GW series
The GW series are flame-retardant PVC compounds that meet flame requirements up to UL 1666 riser.
The flame-retardant PVC compounds in the GW series are formulated to pass strict fire testing requirements dictated by the NEC NFPA 70 up to the UL 1666 riser standard.
GW series: where fire safety meets performance.
With flame-retardant properties, GW series compounds promote safety in wire and cable applications. They meet flame test requirements up to UL 1666 riser, ensuring that they can withstand and limit the spread of fire in riser-rated cable installations. This feature is key in reducing the risk of fire propagation in buildings and other structures, protecting lives and property in residential, commercial and industrial settings.
The GW series is suitable for a variety of cable types, including copper and fiber optic cables. The range of materials features both semi-rigid and flexible options and is adaptable to various installation requirements.
The versatility of the GW series of PVC compounds allows it to be used in various applications, from communication cables to control and signal cables, offering a high-quality solution for manufacturers and installers who need a single compound that can meet diverse needs.
The GW series is formulated to meet strict NEC fire test standards.
Further optimizing safety across residential and commercial applications, grades in the GW series are formulated to meet the strict fire testing requirements dictated by the National Electrical Code (NEC) NFPA 70, including:
-
UL 1581 for wire and cable construction and performance standards.
-
UL 1685 / FT4 for vertical-tray fire-propagation and smoke-release testing.
-
UL 1666 riser standards for flame propagation resistance in vertical installations, minimizing fire spread risk in buildings.
Additionally, various GW compounds are recognized by Underwriters Laboratories (UL) under category QMTT2, recognizing specific safety and performance criteria is met.
Certain grades have undergone rigorous testing to assess their suitability for electrical applications, resistance to sunlight and long-term insulation resistance in water, oil and gasoline in order to obtain QMTT2 recognition.
The GW series balances performance with safety requirements - ideal for versatility in wire and cable designs.
The GW series includes flame-retardant PVC compounds designed to balance thermal performance, flame resistance, electrical properties, and application versatility for wire and cable designs.
