Corrugated Tubing: Superior Flexibility and Protection
Made from various plastic materials, including Polyethylene, Polyamide or Nylon, and Polypropylene. （Further reading: What is convoluted tubing?） Among other plastic materials, Polypropylene convoluted tubing is commonly selected for engine surroundings due to its high melting point, excellent flame resistance, and low thermal conductivity. With the high temperatures around the engine, Polypropylene convoluted tubing ensures the protection of surrounding components, prevents fire hazards, and complies with FMVSS 302. Additionally, Polypropylene convoluted tubing has a higher hardness, protecting wires against vibrations and abrasion during vehicle operation.
Heat Shrink Tubing: Effective Enclosure and Protection
Heat shrink tubing has a unique characteristic where its diameter shrinks when subjected to heat, allowing it to encapsulate wires or cable bundles regardless of their shape tightly. It provides insulation, flame resistance, and weather resistance for enhanced protection. Compliant with UL 224, YDPU2, and CUL YDPU8 certification due to the requirement for heat application during installation, it is typically not widely used for large-scale applications. Typical applications include wire terminations or end caps for other tubing. For sealing purposes, adhesive-lined heat shrink tubing can be chosen, as it effectively seals out external factors such as moisture or dust. It has wide applications in waterproofing, leak prevention, and corrosion protection for repairs.
Fiberglass Sleeving: High-Temperature Resistance and Protection
Fiberglass sleeving is a representative material among high-temperature insulation tubing, capable of withstanding temperatures up to 500 ℃. Conforms to flame test UZIQ2 and UZFT2 insulation test in UL 1441. It possesses flame retardant and self-extinguishing properties, making it highly suitable for applications in high-temperature environments, particularly within automotive interiors. It effectively protects against hazards and reduces the risk of incidents. Additionally, fiberglass sleeving offers flexibility, allowing for easier installation. Apart from the automotive sector, it finds widespread applications in aerospace, electronics, industrial machinery, and other industries. It plays a crucial role in these fields. （Further reading: Practical Guide to Fiberglass Sleeving）
Self-wrapping Woven Sleeving: Flexible Installation and Maintenance
Made of polyester monofilaments and multifilaments, self-wrapping woven sleeving possesses characteristics such as flame resistance（Compliant with UZIQ2）, abrasion resistance（ Compliant with ISO 6722-1:2011）, flexibility, and dust protection. Its self-wrapping design allows for both protection and cable management, offering easy and fast installation, as well as convenient modification, maintenance, and inspection of wire harnesses. Widely applications in communication, high-speed rail, automotive, automation equipment, and instrument circuits, especially suitable for use with irregularly shaped wire bundles. （Further reading: Learn more about the characteristics and sizes of self-wrapping woven sleeving）
Extruded PVC Tubing: Cost-effective Comprehensive Protection
Extruded PVC tubing offers characteristics such as voltage resistance, weather resistance, high and low-temperature resistance, flexibility, and resistance to gasoline. Its excellent insulation properties can be widely used in automotive wire harnesses, motors, and wire connections, providing insulation and protection. GoodGi's extruded PVC tubing complies with UL and CSA standards, as well as RoHS and REACH environmental standards, and meets automotive fire protection regulations FMVSS302. This ensures the quality and safety of the product, making it a widely chosen insulation tubing in the automotive industry. （Further reading: Chemical Compatibility Chart for PVC Tubing）
PET Expandable Braided Sleeving: Excellent Breathability and Heat Dissipation
PET Expandable Braided Sleeving is highly flexible and can expand to approximately twice its diameter, making it suitable for irregularly shaped wire harnesses. In addition to providing protection, it also facilitates wire organization. Made from PET material, it offers flame resistance（Compliant with UZIQ2）, chemical corrosion resistance, excellent heat dissipation, and breathability. It possesses remarkable characteristics such as flexibility, impact resistance, and abrasion resistance（ Compliant with ISO 6722-1:2011）.
