Описание материалов:

HFDB-4202 NT is a long-life, water-tree-retardant, unfilled, crosslinkable, low density polyethylene insulation compound. The permanent tree-retardant additive provides improved performance in power cables in service involving exposure to moisture while retaining the excellent physical, electrical, and processing attributes of conventional, crosslinkable polyethylene.

HFDB-4202 NT Compound provides electric utilities with:

State-of-the-art "water" tree-retardant technology.

Proven in the field for over 25 years.

Excellent electrical performance.

Specifications
HFDB-4202 NT tree-retardant compound is designed for use in power distribution cables and especially in underground applications (with and without moisture barriers), providing for improved performance over XLPE cables. Cables insulated with HFDB-4202 NT, using sound commercial fabrication manufacturing practice, would be expected to meet the latest editions of the following specifications and regulations:

A review of detected contamination is incorporated into our quality program. Storage The environment or conditions of storage greatly influences the recommended storage time. Storage under extreme conditions may affect the quality, processing, or performance of the product. Storage should be in accordance with good manufacturing practices. The recommended storage conditions are dry conditions with temperatures between 50°F and 86°F (10°C and 30°C). When stored under these conditions, the product may be used by the customer for up to one year from the date of sale or two years from the date of manufacture, whichever comes first. It is recommended that the practice of using the product on a first-in / first-out basis be established.

Инструкции по экструзии
HFDB-4202 NT provides excellent surface finish and outstanding output rates over a broad range of conditions. For optimum results, melt extrusion temperatures in the range of 240 to 285°F (116-140°C) are recommended, although higher melt temperatures are possible on certain equipment with due care. Generally, a 60-40-20 screen pack is recommended. However, specific recommendations for processing conditions can be determined when the application and type of processing equipment are known.
