Why the high MOQ for PTFE material wires and cables?

The high minimum order quantity for PTFE material wires and cables can be attributed to several reasons.

1. Specialized Material: PTFE is a specialized and high-performance material with exceptional electrical insulation, heat resistance, chemical resistance, and moisture resistance properties. This makes PTFE cables suitable for demanding applications in industries like aerospace, telecommunications, and medical devices.

2. Complex Manufacturing Process: PTFE cables require a complex manufacturing process and specialized equipment. The production costs are generally higher compared to standard materials. To ensure efficient utilization of production facilities and resources, manufacturers often require customers to meet a higher minimum order quantity.

3. Limited Availability of Raw Materials: PTFE raw materials are sourced from a small number of suppliers. This limited availability can drive up costs and necessitate larger orders to justify the production and procurement expenses.

4. Customization Requirements: PTFE wires and cables often require customization based on specific requirements such as insulation thickness, conductor size, and jacket material. Customizing smaller quantities can be time-consuming, inefficient, and costly for manufacturers. Therefore, they prefer higher minimum order quantities to streamline production and achieve economies of scale.

In conclusion, the unique properties of PTFE, coupled with complex manufacturing processes, limited availability of raw materials, and customization requirements, contribute to the higher minimum order quantities for PTFE wires and cables.

What’s the difference between silicone and teflon material ?

Silicone and teflon are two types of non-stick materials that are used in a variety of applications. Although they have similar properties, they are different in terms of composition and uses.

Silicone is a synthetic rubber-like material composed of silicon, oxygen, carbon, and hydrogen. It is flexible, heat-resistant, and waterproof, and can withstand temperatures ranging from -40°F to 500°F (-40°C to 260°C). Silicone is used in kitchenware such as baking mats, baking pans, and cooking utensils due to its non-stick properties and ability to withstand high temperatures.

On the other hand, Teflon is a brand name for a type of fluoropolymer comprised of molecules of carbon and fluorine. It is known for its excellent non-stick properties and is used as a coating on cooking appliances, non-stick cookware and bakeware, and even in medical applications due to its biocompatibility. Teflon can withstand high temperatures and is chemically inert, which means it doesn’t react with other substances.

In summary, while silicone is flexible and heat-resistant, teflon is known for its excellent non-stick properties and chemical inertness. Both materials are commonly used in cooking and baking applications.
