The chemical structures of PET and PBT are basically very similar. Polyester is synthesized from an organic acid (here, terephthalic acid) and an alcohol. For PBT, its alcohol monomer becomes butanediol, while PET is ethylene glycol. The polymers thus obtained are well known - PBT and PET.

According to statistics, in 2021, the total consumption of nylon 6 chips in China will reach 4.127 million tons, and the consumption of nylon 66 will be about 640,000 tons.

Based on recycled PET material, the rPET honeycomb core is made from 100% recycled material, primarily from non-food post-consumer and industrial PET waste streams, helping to overcome the oversupply of these most problematic PET waste streams.
