Low Density Polyethylene (LDPE) and Polyurethane (PU / TPU) are the two most quoted options for plastic cable insulation and jacketing in electronics and electrical projects. Both are widely available, but they behave very differently once they are in service.
Use it as a working checklist when you write your next enquiry.
This category covers a family of products rather than a single item. In practice a buyer defines plastic cable insulation and jacketing by three things: the base resin, the format or dimension, and the performance or certification level it has to meet. Typical options in this category include conductor 0.5 mm² to 400 mm²; rated 300/500 V to 0.6/1 kV; low smoke zero halogen options. Materials most often specified are Polyurethane, Polyvinyl Chloride, Thermoplastic Elastomer, Low Density Polyethylene, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the electronics and electrical sector the decision is usually driven by flame retardancy and dimensional stability, with EMI control as a secondary requirement. Typical end uses include switchgear panels, connectors, battery holders.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
| Low Density Polyethylene | 0.91-0.93 g/cm³ | 8-20 MPa | -50°C to 70°C |
| Polyvinyl Chloride | 1.38-1.45 g/cm³ | 40-55 MPa | -10°C to 60°C |
Low Density Polyethylene is frequently the default selection here: LDPE is the workhorse of flexible packaging because of its softness and sealing behaviour.
Low Density Polyethylene grades offer very flexible and soft, while Polyurethane brings outstanding abrasion and tear resistance. For electronics and electrical service the difference shows up in UV stability and in the long term behaviour under load.
The practical decision usually comes down to the service environment: temperature, chemical exposure and expected lifetime.
Beyond the base resin, most suppliers offer UV stabilised, food contact, flame retardant, anti-static and recycled content versions of the same product. Ask which additive package is included, because it is often the difference between a part that lasts three years and one that lasts ten.
Each step below has its own control points, and skipping one of them is where most defects start.
Secondary operations such as printing, welding, machining and assembly are often cheaper to do in the same factory, and they reduce the risk of mismatch between components.
These are the criteria that actually predict whether the part will perform in service.

A new tool typically takes 25 to 45 days depending on cavity count and complexity, followed by T1 samples within one week. Existing tools can usually start production within 10 to 15 days of order confirmation.
Yes. {mat1} is one of our regular materials for this item, and we can supply virgin, modified and certified grades with full traceability. Material certificates and test reports are issued per batch.
Colour is controlled with a masterbatch reference approved by the customer, and every production lot is checked against the approved sample under standard lighting before shipment.
Standard packing is export cartons on fumigation-free pallets, with custom labelling, barcode and retail packing available. We also handle consolidated containers and door to door delivery.
Standard production tolerance follows the relevant ISO or DIN tolerance class for the process; tighter tolerances are possible after machining or grinding, but they add cost. Define the tolerance only on the functional dimensions.
Our team supplies plastic cable insulation and jacketing to electronics and electrical customers worldwide, with samples, material certificates and full inspection reports available before mass production.
