What is the temperature range of polyethylene board?

Polyethylene sheets can be used in a wide temperature range (from -180 degrees Celsius to +250 degrees Celsius). Basically resistant to all chemicals except some fluorides and alkaline metals. Excellent mechanical properties including ageing resistance especially for bending and wobbling applications. Outstanding flame retardancy (conforms to ASTM-D635 and D470 test procedures, is regulated as flame retardant in air. Excellent insulating properties (regardless of frequency and temperature) Very low water absorption, and is self-lubricating and non-stick and a series of unique properties.
