Yantai, Shandong – Wanhua plans to build 30kT/year TPU facility at Wanhua Industrial Park in Yantai, Shandong province, adding the site’s total TPU capacity to 90kT/year.
Wanhua to expand Yantai TPU capacity
The project, pending regulatory approval, has CNY 154m ($24m) investment earmarked and includes six TPU lines. It also includes seven polyol lines, said Wanhua’s environmental filing.
The new thermoplastic polyurethane lines will use the continuous extrusion process and the polyol lines will use the batch process. These are same as the existing facilities, said the filing.
Besides polyether and polyester TPU products, the company’s Wanthane label includes aliphatic thermoplastic polyurethanes. These are used to make films for automotive exterior coatings.
The films increase the glossiness of automotive paints. Applying aliphatic thermoplastic polyurethanes can increase glossiness by around 30%. Thickness between 0.008 mm and 0.020 mm are used.
Additionally, the coatings can provide at least three years’ protection against discolouration and five years’ against ageing, said an article on Wanhua’s website.
Mobile phone screens could be another use for aliphatic thermoplastic polyurethane films, the article added.
