Indeed, it is feasible to use Astral Aquarius at temperatures around 10-1°C. The normal temperature range of uPVC compound material is typically between 23°C to 60°C. As the temperature drops below 23°C, uPVC, like other thermoplastic materials, becomes more brittle. Consequently, its impact properties are diminished at lower temperatures. However, the hydrostatic strength of the material remains unaffected, enabling its use at lower temperatures. Nonetheless, careful and thorough engineering design considerations are necessary when operating at such low temperatures to mitigate water hammer and impact-related concerns effectively.
