Chemical processing buyers increasingly specify plastic sheets and boards instead of metal, wood or glass. Here is where they are used, why they work, and what to watch out for.
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 sheets and boards 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 thickness 0.5 mm to 50 mm; roll stock up to 30 m; textured, matte, gloss and embossed finishes. Materials most often specified are High Density Polyethylene, Polystyrene, Polypropylene, UHMWPE, and the choice between them changes stiffness, temperature resistance, chemical behaviour and price.
In the chemical processing sector the decision is usually driven by chemical resistance and temperature resistance, with purity as a secondary requirement. Typical end uses include hoses, valves, dosing pipework.
Typical values for a general purpose grade are listed below; filled, stabilised and speciality compounds will differ.
| Material | Density | Tensile strength | Service temperature |
|---|---|---|---|
| UHMWPE | 0.93-0.94 g/cm³ | 30-45 MPa | -150°C to 80°C |
| Polypropylene | 0.90-0.91 g/cm³ | 25-40 MPa | -10°C to 100°C |
| Polymethyl Methacrylate | 1.18 g/cm³ | 50-75 MPa | -40°C to 80°C |
Polyvinyl Chloride is frequently the default selection here: PVC can be formulated from rigid pipe compound to soft medical grade by changing plasticiser content.
In the chemical processing sector, these are the applications where this product has proven itself.
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.
Send this list to your supplier with the drawing and you will receive comparable quotations from every factory you contact.
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.
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 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.
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.
Share your specification and quantity with us and we will recommend the most cost effective material, tooling route and packing method for your market.
