by Lion Corporation Thailand Limited (“Lion”) in selecting the DURA – PRO product line of plastic from POLIMAXX® ,Brand under IRPC for use in Producing the latest innovative toothbrush from Japan ‘ Systema Slim TEQ ‘ . The toothbrush model is designed to have a thinner brush head and neck. Helps to deep clean the hard to reach parts of the mouth to thoroughly clean every nook and cranny. and improves the oral health of users.
Another thing that ‘Lion’ gives importance to is the selection of quality plastic resins that are suitable for production. Considering the specific performance standards of toothbrushes, reducing the thickness of the toothbrush head and neck is a new and challenging idea. This is because the plastic around the head of the toothbrush is 40 % thinner than the normal model, but it must be strong and durable for use. It also must support the various conditions of the toothbrush production process. Therefore, the plastic resins used must be strong enough to not break. When the bristles are inserted into the base of the toothbrush head during the manufacturing process.
Which in the first period ‘Lion’ has tested plastic resins from many sources, but no plastic resin from anywhere meet the performance that the team expects. Especially in terms of strength and durability of plastic resins. As a result, the quality of the toothbrush is not as good as expected. They are also concerned about the problem of brush head breakage during the production process and its durability for use by consumers.
But with the determination of IRPC In answering the needs of ‘ Lion ‘ , cooperation has occurred. between IRPC and Milliken & Company developed a special grade plastic resins in the DURA – PRO group of POLIMAXX® which uses the Hyperform ® property enhancer from Milliken and has become a plastic resins that meets the needs for the production of this type of toothbrush in Thailand by POLIMAXX® DURA – PRO. It is a PP Homo – polymer plastic that has high strength compared to similar grades of PP Homo – polymer . It is also able to withstand deformation when heated ( High heat stability ) , can produce large quantities in the same time period ( Fast cycle time ) , holds its shape well and does not distort easily ( Dimensional stability ) , and Plastic resins also have a good balance between shape and toughness. After initial testing in 2022 , Lion has chosen POLIMAXX® DURA – PRO plastic resins to exclusively produce its ‘ Systema Slim TEQ ‘ toothbrushes.
It can be seen that the use of POLIMAXX ‘s DURA – PRO plastic resins is a part that makes ‘ Lion ‘ able to operate according to its goals. Sustainability Helps reduce carbon dioxide emissions in the supply chain and manufacturing process ( Supply chain and manufacturing CO2 reduction ) , which is also in line with IRPC ‘s carbon dioxide emissions reduction policy.
