WILLELE Heat Shrink type Connector Production Workflow

Ensuring Precision and Quality at Every Step for Custom Wire Harness Solutions

01

Material Selection

High-quality, eco-friendly raw materials are carefully chosen to meet safety and performance standards.

02

Extrusion Process

Materials are heated and extruded through a die to form tubing, ensuring consistent thickness and diameter.

03

Expansion

Tubing is expanded using heat and compressed air, then cooled to set the expanded form.

04

Cross-Linking

Using electron beam or chemical methods, the tubing undergoes cross-linking to enhance strength and durability.

05

Cutting and Sizing

Cross-linked tubing is cut into specified lengths, ensuring uniformity and consistency.

06

Quality Control and Packaging

Tubing undergoes rigorous quality checks before being packaged and labeled for shipment.

How to use Heat Shrink Type Connector

1. Cut the heat shrink tubing to the appropriate length as needed.

2. Put the heat shrink tubing onto the data cable.

3. Evenly heat using a hot air gun.

4. Until the heat shrink tubing is fully shrunk.

What you need to know about Heat Shrink Tubing

What is Heat Shrink Tubing?

Heat shrink tubing is a specialized plastic tube that contracts radially when exposed to heat, tightly conforming to the shape of the object it covers. This thermoplastic material, also known as electrical shrink wrap or cable shrink sleeve, is primarily used to insulate and protect electrical components from external factors such as moisture, abrasion, and environmental contaminants. Available in various sizes and shrink ratios, typically 2:1 or 3:1, the tubing can reduce to half or even a third of its original diameter when heated. Its versatility and protective properties make it an essential component in electrical setups across multiple industries, including automotive, aerospace, and consumer electronics. 

Key Properties of Heat Shrink Tubes

Heat shrinkable tubes with flame-resistant properties are typically made from radiation cross-linked polyolefin, PVDF, PVC, or silicone rubber, with zero halogen options available for low smoke generation. These materials offer a standard shrink ratio of 2:1 and can operate within a temperature range of -55°C to +125°C. The dielectric strength varies depending on the material used, with PVC offering 2,000 V/mil, PVDF providing 900 V/mil, and polyolefin delivering 500 V/mil. Some variants, such as heat-resistant silicone tubes, can withstand temperatures up to 200°C.

Protection Features of Heat Shrink Tubing

Flame-resistant heat shrinkable tubes offer a range of protective features beyond their fire-retardant properties. These tubes provide excellent resistance to acids and alkalis, making them suitable for use in harsh chemical environments. Some variants also offer UV resistance, enhancing their durability in outdoor applications. The tubes provide mechanical protection against cuts and abrasion, ensuring the integrity of enclosed wires and components.For applications requiring additional protection, adhesive-coated versions are available, offering waterproof properties to safeguard against moisture ingress. This combination of chemical resistance, mechanical protection, and optional waterproofing makes flame-resistant heat shrinkable tubes a versatile solution for various industrial and electrical applications.

Safety Standards

Flame-resistant heat shrinkable tubes adhere to rigorous safety standards, ensuring their reliability in critical applications. These products often meet the VW-1 flame rating, which demonstrates their ability to prevent flame spread. Many variants possess self-extinguishing capabilities, enhancing their fire safety profile. For specific types, UL and CSA certifications are available, validating their compliance with industry-recognized safety benchmarks.In specialized sectors like mining, certain flame-resistant heat shrinkable tubes have obtained MSHA approval, certifying their suitability for use in potentially hazardous underground environments. This comprehensive adherence to safety standards underscores the tubes’ importance in maintaining operational safety across various industries.

Materials for Flame-Resistant Tubes

Flame-resistant heat shrinkable tubes are primarily made from advanced polymers engineered for fire safety and durability. The most common materials include crosslinked polyolefin, polyvinyl chloride (PVC), polyvinylidene fluoride (PVDF), and silicone rubber. Crosslinked polyolefin is widely used due to its excellent plasticity, stable physical and chemical properties, and self-extinguishing capabilities. PVDF offers superior flame retardancy and chemical resistance, while silicone rubber provides high flexibility and temperature resistance up to 390°F.

Types of Heat Shrink Tubing Materials

  • Polyolefin: The most common and versatile material, offering excellent electrical insulation, chemical resistance, and flexibility. It’s available in shrink ratios up to 4:1 and performs well in temperatures from -55°C to +135°C.
  • PVC (Polyvinyl Chloride): Cost-effective and available in many colors, PVC tubing provides good insulation and moisture resistance.
  • Fluoropolymers (PTFE, FEP): Highly resistant to chemicals and extreme temperatures, with low friction coefficients. FEP shrinks at lower temperatures than PTFE.
  • Elastomeric: Flexible and resistant to abrasion and hazardous liquids, making it ideal for industrial environments.
  • PVDF (Polyvinylidene fluoride): Offers high resistance to flame, corrosive chemicals, and industrial fuels
