Flame retardant heat shrink tube from Volsun Electronics Technology Co., Ltd. is manufactured from polyolefin compound designed to shrink at 125°C and provide mechanical and environmental protection to wire joints. The tube has a 2:1 shrink ratio, meaning it reduces its diameter by half when heated, enabling snug fit over connectors and splices. It is supplied in continuous lengths, with inner diameters ranging from 3.2 mm to 25.4 mm before shrinking.
The material formulation includes flame-retardant additives such as aluminium trihydrate or brominated compounds to meet UL 224 and IEC 60684-2 standards. The tubing exhibits chemical resistance to fuels, oils, and solvents, and maintains flexibility after shrinkage. It is not reinforced with fabric or mesh, making it suitable for lightweight applications where flexibility is critical over structural rigidity.
This product is used in automotive wiring harnesses, aerospace connectors, and industrial control panels where fire safety and insulation integrity are mandatory. Buyers include Tier 2 automotive suppliers, OEMs in renewable energy systems, and maintenance contractors. Trade terms are typically FOB Suzhou or CIF port of destination, with packaging in 100-meter reels on plastic spools. Minimum order quantities are negotiable but typically start at 500 meters per size.

Verify the tubing's flame retardant certification matches your market requirements, such as UL 224 or IEC 60684-2. Request test reports for shrink temperature, tensile strength, and flammability. Do not rely on generic claims like 'flame retardant' without a standard reference. Confirm the material does not contain restricted substances under RoHS or REACH if exporting to the EU.
Confirm the Incoterms, shipping method, and lead time. Standard terms are FOB Suzhou, with lead times of 2 - 3 weeks for standard sizes and 4 - 6 weeks for custom diameters. Payment terms are typically 30% advance, 70% against BL copy. Ask for packaging details: reels must be sealed in anti-static bags if shipping to electronics manufacturers.
Perform incoming inspection for diameter consistency, wall thickness uniformity, and shrink performance. Use a micrometer on 5 points per reel, both before and after heating. Check for cracks, bubbles, or uneven shrinkage. Retain a sample from each shipment for future quality audits. Request a certificate of conformity with each delivery.
