Perstorp continues to grow

Speciality chemicals company Perstorp is, by its own measure, the world’s largest supplier of caprolactones and its derivatives. The company’s current investment to double the production capacity of its Warrington, UK, site is on track to reach mechanical completion by the end of the year and begin commissioning in early 2011. The full capacity expansion is expected to be on stream in the summer of 2011.

Perstorp says its investment is a direct response to the growing market demand for caprolactone-based technology, which is increasing by >5 % per year. This investment is key to securing the future of the caprolactones industry and ensuring reliable supply for formulators who are already using or interested in exploring caprolactone-based technology in their applications, says the company.

"Our investment in a doubled capacity for caprolactones has continued throughout the global economic recession," Vice President of Caprolactones Mårten Olausson comments. "We have a strong belief in the future of the Capa product range and are committed to supporting and developing the caprolactone market."

According to Perstorp, in polyurethane applications where performance is the key differentiating factor, the company's Capa caprolactones present an attractive alternative for improving properties and end-product quality in many coatings, adhesives, sealants, and elastomers applications. Capa polycaprolactones allow formulators to tailor even more precise properties in their end products, says Perstorp. They also possess low viscosity, resulting in improved processability and lower VOC levels. They are especially used in applications such as injection grade TPUs, PUD synthesis, cast elastomers, reactive hot-melt adhesives and light stable flexible coatings for leather and many other substrates.

"We are investing heavily in our Capa caprolactones and predict a bright future for these products that complement our portfolio of special polyols perfectly and give our customers an edge in spearheading the development of new products and applications," Olausson adds.
