INSULTAB

INSULTAB is a brand of heat shrink tubing products, primarily serving industrial, commercial, and maintenance applications where electrical insulation, mechanical protection, and environmental sealing are required. The product line includes a range of tubing types differentiated by material composition, shrink ratio, operating temperature range, and resistance properties. Common materials used across the INSULTAB catalog include polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), and specialty formulations for food-grade, fuel- and oil-resistant, and severe outdoor environments. The tubing is supplied in various inner diameters before shrinking—from 0.09 inches to 2 inches—and after shrinking diameters as small as 0.05 inches, with shrink ratios typically at 2:1. Lengths range from 5-foot packs to 200-foot rolls, depending on the SKU. INSULTAB heat shrink tubing is used for insulating electrical connections, bundling wires, protecting cables from abrasion and chemicals, and providing strain relief. The brand does not appear to be associated with a single manufacturer; rather, it is a label applied to a broad selection of tubing sourced to meet specific performance criteria such as chemical resistance (e.g., PVC tubing rated for exposure to oils, fuels, and mild acids), food contact compliance (food-grade tubing meeting FDA or similar standards), and UV/weather resistance (severe outdoor environment tubing). 3G Electric stocks over 130 SKUs of INSULTAB heat shrink tubing, covering clear and black colors, multiple wall thicknesses, and various packaging configurations. The inventory includes standard PVC tubing for general-purpose insulation, PVDF tubing for higher-temperature and chemical-exposure applications, and specialized variants like fuel- and oil-resistant tubing for automotive or hydraulic systems. Each SKU is accompanied by datasheets that specify physical properties such as tensile strength, dielectric strength, operating temperature range (typically -55°C to +135°C for PVC, and up to +175°C for PVDF), and shrink temperature. 3G Electric provides logistics support for global shipping, including bulk orders and custom cut lengths, with technical documentation available for procurement and engineering review.

Common Applications

  • Electrical insulation — INSULTAB PVC heat shrink tubing (e.g., HS-105 series) for insulating wire splices and terminals in control panels.
  • Food processing equipment — INSULTAB food-grade heat shrink tubing (e.g., HS-614-1/2) for covering sensors and fittings in washdown areas.
  • Automotive fuel systems — INSULTAB fuel- and oil-resistant tubing (e.g., HS-VTN series) for protecting wiring near engines and fuel lines.
  • Chemical plant wiring — INSULTAB PVDF heat shrink tubing (e.g., HSK-600 series) for cable protection in corrosive chemical environments.
  • Outdoor cable splicing — INSULTAB severe outdoor environment tubing (e.g., HSN-100 series) for sealing and insulating underground or aerial cable joints.
  • Abrasion protection — INSULTAB transparent PVDF tubing (e.g., HSK-600-5/8) for bundling wires in high-vibration machinery.

Frequently asked questions

Common questions about INSULTAB from 3G Electric.

What materials are used in INSULTAB heat shrink tubing?

INSULTAB heat shrink tubing is available in several materials, primarily PVC (polyvinyl chloride) and PVDF (polyvinylidene fluoride). PVC tubing is used for general-purpose insulation, offering good chemical resistance and flexibility. PVDF tubing provides higher temperature resistance (up to +175°C) and superior abrasion and chemical resistance. Some SKUs are also formulated for specific environments, such as food-grade tubing (meeting FDA requirements) and fuel- and oil-resistant tubing (suitable for hydrocarbon exposure).

What shrink ratios are available for INSULTAB tubing?

INSULTAB heat shrink tubing is commonly supplied with a 2:1 shrink ratio, meaning the tubing shrinks to half its original inner diameter when heated. For example, a tubing with a 0.5-inch inner diameter before shrinking will reduce to 0.25 inches after shrinking. This ratio is standard across most SKUs, including PVC, PVDF, and specialty types. Some products may have different ratios, but the 2:1 ratio is the most prevalent in the catalog.

What is the operating temperature range for INSULTAB PVC heat shrink tubing?

INSULTAB PVC heat shrink tubing typically has an operating temperature range of -55°C to +135°C. This range covers most industrial and commercial applications, including electrical insulation and cable bundling. The exact temperature limits may vary slightly by SKU, so it is recommended to consult the datasheet for the specific part number. PVDF tubing, such as the HSK-600 series, can operate at higher temperatures, up to +175°C.

Is INSULTAB heat shrink tubing available in food-grade versions?

Yes, INSULTAB offers food-grade heat shrink tubing, such as the HS-614-1/2 Blk 100 SKU. This tubing is designed for applications where contact with food or potable water is possible, and it meets relevant food safety standards. The food-grade tubing is typically black and made from a material that resists degradation from cleaning agents and food acids. It is suitable for use in food processing equipment, beverage dispensing systems, and similar environments.

What lengths and packaging options are available for INSULTAB tubing?

INSULTAB heat shrink tubing is supplied in various lengths and packaging configurations. Common lengths include 5-foot packs (often sold as 5-piece kits), 10-foot lengths, 50-foot rolls, and 200-foot rolls. Some SKUs are packaged as multi-piece kits (e.g., 5-pack or 48-pack) for smaller jobs. The packaging is typically spooled or coiled for easy dispensing. 3G Electric can provide bulk quantities and custom cut lengths upon request.

Can INSULTAB heat shrink tubing be used outdoors?

Yes, INSULTAB offers tubing specifically designed for severe outdoor environments, such as the HSN-100 1-1/2 Blk 50 SKU. This tubing is formulated to resist UV radiation, moisture, and temperature extremes, making it suitable for outdoor electrical connections, cable splicing, and equipment protection. It is typically black and has a thicker wall for added durability. For general outdoor use, standard PVC tubing may also be acceptable, but the severe outdoor grade provides enhanced weather resistance.
