ABS

Rigid and impact resistant. For parts that stay indoors or work in warm air, out of direct sun.

ABS is a rigid plastic that takes knocks and holds its shape in warm air up to the stated maximum working temperature. Use it for parts that stay indoors, in workshops and machine enclosures, or near warm exhaust air within that limit. In direct sun it fades and turns brittle, so for outdoor parts use ASA.

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	80 °C
Dimensional tolerance	±0.5%, lower limit ±0.2 mm

Where to use it

Good for

Parts that stay indoors, out of direct sun
Warm air up to the stated maximum working temperature
Parts that must stay stiff under a load
Contact with acids and alkalis

Not for

Direct sun and weather, which fade ABS and make it brittle
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
