# Purified terephthalic acid: Relationships

Source page: https://www.materialinsights.org/chemicals/pta/links/

Every element and industry that Purified terephthalic acid is linked to, and how. Each pair has its own card explaining the relationships between the two.

- [Polyester fibre](https://www.materialinsights.org/links/polyester-fibre-and-purified-terephthalic-acid/): PTA is the larger of the two building blocks of polyester, so polyester yarn and fibre makers live on a thin spread over PTA and MEG; in India, Reliance sits on both sides and trade rules on PTA decide how much cheap Chinese supply reaches spinners. *(researched)*
- [Monoethylene glycol](https://www.materialinsights.org/links/monoethylene-glycol-and-purified-terephthalic-acid/): MEG and PTA are the two halves of every polyester and PET molecule, bought together by the same plants in a fixed ratio. Both chains are centred on China, where capacity has outrun demand, so their margins have been squeezed at the same time even while polyester plants ran hard. *(researched)*
- [PET resin](https://www.materialinsights.org/links/pet-resin-and-purified-terephthalic-acid/): PTA is one of PET's two building blocks, joined with MEG and then solid-stated into bottle resin, so PET bottles are a direct, steady outlet for PTA. India now protects bottle-grade PET with a $200.66 a tonne duty on Chinese resin while buying more Chinese PTA, which tends to support domestic resin makers' margins. *(researched)*
- [Crude oil](https://www.materialinsights.org/links/crude-oil-and-purified-terephthalic-acid/): Crude oil is a raw material for purified terephthalic acid; their prices have moved together.
- [Acetic acid](https://www.materialinsights.org/links/acetic-acid-and-purified-terephthalic-acid/): Their prices have moved together.
- [Paraxylene](https://www.materialinsights.org/links/paraxylene-and-purified-terephthalic-acid/): Their prices have moved together.
- [Plastic and rubber products](https://www.materialinsights.org/links/plastic-and-rubber-products-and-purified-terephthalic-acid/): Plastic and rubber products depends on purified terephthalic acid.
- [Refining and reforming](https://www.materialinsights.org/links/purified-terephthalic-acid-and-refining-and-reforming/): Their prices have moved together.
- [Textiles and leather](https://www.materialinsights.org/links/purified-terephthalic-acid-and-textiles-and-leather/): Textiles and leather depends on purified terephthalic acid.
