Product Overview

Yozonetech's medium- and heavy-wall adhesive-lined heat-shrink products are designed for applications where a thin-wall sleeve is insufficient and the assembly requires stronger mechanical protection, electrical insulation, moisture sealing and environmental protection. The source range includes 3:1 medium-wall products, heavy-wall 3:1 products, flame-retardant constructions and a CATV-oriented variable heat-shrink product.

The adhesive liner melts and flows during installation to fill irregularities and provide environmental sealing around cable splices, terminations, connectors and related components. Product selection should be based on the assembly diameter before and after recovery, required wall thickness, operating temperature, flame-retardancy requirement, cable environment and the required level of mechanical protection.

Important: the source itself distinguishes products that are flame-retardant from products explicitly marked 'not flame-retardant'. Those distinctions are retained below rather than generalized across the whole product family.

Product Selection Framework

Selection factor How to use it
Retardador de chama Choose a family explicitly identified as flame retardant when the application requires it. Do not assume NF products have the same flame rating.
Wall construction Medium-wall products balance flexibility and protection; heavy-wall products are intended for higher mechanical and environmental protection.
Shrink ratio SBRSM, SBRSW, SBRSM-NF, SBRSW-NF and SBRSTV shown here use a 3:1 ratio.
Adhesive sealing The adhesive liner is intended to seal against moisture, contaminants and environmental exposure. Tubing without adhesive is noted as available for selected families.
Cable diameter Select the expanded ID so the tubing can be installed over the assembly, then verify the recovered ID and recovered wall against the final geometry.
Operating temperature Most products in this group are listed at -45°C to +125°C; SBRSW-NF is listed at -45°C to +110°C and SBRSTV at -45°C to +110°C.
Installation temperature Most source pages specify 125°C full shrink temperature; follow the exact product page and controlled installation procedure.

SBRSM — Flame Retardant Medium Wall Adhesive-Lined Heat Shrink Tubing

SBRSM is a 3:1 flame-retardant medium-wall adhesive-lined heat-shrink tubing for low-voltage electrical and mechanical applications where lighter weight and greater flexibility are important.

Application Guidance

Product Source-positioned application / role
SBRSM Low-voltage electrical and mechanical applications where lighter weight, flexibility, splice sealing and flame retardancy are required.
SBRSW Electrical splices and terminations requiring heavy-wall mechanical protection, sealing and flame retardancy.
SBRSM-NF Low-voltage electrical/mechanical applications needing medium-wall adhesive sealing and mechanical protection, where flame retardancy is not required.
SBRSW-NF Severe mechanical, underground/submersible and direct-burial cable-joint applications; 1 kV, 90°C continuous-use rating is stated in the source.
SBRSTV CATV splice and connector protection, particularly where weathering, moisture and contamination resistance are important.

Installation & Purchasing Notes

  • Verify the assembly's maximum and minimum diameter before selecting the expanded ID. A 3:1 ratio does not mean every size can replace every neighboring size.
  • Allow sufficient overlap beyond the splice, termination or joint so the adhesive can form a continuous environmental seal.
  • Use controlled heating rather than excessive localized heating. The source specifies 125°C full-shrink temperature for these families.
  • For flame-retardant projects, use the exact flame-retardant model specified in the source. SBRSM-NF and SBRSW-NF are explicitly described as not flame-retardant.
  • Check the recovered wall thickness when mechanical protection is critical; medium-wall and heavy-wall products are not interchangeable simply because their diameters overlap.
  • Confirm whether adhesive lining is required. The source notes that tubing without adhesive is available upon request for selected families.
  • For underground, submersible or direct-burial installations, confirm the environmental and cable-system requirements in addition to the tubing specification.
  • Verify the operating-temperature rating of the exact model. SBRSM/SBRSW/SBRSM-NF are listed to +125°C, while SBRSW-NF and SBRSTV are listed to +110°C.
  • Confirm RoHS and other compliance requirements against the controlled current specification before publication or certification submission.
  • Use the original controlled datasheet for final purchasing and engineering release if any scanned-table character or decimal is unclear.

Frequently Asked Questions

What products are covered by DOC 02?

SBRSM, SBRSW, SBRSM-NF, SBRSW-NF and SBRSTV, covering medium-wall, heavy-wall and CATV-oriented adhesive-lined heat-shrink constructions.

Are all products in DOC 02 flame-retardant?

No. The source explicitly identifies SBRSM and SBRSW as flame-retardant, SBRSTV as flame-retardant, while SBRSM-NF and SBRSW-NF are explicitly described as not flame-retardant.

What is the common shrink ratio?

The products covered here are presented with a 3:1 shrink ratio.

What is the main advantage of adhesive lining?

The thermoplastic adhesive liner flows during heating to improve environmental sealing and insulation around splices, terminations and joints.

What is the operating temperature of SBRSM?

The source lists continuous operation from -45°C to +125°C, with full shrink temperature of 125°C.

Which product is intended for heavier mechanical protection?

SBRSW and SBRSW-NF are heavy-wall constructions and provide substantially thicker recovered walls than the medium-wall families.

Which product is associated with CATV?

SBRSTV is specifically described as a medium-wall adhesive-lined variable heat-shrink tubing that established a CATV industry standard for splice and connector protection.

Can the products be supplied without adhesive?

The source specifically notes that tubing without adhesive is available upon request for the SBRSM, SBRSW, SBRSM-NF and SBRSW-NF families shown here.

What should I use for direct-burial or submersible installations?

SBRSW-NF is specifically described for severe mechanical requirements including submersible and direct-burial installations, but the complete cable-system specification should still be checked.

How should I choose the size?

Source & Technical Data Note

Source file: “English version - Heat shrink tube - Yozonetech company profile.pdf”. DOC 02 uses the product content corresponding to PDF pages 19–23 and printed catalogue pages A29–A38. Images are excluded.

The source is a scanned/image-based catalogue. OCR transcription can affect symbols such as ±, ≥, decimal points and superscripts. For this reason, the original PDF and current controlled manufacturer datasheet remain the final reference for critical engineering, quotation, certification and production-release data.
