Technical Features:

ZEC's GT Textile Protection Sheaths are especially suitable for hydraulics and pneumatics for the containment of single and multiple hoses. These sheaths have excellent resistance to mechanical stress, are compatible with many oils and organic products and their working temperature ranges from -40° to +100°C.

ZEC's GT Textile Protection Sheaths are made of high toughness textile fiber and provide excellent resistance to abrasion. Ad shown by lab tests (see Fig. 1), the sheath exceeds 5000 test cycles in line with UNI ISO 6945 Standard.

As concerns oil containment in the case of accidental hose burst, ZEC's GT Textile Protection Sheaths provide excellent shielding to oil squirts and this is confirmed by lab tests (Pin Hole Test) performed by bursting the hoses in accordance with SAE100 J343 Standard and comparing the state of the sheath before and after the burst (Fig. 2).

ZEC's GT Textile Protection Sheath works as a barrier for the surrounding environment, without showing any structural failure. Therefore this sheath ensures a good degree of protection in the event of hose accidental breakage, in line with ISO 3457 standard.

A further verification of the resistance degree of ZEC's GT Textile Protection Sheath is the tensile stress at break test performed on the sheath in accordance with ASTM D885 Standard, comparing the result with traditional sheaths found on the market. ZEC's GT Textile Protection Sheaths feature a tensile stress value at break that is about 2 times that of conventional sheaths on the market today (see Fig. 3).

ZEC's GT Textile Protection Sheath is UV-stabilized and has an excellent resistance to UVA aging. This sheath is therefore suitable for outdoor applications in the presence of sunlight and climatic agents. This characteristic has been tested in a climatic chamber (Weiss WK-270/70/15, Fig. 4) by subjecting the sheath to UVA radiation for 720 hours at 50°C.
After this conditioning the sheath did not show any signs of deterioration or aging.

ZEC's GT Textile Protection Sheaths also have an excellent resistance to heat, proven by the Softening Point (150°C) and low thermal conductivity. The raw material used in the production of EC's GT Textile Protection Sheaths complies with RoHS 2 (2011/65/EU) European Directives.
