Nylon-6 is used in high performance applications due to its superior mechanical strength specially impact strength. In high speed machinery & also in many industrial applications metal parts are replaced by Nylon-6 due to light weight & thin/compact features. Nylon-6 is a tough resin and it is unique that its impact strength can go up multifold due to reinforcement say by glass fiber/special minerals & many other materials. Impact strength can also be enhanced of moulded parts by hot water annealing for 3-4 hrs to accelerate the process pf water absorption. Even at temperature conditions below 0 degree Celsius the notched & unnotched impact resistance of “CAPLON” Nylon-6 remains at high level.
For automotive components, the usage of Nylon-6 resin is widely used due to its excellent resistance to oil & Gasoline.
One major feature of Nylon-6 is very precise or sharp melting point. At temperature below melting point, material is solid & temperature above melting point, material becomes highly fluid in nature. The high melting point 220 degree Celsius makes Nylon-6 suitable for high temperature applications. For short exposure, it can work up to 140-160 degree Celsius range, however for long period exposure it can work safely up to 100 degree Celsius. Addition of various stabilizing agents & reinforcing material, Nylon-6 displays a higher heat distortion temperature and delivers a long service life.
Superior resistance to abrasion is must in material used in machine moving parts like bearings, gears, sliding parts & rods. Nylon-6 got excellent abrasion resistance & is widely used in moving machine parts.
Although Nylon-6 resin are used in exterior applications & have good weatherability however direct exposure of sunrays or ultraviolet rays affect mechanical properties like tensile strength & break strain. Thus incorporation of various additives & even carbon black pigment gives improvement in weather resistance of Nylon-6.
The special molecular chain that Nylon-6 is composed exhibits a good resistance to aliphatic & aromatic hydrocarbons, to Ketones, to Esters, to Alcohols & to organic acids with exception of formic acid. They have limited resistance to strong acids, phenols & metal chlorides. Chemical Resistance of a crystalline material is generally little higher than that which corresponds to the amorphous product.
The complicated injection moulded or extruded parts can be fused together or bonded together to make final assembled product by ultrasonic welding or vibration welding.
Due to superior physical, chemical & rheological properties, Nylon-6 is having excellent moulding & extrusion capabilities & covers a wide spectrum of complicated parts in various shapes.
“CAPLON” Nylon-6 products exhibits high level of electrical properties like CTR(Comparative tracking resistance), Dielectric strength & also surface/volume resistivity. The Electrical properties vary with temperature, humidity & also with specific grades. However it fulfills critical application requirements. Therefore Nylon-6 is widely used in all type of connectors, MCB housing & switches, bobbins & many other applications of Electrical/Electronic appliances & systems.
The flammability rating of “CAPLON” Nylon-6 is done as per UL94 classification & unmodified, unfilled grades are rated V-2 & reinforced grades are rated HB. There are unfilled & filled grades with halogenated & non halogenated flame retardant additives which are CUSTOM MADE as per requirement of customer to suit their specific requirement, and these grades are V-0 at 1.6 mm thickness.
