Performance Comparison between Silicone Connecting Wire And PVC Wire: How To Choose The Right Insulating Material?

In the application field of wires and cables, the choice of insulating materials directly determines the durability, safety and applicability of the product. Common insulating materials mainly include silicone and PVC, which have their own advantages in electrical performance, temperature resistance, and flexibility. With the increasing demand for high-performance cables, how to choose between silicone insulated wire and pvc insulated wire has become the focus of many engineering projects and manufacturing companies.

This article will analyze in detail the applicability of silicone and PVC wires in different scenarios, and by comparing two typical products-UL3512 200 ℃ 600V Silicon Electrical Wire and UL1032 90 ℃ 1000V or 1200V PVC Electrical Wire, to help you more comprehensively understand how to choose the right insulating material.

1. Silicone insulated wire: an ideal choice for high temperature and flexibility

Silicone insulated wire is widely used in home appliances, lighting, industrial equipment and new energy fields for its excellent high temperature resistance and excellent flexibility. High temperature silicone cable can work for a long time in a wide temperature range of -60℃ to 200℃, far exceeding the temperature tolerance range of general PVC wires.

In addition, the elasticity and softness of silicone make it more advantageous in narrow space wiring or environments that require frequent bending, such as electric vehicle battery connection cables (silicone battery cable), high-end electrical appliances internal wiring (silicone hook up wire), etc.

The main features of silicone wire include:

• Excellent heat resistance, suitable for high temperature working environment.

• Excellent cold resistance and aging resistance.

• Good insulation performance and dielectric strength.

• Environmentally friendly and halogen-free, low smoke and non-toxic when burning.

2. PVC insulated wire: general purpose and cost-effective

Compared with silicone insulated wire, PVC insulated wire (PVC insulated wire) has become the most widely used insulating material due to its economy and good processing performance. PVC has excellent flame retardancy, insulation and mechanical strength, and is the first choice for most medium and low temperature electrical systems.

PVC hook up wire (PVC wiring wire) is widely used in household appliances, lighting, electrical cabinets and other occasions. Its operating temperature generally does not exceed 90°C, and it is suitable for scenarios with low heat resistance requirements but cost sensitivity.

The main advantages of PVC insulated wire:

• Low material cost and high cost performance.

• Mature processing and molding technology, short delivery cycle.

• Good flame retardant performance, meeting most construction and industrial standards.

• The insulation layer is hard and wear-resistant.

3. Comparison of typical product performance

The following table lists the main parameters of UL3512 silicone wire and UL1032 PVC wire to help you intuitively understand the difference in applicability between the two:

As can be seen from the table, if your project needs to operate in high temperature and harsh environment, and has high requirements for flexibility, high temperature silicone cable, silicone hook up wire and silicone battery cable are ideal choices. If the working voltage is higher and the ambient temperature is lower, UL1032 PVC wire is more suitable for general industrial use due to its higher rated voltage and lower cost.

4. How to choose the right insulating material?

In actual selection, the following factors should be considered comprehensively:

Working temperature

If the wire needs to work in an environment above 90℃ for a long time, it is recommended to give priority to silicone insulated wire, such as silicone insulated wire or high temperature silicone cable.

Flexibility and bending radius

Silicone insulation material has outstanding flexibility and is suitable for spaces that require multiple bends or complex routing.

Withstand voltage and safety level

When the electrical system requires a high withstand voltage level, PVC insulated wire with medium and high rated voltage specifications, such as UL1032, can be considered.

Economical

For projects with limited budgets or no need for high temperature resistance, PVC insulated wire is still the preferred option.

Environmental protection requirements

If there is a clear requirement for halogen-free and low-smoke, silicone materials are more in line with environmental protection standards.

5. Summary

Silicone wire and PVC wire have their own advantages. In the scene of pursuing high temperature resistance, flexibility and environmental protection performance, silicone insulated wire, silicone hook up wire and silicone battery cable are undoubtedly the better choice; in general industrial and building wiring, economical and practical pvc insulated wire and pvc hook up wire are still widely used. Correctly understanding the performance characteristics of the two materials will help to scientifically select according to project requirements and ensure the safety and stability of the electrical system.
