Perstorp launches Capa™ Lactide 8000 Series polyols for high-performance sustainable polyurethanes at UTECH Europe 2015

14 April 2015

A new range of Capa™ Lactide copolyols from Perstorp provides polyurethane formulators with increased opportunities to create high performance products with reduced carbon footprints. Perstorp is unveiling three diols and one triol at UTECH Europe 2015 (on stand 2100), the international polyurethanes exhibition and conference being held in Maastricht, the Netherlands, on April 14-16.

Capa Lactides at UTECH Europe 2015Capa™ Lactides in the new 8000 Series are liquid polyols produced by copolymerizing Perstorp’s well-known Capa™ caprolactone with renewable lactide monomers. Depending on grade, they have up to 50% renewable content. They have the same high level of quality and consistency that users of our Capa™ caprolactone polyols are already familiar with. “They are made using a new polymer chemistry unique to Perstorp, and they have been specifically developed to enable formulators to fine-tune performance properties,” says Joel Neale, Project Manager Innovation.

All four new high performance polyols are liquids at room temperature with improved solubility, enabling formulators to reduce or even eliminate the use of solvents. They are suitable for a wide range of polyurethane elastomers, adhesives and coatings.

Capa™ Lactides provide enhanced performance in adhesives of various types. They increase adhesion to demanding substrates, they increase hardness without increasing isocyanate content of the final formulation, and they can also provide extra open-time. Formulators will also appreciate the increased level of sustainability the polyols provide via their renewable content.

The new copolyols are also likely to find applications in thermoplastic polyurethane (TPU) adhesives. They provide high resistance to wear and abrasion, as well as to oils and chemicals. Their optical clarity and minimal haze ensure the appearance of adhesive joints and cast elastomers remains consistent throughout a product’s useful life.

With their medium molecular weight, low viscosity and low crystallinity, Capa™ Lactides provide polyols with properties that make them particularly suitable for soft-feel coatings. These coatings are characterized by high resistance to UV radiation, a property critical for consumer electronics and applications such as automotive interiors.

Capa™ Lactides are transparent, contributing to the optical qualities of coatings. Their low viscosity facilitates processing, while their high quality and consistency is hard to match by other renewable alternatives.

Perstorp developed the Capa™ Lactides on its new pilot plant in Warrington, UK. The pilot plant is close to the company’s main production facility for Capa™, ensuring fast transfer from pilot to commercial scale. The four Capa™ Lactides in the 8000 series are now commercially available and Perstorp will continue to work with customers to perfect the offering.

A technology expert will be on the Perstorp stand at UTECH Europe 2015 to discuss the new products.
