Technical Data

 

产品说明

 

RN66N50HL is a nylon 6.6 formulation, nucleated to accelerate crystallization and enable very fast cycle times to be realized, especially in multi-cavity tooling; a special lubricant system is also incorporated for ease of mold release. Compared with a general-purpose product such as RN6650L, this nucleated grade exhibits higher strength and rigidity, but lower practical toughness. Mold shrinkage is also lower, and more isotropic, often resulting in reduced tendency for warpage.

 

RN66N50HL is Recognized by Underwriters' Laboratories under File No. E 148796; details of Relative Thermal Indices, and electrical PLC values, are available from Michael Day Enterprises, or on line at www.ul.com/plastics.

 

RN66N50HL has also been evaluated according to the requirements of U.L. 1446 and IEC Standard 61857 and is Recognized under U.L. File No. E164279 for use as the Ground Insulation in both Class 130 and Class 155 Electrical Insulation Systems. Full details are available from Michael Day Enterprises, or from UL at data.ul.com/systems.

 

RN66N50HL has a non-tinting heat stabilizer incorporated into the formulation enabling it to be used for applications where preservation of natural color is critical.

 

Nylon 6.6 offers a unique combination of strength and toughness, excellent static and dynamic fatigue resistance, natural lubricity and resistance to the effects of a broad range of chemicals, oils and solvents, and is therefore used in such markets as electrical, electronics, communications or appliances where this performance combined with Underwriters' Laboratories Recognition is required.
