In the chemical industry, plastic gratings are popular for their light weight, high strength, and excellent corrosion resistance. But what about temperature resistance? Can plastic gratings be used in environments where heat is regularly encountered?
The answer is: it depends on the type of resin used. Not all plastic gratings are the same. The resin largely determines whether a grating is suitable for high temperatures and aggressive chemicals
Plastic gratings, also known as glass fiber reinforced plastic (GRP) gratings, are constructed from a combination of fiberglass and resin. The resin acts as the binding agent that determines properties such as:
In industrial applications it is therefore crucial to choose the right type of resin.
| Resin type | Corrosion resistant | Temperature resistance | Courage | Price & benefits |
| Orthophone | Average | Average (~60℃) | Good | Most economical option, suitable for mild environments |
| Isophthalic | Good | Fairly good (~80℃) | Good | Excellent price-quality, standard in stock |
| Vinyl ester | Optimal | Best (~120℃) | Highest | Superior corrosion resistance, higher price |
Choosing the right resin type for the chemical industry depends on the conditions in which the grid will be used. Some guidelines:
You've come to the right place for all types of plastic gratings, tailored to your application. Isophthalic is our standard, but we also supply gratings with other resin types. Contact us for more information!
Yes, the temperatures depend on the type of resin. Vinyl ester is the most heat-resistant, up to 120°C.
We supply plastic gratings based on isophthalic polyester resin as standard, which we keep in stock. We can also supply plastic gratings with orthophthalic polyester resin or vinylester resin. Please feel free to contact us for more information.
Isophthalic polyester resin covers most applications. For extreme chemical or heat conditions, vinyl ester resin is more suitable.
