Material information without obligation for Nylon 6.6

Physical and Mechanical Properties

Nylon absorbs a relatively high amount of water and, depending on the type of Nylon and its application it can be acclimatised in the factory to the ambient climate by conditioning (storing in warm water). Only then does normal Nylon demonstrates its good ductility, its excellent notch impact strength and its good resistance to stress cracks. These qualities normally have to be present in the Nylon when the parts are being assembled.

If parts made from Nylon have not been stored in the original packaging but at a dry and warm place, then they should be kept in warm water for 24-48 hours before assembly. Nylon parts shouldn't be assembled in frozen condition.

Nylon is characterised by very high service life and resistance to aging. Glass fibre reinforced Nylon displays a higher E-module and a higher toughness. The abrasion behaviour is good. If used with bearings, an additive of MoS2 or PTFE/Silicone gives excellent slip and minimal lubrication qualities.


Optical and Chemical Properties

Depending on the type of Nylon the basic tint is yellow-white, waterwhite or light-white. Nylon goes yellow with age and if it is exposed to UV-rays. Thus the colour is not consistent over a long period if used in parts in its natural colour. Given increased crystalline properties Nylon displays good resistance to aliphatic and aromatic hydrocarbons, oil, lubricants, grease, some types of alcohol, ester, ketones, ether, organic and inorganic bases up to a medium concentration, chlorated hydrocarbons such as carbon tetrachloride, freon, paints and varnishes. Chloroform and methyl chloride produce very strong swelling. Alcohols such as methanol and ethanol have a similar effect as water. Nylon is not resistant to solutions of oxidisation media, mineral acids and formic acid, strong lyes, phenols, cresols and glycols.

Resistance to Weather and Ageing

Nylon is adequately resistant to ageing and weather conditions. For external use the level of resistance can be increased by using a correct colouration , e.g. soot. In the case of glass fibre reinforcing Nylon the surface enlargement of parts produced by the glass fibre means that surface of parts is more stressed. The mechanical properties are not influenced to any great extent.

Special Uses - Product Ranges

Glass fibre and other fillers which increase strength, MoS2 and PTFE/Silicone designed to improve slide qualities, various stabilisers, materials with good conductivity or the improvement of the electrical conductivity. - Screws, nuts, shims, cogs, door and furniture fittings, slide bearings, bearing sleeves, fan wheels, pump casings, filter pads.

Thermic Properties

Glow properties and thermal forming consistency are good in the case of normal Nylon. In the case of glass fibre reinforced Nylon the wick effect of the glass fibre leads to a moderate flammability. The thermal forming consistenc is even better than with non-reinforced Nylon. Under increasing heat Nylon keeps it shape very well. In the case of glass fibre reinforced Nylon the heat expansion is still smaller. Depending on load and the design of the parts the range of temperatur for continuous use is between approx. -40° C and 80°-120° C. Nylon begins to disintegrate at temperatures above 300°C. It lits into flames upwards of about 450°-500° C. It burns with a low flame and a significant smell of burnt animal horn and then it begins to drip and crackle, forms strands, and in most cases the flames go out after a short time. For a short time Nylon 6 can also withstand temperatures of up to 200° C and Nylon 6.6 with 50 % glass fibre can withstand temperatures of up to 250° C.

Physiological Behaviour and Joint

It is not advisable to bring Nylon into contact with foodstuff which contain water if these are subject to heat for a longer period of time. Dry, non- reinforced injection-moulded parts made of Nylon can be welded via ultrasonic welding, friction- or vibration welding and hot element welding to give sound, tough joints. Dampness and glas fibre reduce the weldability. For purposes of adhesion, solvents and varnishes based on phenol or resorcin, concentrated formic acid, impact adhesives and cyanate glues are particularly suited for Nylon.
