VINYLGUARD
Frequently asked questions
Common questions about VINYLGUARD from 3G Electric.
What is the shrink ratio of VINYLGUARD PVC heat shrink tubing?
VINYLGUARD PVC heat shrink tubing has a shrink ratio of approximately 2:1. For example, tubing with a 0.63-inch inner diameter before shrinking reduces to 0.31 inches after shrinking, and a 3-inch inner diameter reduces to 1.5 inches. This ratio allows the tubing to fit snugly over components of varying sizes within the specified range.
What colors are available for VINYLGUARD heat shrink tubing?
VINYLGUARD heat shrink tubing is available in clear, black, and orange. Clear tubing is useful for applications where visual inspection of the underlying connection or component is needed. Black and orange options can be used for color-coding wires or cables for identification purposes in industrial installations.
What is the operating temperature range for VINYLGUARD PVC heat shrink tubing?
VINYLGUARD PVC heat shrink tubing is rated for continuous operation in a temperature range typically from -20°C to 105°C. This range is standard for PVC-based heat shrink materials and makes the tubing suitable for indoor and outdoor industrial environments where moderate thermal exposure occurs.
How is VINYLGUARD heat shrink tubing applied?
VINYLGUARD heat shrink tubing is applied using a standard heat gun or oven. The tubing is slipped over the component or cable before shrinking. When heated to approximately 100°C to 135°C, the tubing contracts uniformly to conform to the substrate. Ensure the tubing is not overheated to avoid damage. The tubing shrinks to approximately half its original diameter.
What lengths are VINYLGUARD heat shrink tubing supplied in?
VINYLGUARD heat shrink tubing is supplied in continuous lengths, typically 25 feet or 50 feet per coil, depending on the SKU. For example, SKU 33VH20 is a 25-foot length, while SKU 33VH29 is a 50-foot length. Users can cut the tubing to the desired length for each application.
Is VINYLGUARD heat shrink tubing resistant to chemicals?
Yes, VINYLGUARD heat shrink tubing is formulated to be chemical-resistant. The PVC material provides resistance to a range of chemicals, oils, and solvents commonly encountered in industrial settings. However, specific chemical compatibility should be verified for extreme or concentrated exposures, as PVC may degrade in certain aggressive environments.
