PP COMPOUND FOR CELLULAR INSULATION OF COMPUTER
AND INSTRUMENT CABLES

DESCRIPTION
F 552 is a cellular polypropylene copolymer for high performance applications. It is designed for computer and instrument cable insulation.

F 552 has a high vicat softening temperature and, as such, is more resistant to elevated temperature deformation than are cellular polyethylene resins. During extrusion, F552 provides an excellent surface finish and a uniform cell structure, with corresponding electrical and mechanical properties.

F 552 is fully stabilised for thermal ageing and copper contact.

SAFETY
F 552 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 Datasheet is available on request. Please contact your PolyOne representative for more details on various aspects of safety, recovery and disposal of the product.
