POLYPROPYLENE COMPOUND FOR SOLID INSULATION OF COMPUTER, INSTRUMENT AND TELEPHONE WIRE

Maxxam S551 is a fully stabilised solid PP copolymer block for applications requiring superior mechanical properties at elevated temperatures. Maxxam S551 is suitable both as primary insulation and as the skin layer in foam-skin constructions.

Maxxam S551 is fully stabilised for thermal ageing and copper contact.
Maxxam S551 exhibits outstanding heat resistance and long-term stability.

On the finished cable, Maxxam S551 provides a smooth surface, excellent electrical and dimensional stability, and outstanding mechanical properties.

SAFETY

Maxxam S551 is not classified as a dangerous preparation.

The product is supplied in form of free-flowing granules of about 3 - 4 mm size and can be readily handled with commercially available equipment. All handling and transport of the product may generate some dust and fines that constitute a potential risk for dust explosion. All metal parts in the system should therefore be properly grounded. Properly designed equipment and good housekeeping will reduce the risk. Check and follow local codes and
regulations!

Inhalation of any type of dust may irritate the air passages and should be avoided.

The product is intended for industrial use only. A Materials Safety Data sheet is available on request. Please contact your PolyOne representative for more details on various aspects of safety, recovery and disposal of the product.
