Material & Production Process
PVC waterstop is manufactured using polyvinyl chloride resin as the main raw material, combined with plasticizers, stabilizers, lubricants, and other additives. The combination of additives determines the product's flexibility, weather resistance, and durability. Our formulation is optimized in the following aspects:
Plasticizers – Control hardness, ensuring no brittle fracture at low temperatures and no excessive softening at high temperatures
Stabilizers – Improve thermal stability, reducing the risk of decomposition during processing and service
Lubricants – Enhance extrusion performance, resulting in a smooth surface and uniform dimensions
The production of PVC waterstop involves the following main steps, each with in-process quality control:
Mixing：PVC resin and various additives are fed into a high-speed mixeraccording to the formula and blended until uniformly dispersed
Pelletizing：The mixed material is processed into uniform pellets by an extruder-pelletizer, ready for the next stage
Extrusion：The pellets are melted and homogenized in a single-screw or twin-screw extruder, then continuously extruded through a die of therequired cross-section
Cooling & Setting：The extruded strip passes through a water tank or cooling rollers torapidly set and maintain dimensional accuracy
Cutting & Packing：Cut to customer-required lengths, inspected, then coiled or stacked forpackaging and warehousing
FAQ
How to store PVC waterstop?
Store PVC waterstop indoors in a cool, dry, and ventilated place away from direct sunlight and heat sources. Do not stack heavy items on top. Avoid contact with solvents, oils, or strong acids.
How long does it take to get a quote?
We will provide a quote within 24 hours after receiving your inquiry.
What are the common specifications of PVC waterstops?
Common widths are 200mm, 300mm, 400mm, etc., and the thickness is typically 4mm to 8mm. Specific dimensions can be selected according to the engineering design.
What is the main purpose of a PVC waterstop?
PVC waterstops are mainly used for waterproof sealing of concrete expansion joints, settlement joints, and construction joints, commonly found in underground structures, dams, tunnels, water tanks, and similar projects.
What precautions should be taken when storing and handling PVC waterstops?
They should be kept away from direct sunlight and heat sources, stored in a cool and dry place; during handling, avoid scratches from sharp objects and prevent twisting or deformation.
