Rubber and Waterproofing Material Testing Equipment
Our company has newly developed a key piece of equipment for dispersing polymer‑cement waterproof coatings in laboratory settings, capable of fully programmable, multi‑stage control with adjustable speeds. Its design is sleek, compact, and refined, featuring a user‑friendly interface that meets the operational needs of laboratory personnel.
LBTZ-26 Fully Automatic Low-Temperature Flexibility Tester for Polymer Cement Waterproof Coatings
The fully automatic low-temperature flexibility tester is an upgraded, redesigned version of the electric digital-display low-temperature flexibility tester. Its refrigeration chamber is constructed from stainless steel, with a minimum temperature reaching −45°C.
Designed and manufactured in accordance with GB/T 23445-2025. Used to determine the lowest temperature at which an asphalt waterproofing membrane, under specified conditions, can be bent around a prescribed bending rod without cracking.
LBTZ-28 Single-Sided Testing Apparatus for Vulcanized or Thermoplastic Rubber
The single-sided alkali resistance test apparatus for rubber evaluates the effects of a liquid on rubber by measuring changes in its properties before and after immersion in the test liquid; it is intended for tests in which only one surface of the specimen is in contact with the liquid.
LBTZ-1 Electric Color-Screen Low-Temperature Softness Tester (New Standard)
Low-Temperature Flexibility Tester: This instrument is specifically designed for assessing the low-temperature flexibility of waterproofing membranes, in compliance with national standards GB/T 328.14‑2007 and GB/T 23445‑2025. These standards explicitly stipulate that low-temperature flexibility testing must be conducted using automated mechanical methods to eliminate human‑induced variability. The Low-Temperature Flexibility Tester is an essential piece of equipment for testing laboratories, manufacturers of waterproofing membranes, and quality‑control departments.
LBTZ-6A Rubber Shredding Machine (for plastics, leather, wires, and cables)
To meet the new requirements put forth by testing institutions at all levels for the mechanical and physical property testing of polymer insulation and sheathing materials, a waterstop punch‑and‑shaving machine (also known as a slicing machine) has been developed under the guidance of relevant experts at the Suzhou Institute of Waterproofing Materials.
LBTZ-51 Waterproof Membrane Lap Joint Impermeability Tester
The waterproof membrane lap‑joint impermeability tester complies with the national standards GB 55030‑2022 and GB 45320‑2025, which set mandatory requirements for waterproofing in building and municipal engineering. Additionally, the national standard “Safety and General Technical Specifications for Building Waterproof Membranes” has introduced a new requirement for the “impermeability of lap joints” of waterproof membranes. This requirement applies to all lap‑joining methods, including heat‑fusion, welding, self‑adhesive, adhesive‑bonded, and tape‑sealing processes. Upon formal implementation of these standards, “lap‑joint impermeability” will become a mandatory criterion in the quality acceptance of waterproof membranes.
The constant‑temperature and constant‑humidity chamber for evaluating the water vapor transmission properties of rigid cellular plastic building materials, equipped with various permeation cups, enables conditioning and testing under controlled environmental conditions for hygroscopic and non‑hygroscopic building materials, as well as rigid cellular plastics and their products—including those with natural skins or surface finishes.
ZSY-1 Electric Digital Display Low-Temperature Flexibility Tester

ZSY-2 Waterproof Membrane Impermeability Tester (Low Pressure)
It is suitable for measuring low-pressure conditions in asphalt and polymer sheet materials, such as roofing, substrates, and vapor barriers, and offers advantages including simple operation and stable performance.
ZSY-3 Waterproof Membrane Impermeability Tester (Method B)
This instrument employs an electric pump for pressurization, with electrical automatic control of gas injection and pressure application, as well as automatic pressure maintenance and digital display timing. When the test pressure does not exceed 0.6 MPa, this device can also be used to determine the air permeability or water permeability of other relevant materials.
Rubber test specimens are ground to a specified thickness for use in other testing equipment. It is one of the devices employed in rubber quality inspection.
Suitable for blanking and stretching test specimens, as well as test pieces of various shapes, it is widely used in construction laboratories, research institutions, and for sampling rubber materials.
It can cut test specimens with a Shore hardness greater than 40 and a thickness of 1–16 mm. The cut surfaces are smooth and flat.
ZSY-7 Type Heat-Resistant Suspension Device
It is used to determine the flow resistance of waterproof membranes and coatings at elevated temperatures, assessing the heat‑resistance limits of the membrane’s top and bottom surfaces under specified temperature conditions or under continuous exposure to varying humidity levels. It serves to verify product heat‑resistance requirements, to establish the heat‑resistance limit of a given product, and to evaluate changes in performance after aging. The apparatus consists of clamps, a marking device, pins, and other components.
This flexometer is designed and manufactured in accordance with the GB/T 328 standard. It is used for low-temperature bending tests of waterproofing membranes and waterproof coatings.
ZSY-9 Electric Hydraulic Sampler
Design Patent: ZL 2024 3 0768956.0 For sampling various waterproof material specimens, with simple and convenient operation.
This instrument is suitable for measuring the thickness of waterproof materials and sheet products.
ZSY-11 Digital Thickness Gauge
This instrument is suitable for measuring the thickness of waterproof materials and sheet‑type products. It is designed and manufactured in accordance with the GB/T 328 series and complies with the relevant standards specified in GB 18173, GB 18242, and GB 18243.
