Thermoplastic Elastomer (TPE / TPR) and Glass Filled Nylon (PA66-GF30) are the two most quoted options for automotive plastic components in agriculture and horticulture projects. Both are widely available, but they behave very differently once they are in service.
This guide is written for engineers, purchasers and project managers who need a practical answer, not a resin data sheet.
This category covers a family of products rather than a single item. In practice a buyer defines automotive plastic components 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 class A painted surfaces; tolerance down to ±0.05 mm; multi material assemblies. Materials most often specified are Polypropylene, Thermoplastic Elastomer, Polyoxymethylene, Polyamide, 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 silage wrap, shade nets, drip irrigation lines.
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 |
|---|---|---|---|
| PC/ABS Alloy | 1.13-1.15 g/cm³ | 45-60 MPa | -30°C to 110°C |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Glass Filled Nylon | 1.36-1.38 g/cm³ | 130-190 MPa | -40°C to 150°C |
Thermoplastic Elastomer is frequently the default selection here: TPE removes the vulcanisation step, so soft parts come off the press ready to pack.
Thermoplastic Elastomer grades offer rubber-like softness with thermoplastic processing, while Glass Filled Nylon brings two to three times the stiffness of unfilled nylon. For agriculture and horticulture service the difference shows up in chemical resistance and in the long term behaviour under load.
In short: choose the first option when stiffness, heat and dimensional stability dominate; choose the second when impact, cost and processing speed matter more.
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.
The route below is the one most factories use for this type of part.
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.

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.
We can provide ISO 9001 quality system documentation, material certificates, RoHS and REACH statements, and where applicable food contact, flame retardancy or drinking water approvals. Tell us your target market and we will match the document set.
For standard sizes and colours the minimum is usually one pallet or one production run; for custom tooling the economic minimum depends on the tooling cost amortised over the expected volume. Send us your annual volume and we will calculate the break even point.
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.
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.
If you are planning a new agriculture and horticulture project, send us your drawing, annual volume and target properties, and we will come back with a material proposal, a tooling plan and a budget quotation.
