Material Specifications:
Nelco Products offers a wide variety of cable ties designed for use within specific environments. Listed below are several environmentally limiting factors to the durability of some cable tie materials such as UV light and chemical corrosion. Please read carefully to determine, which material is best suited for your specific application or consult the material specification chart at the bottom of the page. To request a quote on a specific type of cable tie return to the main list of cable ties and choose the cable tie best suited to your intended application.
General Purpose Applications
Nylon 6/6 – General Purpose
General purpose nylon 6/6 is suitable for use in most practical applications at a continuous temperature up to 150°F. Nylon 6/6, the grade most often used for cable tie production, meets UL 94V-2 flammability ratings. Its working temperature range is from -40°F to 185°F.
Outdoor Applications
Nylon 6/6 – UV Stabilized
UV Stabilized Nylon 6/6 is used in continuous or extended exposure to outdoor sunlight. The nylon cable tie is a weather resistant grade, enduring additional ultraviolet (UV) light. This grade is produced by incorporating stabilizers in the nylon resin. UV Stabilized Nylon cable ties are available only in black.
Nylon 6/6 – Heat Stabilized
Heat Stabilized Nylon 6/6 is used in continuous or extended exposure to high temperatures (up to 250°F). A general-purpose nylon will have a reduction in physical properties and fatigue as a result of high temperatures. Nylon cable ties containing specially formulated heat stabilizers provide additional thermal endurance. Heat stabilized nylons are engineered for continuous exposure to temperatures above 185°F, which meet UL standards for electrical applications.
Nylon 12 – Weather Resistant
Weather Resistant Nylon 12 has a UL relative thermal index rating of 194°F (90°C).
Nylon 12 Material is resistant to most salts & chemicals and is rated for outdoor use for 12-15 years. An ideal solution for solar applications. Nylon 12 Material has low temperature toughness down to -40°F (-40°C) with a notched izod rating of 1.3ft lbs/inch at room temperature.
Chemical Resistant Applications
Polypropylene – General Purpose
Polypropylene is used in environments where chemical effects on nylon are a concern, because it is not affected by inorganic acids (hydrochloric), polyhydric alcohols (ethyleneglycol), neutral salts (sodium chloride), and basic salts (sodium bicarbonate). Polypropylene also resists a number of other chemicals with good results although it has a lower tensile strength than nylon 6/6. In addition, this material has the ability to withstand ultraviolet light exposure.
Tefzel*
Although weaker than general purpose nylon 6/6 (about 37%), Tefzel is resistant to a wide range of chemicals such as concentrated hydrofluoric and sulfuric acids. It is also a low water absorbing material, therefore, moisture has a minimal effect on it. Tefzel is radiation resistant up to 100 megarads and meets IEEE requirement 333. Tefzel also withstands high temperatures, ultraviolet light exposure, and meets UL flammability requirement 94V-0.
PEEK
Designed for harsh environments where a cable tie material is required to hold up to chemical, high radiation, and/or high operating temperature environment. They are made of a non-conductive material that is excellent for high temperature applications up to 500°F (260°C). They have a flammability rating of V-0 with low smoke and toxicity. PEEK material meets MIL specification MIL-P-46183, and is approved for use by The Department of Defense.
Flame Retardant Applications
Halar**
Halar is similar to Tefzel in performance. Its outstanding characteristic is a lower smoke density when burned. This makes Halar more desirable for use in areas where smoke generation is a concern, as when bundling wire in plenum spaces.
FLEXties (Hook & Loop Cable Ties)
HTH (888)
A unique back-to-back fastening system featuring a polyethylene hook laminated to a nylon loop without the use of an adhesive.
HTH (889)
A flame retardant version. This product meets UL requirements for a rating of 94V-2 and also meets requirements for FAR 25.853 A/B. Specified configurations of black HTH (889) meet the requirements for use in air handling applications in accordance with NEC’s section 300-22 (C) & (D).
Stainless Steel Specifications
Type 304 Stainless Steel
Type 304 is an all-purpose austenitic, low carbon 18-8 chromium-nickel stainless steel. It has good corrosion resistance and weldability. Type 304 is the most widely used stainless steel. It is found in chemical and food processing equipment, hospital and paper mill equipment, heat exchangers, etc.
Type 316 Stainless Steel
Type 316 is an austenitic chromium-nickel stainless and heat resisting steel with superior corrosion resistance. It is extensively used in marine atmospheres and environments where it is subjected to various chemicals, salts, acids, and high temperatures. Type 316 has superior creep strengths at elevated temperatures.
