Features
- Very good resistance to corrosive chemicals, gases such as hydrogen sulphide, acids, alkalis, and highly offensive salts.
- Permanent bonding to concrete substrates prevents de-lamination due to high groundwater backpressure.
- Unaffected by constant exposure to high humidity and water.
- Strong sanitary bacteria and ever-growing fungus do not affect the T-Lining.
- Highly effective resistance to gas penetration.
- Joints are heat welded to form a continuous lining over the entire structure.
- If damaged, it can be repaired quickly and easily by removing the damaged area and welding another piece in its place.
- Flexible liner is able to bridge cracks in the structure without peeling of the T-Lining material.
- SanGrip T-RIB remains flexible within a wide temperature and between 75 degree C and 40 degree C.
- Can be welded at any time over its lifespan using a variety of Welding methods: Hot air Fusion – Speed weld/ Hot wedge type/ Extrusion type.
- Can be used as As a Tank Lining : ideal for a wide range of chemicals and can withstand continuous immersion up to 71 degrees C, but upper temperature limits depending on type and concentraton of materials.
- Dielectric Strength: SanGrip T-RIB is a non-conductor of electricity and resists electrolysis. The dielectric strength of the basic resins [using ASTM D149 test method, short time test] is 400-850 volts per Mil (25 Microns) of thickness.
- Water Absorption Rate : (% change maximum in original weight) to ASTM D 570. Results are 0.1% over first 24 hours then the rate drops rapidly. Total absorbed amount is not increased over prolonged period.
- Water Vapour Transmission Rate : Using ASTM E96 test method, [38 degrees C and 100% relative humidity] the transmission rate is about 0.020 (per 100 square inches per day) for 1.5mm thickness sheet.
- Co-efficient of Linear/Thermal expansion : ASTM D696 Test method gives a rate of 1.2 x 10-4 per degree C rise in temperature. SanGrip T Rib Liner Sheets do not exhibit significant contraction / expansion differentials to concrete.
- Hardness – Shore Durometer 'D' is 55 at 25 degrees C. (ASTM D 2240 test method).
- Tensile test of T-RIB lining/Weld Strength (ASTM D638 Test Method):
- Mainline Sheet : Average around 3600 psi (25 N/MM2) Field Weld All type
- Shear Test: Parent material fails before weld.
- Elongation of T-RIB Sheet : From 600% for HDPE to 900% for LLDPE and special resin HDPEs.
- Abrasion Resistance : ASTM D1044 test method. Wheel CS17 with loading of 1 kilogram. Weight loss is around 18mg per 1000 cycles.
- Coefficient of Friction: To ASTM test method D1894; static value 0.74Kinetic Value : 0.55
- Specific Gravity (ASTM D792) : Specific Gravity for LLDPE is 0.92. Specific Gravity for HDPE is 0.93 .
- Tear Resistance (ASTM D1004 Die C) : Test Method - Thickness 1.82 mm /Average 300N.
- Low Temperature Brittleness (ASTM D746 ) : Test Method : -94 degrees F.
- Modulus of Elasticity (Secant Modulus) : Expressed in Pounds per square inch.: 15,000 psi for LDPE and 25,000 psi for HDPE
- Chemical Resistance : After conditioning to constant weight at 43 degree C (110 degree F) tensile specimens and weight change specimens shall be exposed to the following solutions for a period of 112 days at 25 degree ±3 degree C(77 degree ± 5 degree F).
- At 28-day intervals, tensile specimens and weight change specimens shall be removed from each of the chemical solutions and tested. If any specimen fails to meet the 112-day exposure, the material will be subject to rejection.
