Niax™ L-5690 Silicone Copolymer

More About Niax™ L-5690 Silicone Copolymer

Niax L-5690 copolymer offers significant improvement in the production of low-density foams that are applied to a textile substrate and thermally cured. It can also help to reduce bubble coalescence in oven-cure conditions. 

Niax L-5690 copolymer is compatible with a number of standard surfactants in high-shear mechanical mixers that incorporate dispersed air into a urethane system before being applied to a substrate. It is effectively used for the creation of lightweight, supple foams with a fine microporous cell structure, such as those extensively used to manufacture carpet backing, head and door liners in cars, gaskets, leather substitutes and two-faced tapes. 

Niax L-5690 copolymer is also used to help regulate cell size, and is able to aid in stabilization of mechanically-frothed formulations. Selected for the development of foams used in a range of medical devices, Niax L-5690 copolymer can reduce instances of shear-induced cell collapse when, for example, it is subjected to a scalpel blade. For industries where VOC emissions are being more strictly scrutinized, including the medical and automotive industries, Niax L-5690 copolymer can enable medical foams and vehicle seating systems to be manufactured with reduced VOCs . 

Potential applications for Niax L-5690 copolymer include:

• Carpet backing
• Leather alternatives and specialized fabrics for upholstery
• Automotive seating systems
• Automotive head and door liners
• Tapes
• Gaskets and seals
