Spanish engineering for Japanese nylon

Last June, the Japanese group UBE, one of the world's largest nylon manufacturers, inaugurated the expansion project for its Castellón plant, thus increasing its production from 30,000 to 70,000 tonnes a year.

Following various expansions and technological innovations, this centre has become its largest in Europe and will cater for new markets such as the United States. 

The Japanese group came to the El Serrallo chemical complex in Castellón more than two decades ago, when it acquired the firm Proquimed. In 2013, UBE carried out an initial expansion, the project for which was also awarded to Ayesa, in "open book" mode.

As a result of the successful collaboration between the two companies, UBE once again trusted in Ayesa to carry out this large-scale expansion, awarding it the entire contract, in "open book" mode once again. This includes the reviewing of the basic engineering carried out by UBE, the detailed engineering, purchases management and the construction of the new manufacturing line.

It's the largest industrial project carried out by Ayesa to date, especially in the field of chemicals. And not just due to the size of the contract, but also due to the technical complexity, cost and demanding execution deadlines.



Polyamide or nylon is a growing market as the most technologically advanced firms are increasing their demand to replace the use of polyvinylidene chloride film (PVDC), used for food and hygiene product packaging and detergents.

The new plant can produce various types of medium and high viscosity nylon and copolymers, with technical applications in the automobile and food protection industries and the industrial manufacturing of monofilaments, fishing nets and other engineering components.

UBE produces nylon resin in three plants spread throughout the world, with a combined annual capacity of 198,000 tonnes of product, of which 70,000 correspond to Spain

Its product is particularly recognised for its quality and great processing capacity in extrusion applications, such as film for the packaging of food products.
