Are plastic torpedo levels resistant to cracking or warping when exposed to extreme temperatures?

Plastic torpedo levels vary in their resistance to cracking or warping when exposed to extreme temperatures, and this largely depends on the type of plastic used in their construction. 
1. Type of Plastic Material
High-Impact ABS Plastic: Many plastic torpedo levels are made from high-impact ABS plastic, which is designed to be durable and resistant to cracking. ABS can generally handle moderate temperature fluctuations without becoming brittle or warping. However, in extremely high or low temperatures, even ABS can lose some of its structural integrity.
Polycarbonate Plastic: Polycarbonate is another common plastic used in more robust torpedo levels, offering higher resistance to both impact and temperature extremes compared to ABS. It’s less likely to crack or warp under harsh conditions, though it is more expensive.
2. Temperature Ranges
Heat Resistance: While many plastics can withstand moderate heat, prolonged exposure to very high temperatures can lead to softening, which might cause warping or deformation. Plastic torpedo levels are generally not designed for direct, prolonged exposure to temperatures above 120°F (49°C).
Cold Resistance: In extremely cold conditions, some plastics can become brittle and more prone to cracking. ABS, for example, can withstand cold to an extent but may become more susceptible to impacts in freezing temperatures. Polycarbonate can endure colder temperatures better without becoming as brittle.
3. Construction and Design Features
Reinforced Designs: Some plastic torpedo levels are reinforced with ribs or thicker walls, which helps them resist deformation and cracking under stress and temperature changes.Temperature Ratings: Certain manufacturers will specify a temperature range within which their plastic torpedo levels can operate effectively. Checking for this information can provide insight into how well a particular model is expected to withstand extreme conditions.
4. Proper Usage and Storage
Storage Practices: Storing plastic torpedo levels in a temperature-controlled environment can help prolong their lifespan and prevent warping or cracking. Direct sunlight, for instance, can cause temperature buildup and potentially lead to deformation over time.
Short-Term Exposure: Plastic torpedo levels can generally handle brief exposure to extreme temperatures without significant damage, but long-term exposure should be avoided to maintain their integrity.
While plastic torpedo levels are generally durable for everyday use, they may not offer the same extreme temperature resistance as those made from metal or aluminum. For tasks involving very high or low temperatures, metal torpedo levels might be preferable due to their increased durability under such conditions.
