Properties and Materials

While the descriptions and information contained below are presented in good faith and believed to be accurate it is provided for guidance
only. Because many factors affect application and use we recommend that you make tests to determine the suitability of a product
for your particular purpose prior to use.

Nylon 6/6 Polyamide
General purpose nylon 6/6 has good toughness, tensile strength and resistance to creep, particularly in the high temperature range.
Nylon has excellent wear properties, low coefficient of friction and exceptional chemical resistance particularly to aromatic hydrocarbons,
greases and oils. Nylon is a hygroscopic material. Moisture acts as a plasticizer reducing the tensile strength/ stiffness and increasing
elongation/ impact strength/ energy absorbing characteristics. Outdoor weathering can be improved by the addition of carbon black.
Nylon will perform well in long range service in most applications at temperatures as high as 85° C. The natural colour is translucent off

Nylon 6/6 Heat Stabilized
Nylon heat stabilized has the same mechanical properties as general purpose nylon 6/6 with the additional advantage of heat stabilization.
This material will withstand 121°C in long range service in most applications. Most stock items are black.

Nylon 6/6 Flame Retardant
Flame retardant nylon 6/6 has similar properties to general purpose nylon 6/6 with flame retardant additives for UL94V0 rating.

Nylon 6/6 30% Glass Reinforced
Nylon 6/6 33% glass reinforced has outstanding property improvements over un-reinforced compositions. Improvements include greater
tensile strength, deflection temperature, shear strength, improved creep resistance, better dimensional stability, lower moisture absorption
and thermal expansion. The good wear resistance, electrical properties and low coefficient of friction of un-reinforced nylon 6/6 are
retained. Nylon 33% glass reinforced is opaque tan in colour.

Nylon 46 Polyamide
Nylon 46 is a high temperature nylon which bridges the price performance cap between traditional nylons and high performance materials.
It has excellent short and long term heat resistance, high stiffness at elevated temperatures, high creep resistance, outstanding
toughness, excellent fatigue behaviour, good chemical resistance and higher continuous use temperature. Nylon 46 is translucent off
white in colour.

Acetal Copolymer (POM)
Acetal resins have strength, stiffness and hardness over a wide range of temperatures, humidity environments and stress. Acetal absorbs
little water minimising the effect of moisture on its physical properties. Acetal resists neutral oils, grease, petroleum based fuels, many
organic solvents and alkalis. Oxidizing agents and acids, organic and inorganic, with a PH less than 4 will attack acetals. Acetal is widely
used in plumbing and irrigation because it resists scale build-up and has excellent thread strength.

High Density Polyethylene (HDPE)
Polyethylene is among the lowest density plastics and therefore is one of the lowest cost per volume. High density polyethylene has
good toughness, excellent electrical properties and chemical resistance, good low temperature brittleness and very low water absorption.
Polyethylene is essentially inert, unaffected by strong and weak acids, alkalis, detergents, alcohols and ketones. Polyethylene has
low tensile strength and is subject to considerable creep and stress relaxation under load. Polyethylene will swell with chlorinated and
aromatic hydrocarbons including gasoline and oils.

Polycarbonate (PC)
Polycarbonate is one of the toughest, most dimensionally stable thermoplastics over a wide temperature range. Polycarbonate has exceptionally
high impact strength. It is unaffected by water below 60° C and can be used in boiling water on a limited basis. It is unaffected
by greases, oils, detergents, aliphatic hydrocarbons, most mineral acids and the higher alcohols. It is attacked by chlorinated hydrocarbons
and most aromatic solvents, esters and ketones. Polycarbonate has white water transparency with a 90% light transmission.

Polypropylene (PP)
Polypropylene has a good combination of rigidity and toughness at elevated temperatures, can be steam
sterilized, good abrasion resistance and low coefficient of friction, non-hygroscopic, excellent electrical properties,
unique flex properties, good chemical resistance without stress cracking, PP has one of the lowest densities and a high surface gloss. It
has excellent chemical resistance to dilute acids, concentrated acids (except oxidising acids)
alkalis, alcohols and detergents. PP resists aromatic hydrocarbons, chlorinated hydrocarbons, greases and oils
at room temperature but it is attacked at about 60° C.
