BASF adds Ultramid C37LC

In film applications, Ultramid C37LC allows manufacturers of shrink film for food packaging to achieve higher hot water and hot air shrinking, meaning they can forgo the usual admixture of amorphous polyamides. This makes the production process for films leaner and more efficient, BASF stated.

The improved properties of Ultramid C37LC avoid undesired curling of asymmetrical multi-layer films with polyethylene or polypropylene, which are used for stand-up pouches, lid films and deep drawing applications. By reducing the melting point of Ultramid C37LC to 182 degrees C, the usual effort for post-treatment in form of a water bath or the admixture of amorphous polyamides can be omitted.

Films produced with Ultramid C37LC also have a low crystallinity, and are therefore significantly softer and more transparent than films made with conventional copolyamide.

Further, the properties of Ultramid C37LC allow manufacturers of fishing nets and fishing lines, monofilaments, to improve the tear resistance or knot strength of their product. Its use in the production process for monofilaments, sees the need for the admixture of amorphous polyamides or caprolactam removed.

‘Ultramid C37LC is a huge step forward,’ emphasized Frank Reil, head of marketing and new business development for polyamides at BASF. ‘It will redefine the standard for shrink films and monofilaments. This is our way of fulfilling the industry's request for higher product quality and efficiency in the manufacturing process.’

BASF is the leading supplier of high quality polyamides and polyamide intermediates for the engineering plastics, film, fiber and monofilament industry. The product portfolio includes Ultramid B (polyamide 6), Ultramid C (polyamide 6/6.6 copolymer) and Ultramid A (polyamide 6.6). The product offerings are supplemented by technical services for customers. BASF operates Ultramid polymerization plants in Ludwigshafen, Germany, Antwerp, Belgium, Freeport and Texas, USA and Shanghai, China.
