ASA

Rigid, UV and weather resistant. For parts that stay outdoors or work in warm air.

ASA is a rigid plastic that keeps its colour and strength in direct sun and rain, and it holds its shape in warm air up to the stated maximum working temperature. Use it for parts that stay outdoors, in sheds and garages, or near warm exhaust air within that limit.

Limits stated by Flantex

The temperature is the one each product’s use and safety instructions state. The tolerance is the general one of the Terms of Sale, and a product page may state its own.
Maximum working temperature	95 °C
Dimensional tolerance	±0.5%, lower limit ±0.2 mm

Where to use it

Good for

Parts that stay outdoors in direct sun and rain
Warm air up to the stated maximum working temperature
Parts that must stay stiff under a load
Contact with acids and alkalis

Not for

Air or surfaces hotter than the stated limit, such as stove and exhaust gases
Contact with some organic solvents, oils and greases
Pressurised systems, gas, fuel, food or drinking water
Parts that must bend or seal by flexing
