Polyether Ether Ketone (PEEK) and Thermoplastic Elastomer (TPE / TPR) are the two most quoted options for medical plastic components 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 medical 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 tubing ID 0.5 mm to 25 mm; micro moulded parts below 0.1 g; gamma, ETO and steam sterilisation grades. Materials most often specified are Polyvinyl Chloride, Polypropylene, Polyurethane, 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 shade nets, 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 |
|---|---|---|---|
| Polyurethane | 1.05-1.25 g/cm³ | 25-60 MPa | -30°C to 90°C |
| Polycarbonate | 1.20 g/cm³ | 55-70 MPa | -40°C to 120°C |
| Polyether Ether Ketone | 1.32 g/cm³ | 90-100 MPa | -50°C to 250°C |
Polyether Ether Ketone is frequently the default selection here: PEEK replaces metal in the hottest and most chemically aggressive service conditions.
Polyether Ether Ketone grades offer retains strength at 250°C, while Thermoplastic Elastomer brings rubber-like softness with thermoplastic processing. For agriculture and horticulture service the difference shows up in impact strength 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.
Processing method drives both cost and performance, so it should be fixed early in the design.
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.
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.
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.
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.
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.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
