Capa™ significantly enhances biodegradability & bioplastic performance

Perstorp to launch perfect polyester for bioplastics blends at K Fair 2013

Perstorp, world leader in specialty chemicals, will be launching its proven technology Capa™ Thermoplastic products for bioplastics at K Fair, 2013. Considerable investments have been made in caprolactones to ensure we deliver new Capa™ products that address key issues related to plastic materials, such as sustainability, biodegradability and product safety.

Bioplastics are receiving enthusiastic attention today because they save on resources and offer the unique potential of carbon neutrality. With a projected growth in bioplastics of 500% between 2011-2016* this is a very exciting growth area. Perstorp, the world leader in caprolactones, a biodegradable polyester, has made substantial investments in the development of Capa™ for bioplastics.

Bioplastics that are biodegradable, such as PLA (PolyLactic Acid) and TPS (ThermoPlastic Starch), are becoming increasingly attractive to both consumers and producers, as they offer new ways of recovery and recycling. Perstorp’s caprolactones enhance the properties of bioplastics allowing them to be used for new market opportunities and applications. Capa™ provides superior biodegradation, easier processing and compatibility.

Capa™ – the perfect polyester for bioplastic blends
Capa™ is the perfect polyester for bioplastics blends, improving several mechanical properties as well as accelerating biodegradation of the biopolymers. Bioplastics with Capa™ biodegrade quickly in the right conditions – you can use domestic composting, rather than industrial requiring a higher temperature. Capa™ also offers excellent tear properties by adding mechanical strength, and making the bioplastic more flexible, so that it elongates and stretches rather than tears. The excellent low temperature performance allows bioplastic products to be used in cold environments.

With Capa™ you achieve a more durable product for a longer life with better compostability at end of life. The low melting point reduces energy consumption when processing to a minimum. This all adds up to a very sustainable and practical solution for bioplastic producers.

Capa™ facilitates new opportunities for other bioplastics
The synergy effects of adding Capa™ to biopolymers mean greatly increased opportunities. For example, by adding Capa™, PLA can be used in film applications. Capa™ can be easily blended with PLA and starch based polymers to attain customized and desirable properties that really broaden their appeal.

Wherever you can use biopolymers you can use Capa™ that is ideal for both renewable and disposable polyesters. In disposables – for plastic bags, compost bags, coated paper and one-time plastic cutlery, and in renewables – for cutlery, trays and items that need to last a year or two. Bioplastics are now broadening out into electronic equipment, such as mobile handsets and casings, and making inroads into automotive parts too. Capa™ is an essential part of this journey into these new market segments.
