Low Density Polyethylene (LDPE) and High Density Polyethylene (HDPE) are the two most quoted options for plastic cable insulation and jacketing in agriculture and horticulture projects. Both are widely available, but they behave very differently once they are in service.
Everything here can be checked on a real sample before you commit to a production order.
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 rated 300/500 V to 0.6/1 kV; insulation wall 0.4 to 3.0 mm; flexible and rigid constructions. Materials most often specified are Low Density Polyethylene, Polyvinyl Chloride, High Density Polyethylene, Thermoplastic Elastomer, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the agriculture and horticulture sector the decision is usually driven by UV stabilisation and tear strength, with chemical resistance to fertilisers as a secondary requirement. Typical end uses include mulch film, drip irrigation lines, silage wrap.
These figures are typical for commercial grades and should be confirmed against the supplier's certificate for your specific lot.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| High Density Polyethylene | 0.94-0.97 g/cm³ | 20-32 MPa | -50°C to 80°C |
| Polyvinyl Chloride | 1.38-1.45 g/cm³ | 40-55 MPa | -10°C to 60°C |
| Low Density Polyethylene | 0.91-0.93 g/cm³ | 8-20 MPa | -50°C to 70°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 High Density Polyethylene brings high impact strength even at low temperature. For agriculture and horticulture service the difference shows up in impact strength and in the long term behaviour under load.
Both materials can be validated quickly with a small sample run, which is the cheapest way to settle the argument for your own application.
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.
Work through these points in order and most specification mistakes disappear.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
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.
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.
Yes. Standard samples are normally free of charge and shipped within three working days; custom samples are charged at cost and credited against the first production order.
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.
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.
Our team supplies plastic cable insulation and jacketing to agriculture and horticulture customers worldwide, with samples, material certificates and full inspection reports available before mass production.
