Product Description
Engineered for demanding industrial applications, our large diameter PVC heat shrinkable tubings deliver exceptional performance in complex environments. Manufactured from premium-grade polyvinyl chloride, these tubings present a smooth, uniform surface before heating, transitioning into a rigid, tightly conformed protective shield once shrunk. The material inherently possesses excellent flame retardancy, superior electrical insulation, and outstanding weather resistance, ensuring long-term stability even when exposed to harsh outdoor climates, UV radiation, or chemically aggressive industrial settings. The tactile flexibility of the un-shrunk tubing makes routing over complex wire structures straightforward, while the post-shrink rigidity locks components firmly in place.
◆ Function：
1. wire coat and insulation.
2. make the joint of terminal block and wire insulated.
3. divide the colors.
4. water-proof.
5. protection and insulation of insistors and electrical capacitors.
◆ Standard color : black, white, red, blue, yellow, green, brown, grey, orange and purple.
Beyond basic functionality, these tubings are extensively utilized across multiple sectors, including heavy-duty power distribution, intricate wiring harness management, automotive electrical systems, and marine equipment maintenance. The physical thickness of the recovered wall provides a reassuring, durable barrier that guarantees mechanical defense against abrasion, friction, and impact, while the precise chemical formulation prevents cracking, splitting, or degrading during the thermal contraction process. By offering this reliable, multi-layered barrier, the tubing actively extends the operational lifespan of critical electrical networks, reducing maintenance frequency and associated downtime.
Selecting the correct diameter and thickness is crucial for achieving an optimal seal and maximum protective efficacy in any electrical or structural application. The following data sheet outlines the exact parameters for our large diameter tubings, detailing both the "as supplied" dimensions and the "after shrinking" specifications. Our standard shrinkage ratio ensures a predictable, uniform, and concentric reduction, allowing the tubing to tightly grip irregular shapes, bulky connectors, and multi-wire splices without leaving vulnerable air voids. When evaluating the sizing chart for your specific cables, ensure the supplied inner diameter (I.D.) easily slides over the largest component or connector body. Concurrently, verify that the fully recovered diameter (D1) is slightly smaller than the underlying wire or substrate to guarantee a snug, immovable, and moisture-resistant fit. Proper dimension selection directly influences the dielectric strength and mechanical integrity of the final assembly, safeguarding against environmental ingress and electrical tracking.

Time is a critical factor in large-scale assembly operations and field installations. These PVC tubings are engineered for a rapid, uniform, and highly controlled thermal response. When subjected to standard heating tools, such as industrial heat guns, infrared heaters, or automated shrink tunnels, the material contracts swiftly and evenly around the substrate. Operators will notice the distinct absence of acrid odors typically associated with processing inferior plastics. Instead, the tubing shrinks smoothly without bubbling, blistering, or localized scorching, significantly accelerating production line efficiency and reducing manual handling time. This predictable thermal behavior ensures that even complex, multi-branched harnesses can be insulated rapidly without risking thermal damage to the underlying sensitive electronic components.
Consistency across large-volume procurement is non-negotiable for industrial applications. Every production batch undergoes a stringent 100% factory inspection protocol before dispatch. Our technicians meticulously measure wall thickness consistency, concentricity, longitudinal shrinkage limits, and thermal stability to ensure absolute uniformity from the first meter to the last roll. Backed by comprehensive international compliance standards including ISO and SGS certifications, our production facilities guarantee that every shipment meets the exacting safety, environmental, and performance criteria required by global project managers. This rigorous testing regimen eliminates the risk of field failures caused by insulation breakdown.
