WEB EXCLUSIVE: A new series of reinforced nylon 612 compounds from Teknor Apex Co., Pawtucket, R.I., are offered as alternatives to nylon 12 for injection molded automotive fuel-line components. They are said to provide the required chemical resistance plus shorter molding times than nylon 12.
Chemlon 813 CI and 830 GHI compounds have been shown to gain only slightly more moisture (<0.2%) than nylon 12. Existing tooling for nylon 12 can be used with little or no modification, according to Teknor. With 13% carbon fiber loading, Chemlon 813 CI provides the antistatic conductivity often called for in fuel-line components; while Chemlon 830 GHI with 30% glass fiber offers enhanced strength and rigidity for applications such as connectors.
