Automatic Low Temperature Flexibility Tester Waterproof Membrane -40℃ 304 Stainless

Product Features & Attributes
This automatic low temperature flexibility tester is used for low temperature flexibility testing of asphalt waterproofing membranes. It is essential equipment for waterproofing membrane manufacturers, quality inspection institutions and research universities.

Working Principle: After the specimen is cooled to the set temperature in the low temperature chamber, the mechanical lifting system drives the bending roller upward at a constant speed (360±40mm/min), bending the specimen 180° around the roller. The specimen surface is then inspected for cracks to evaluate the flexibility of the membrane at low temperatures.

Structural Features:

• All stainless steel construction: Main unit and inner chamber made of 304 stainless steel, corrosion-resistant and durable

• Double-movement parallel design: 8 parallel positions, testing five specimens on both front and reverse sides simultaneously for high efficiency

• Aviation plug connection: Controller connects to main unit via aviation plug for simple, safe connection and space saving

• Intelligent temperature control: Smart temperature controller with digital timer for precise control

Technical Features:

• Minimum temperature -40℃, cooling speed several times faster than ordinary freezers

• Temperature control accuracy ±1℃, resolution 0.1℃

• Test speed 360±40mm/min

• Time setting range 1 minute to 99 hours

• Equipped with Φ20mm, Φ30mm, Φ50mm double-movement bending rollers for 3, 4, 5mm thickness membranes

• Digital display of temperature and time

• Upper/lower stroke limit protection, trip protection for transmission faults

• Automatic temperature and time control with timer alarm

Applications:

• SBS modified asphalt waterproofing membrane low temperature flexibility testing

• Building waterproof coating low temperature flexibility testing

• Various asphalt waterproofing membrane low temperature performance testing

Available in different specifications: different bending roller sets (Φ20mm, Φ30mm, Φ50mm and custom), different temperature ranges (-20℃, -25℃, -40℃ and custom), and different power configurations (750W, 1000W) to suit various membrane types and testing standards.

Mainly used in waterproofing membrane manufacturers, quality inspection institutions, construction engineering quality inspection stations, research universities, waterproofing material R&D units, and more for low temperature flexibility testing of asphalt waterproofing membranes.
