Choosing the right polymer grade for cable insulation is essential for electrical performance, durability, and safety. Whether you're producing power cables, fiber optics, or control wires, your insulation material must be weather-resistant, flexible, and capable of withstanding voltage stress.

At Polymer in Stock, we offer high-quality polymer grades that are specifically suited for cable insulation and jacketing—available in virgin, offgrade, and recycled forms for every budget and need.

Why Polymer Choice Matters in Cable Insulation

The insulation layer of a cable is responsible for:

• Preventing short circuits

• Withstanding high temperatures

• Resisting moisture and chemicals

• Maintaining flexibility over time

Using the wrong polymer can lead to cracking, signal interference, and even fire hazards. Let’s explore the best-performing polymer grades for cable manufacturers.

1. LDPE (Low-Density Polyethylene)

✅ Best For: Flexible cable insulation, fiber optic protection

LDPE is known for its softness and moisture resistance. It's widely used in:

• Communication cable sheaths

• Coaxial cables

• Instrumentation cables

👉 Check out our Recycled LDPE Collection for cost-effective insulation materials.

2. HDPE (High-Density Polyethylene)

✅ Best For: Rugged outdoor and industrial cables

HDPE is tougher and has excellent electrical properties. It’s perfect for:

• Underground cables

• Outdoor telecom cables

• High-voltage applications

Visit our HDPE Offgrade Options for reliable performance and savings.

3. EVA (Ethylene-Vinyl Acetate)

✅ Best For: Heat-resistant, flexible insulation

EVA has outstanding low-temperature properties and is used in:

• Automotive wiring

• Flexible cord insulation

• Flame-retardant applications

4. XLPE (Cross-linked Polyethylene)

✅ Best For: High-voltage power cables

Though technically not a pure polymer grade but a processed form, XLPE is created by cross-linking LDPE or HDPE. It's used in:

• Power transmission cables

• Subsea and underground cables

Note: We supply base HDPE/LDPE grades ideal for XLPE manufacturing processes.

5. PVC (Polyvinyl Chloride)

✅ Best For: General-purpose cable sheathing

PVC is one of the most versatile insulation materials:

• Affordable

• Flame-retardant

• Resistant to abrasion and UV
