What is the heat resistance temperature of ABS?

[DelReagan]

ABS plastic has a heat deflection temperature of 93118°C, which can be increased by about 10°C after annealing treatment. ABS can still exhibit certain toughness at -40°C and can be used within a temperature range of -40100°C. The following is relevant information about ABS: ABS plastic appears as opaque ivory-colored pellets, and its products can be dyed in various colors with high gloss. ABS has a relative density of about 1.05 and low water absorption. ABS bonds well with other materials and is easy to surface print, coat, and plate. The oxygen index of ABS is 18~20, making it a flammable polymer with a yellow flame, black smoke, and a distinctive cinnamon odor. ABS has excellent mechanical properties, with outstanding impact strength, allowing it to be used at very low temperatures. ABS also has good wear resistance, dimensional stability, and oil resistance, making it suitable for bearings under moderate loads and speeds.

I've been repairing auto parts for years, and ABS plastic is quite a common material, found in components like dashboards, door panels, or bumpers. Its heat resistance typically ranges between 80 to 100 degrees Celsius, depending on the formulation and manufacturing standards. If your car is parked under direct sunlight, the interior temperature can rise above 60 degrees, potentially causing ABS parts to soften and deform, affecting functionality. I always advise fellow car owners to manage temperature carefully—for instance, parking in the shade or using sunshades during summer. In practical tests, ABS may start softening beyond 90 degrees, accelerating aging. During modifications or repairs, I prioritize heat-resistant variants to ensure long-term safety and reliability. Also, don’t forget that high temperatures can cause ABS to emit unpleasant odors, impacting health, so regular checks for signs of aging are crucial.

Back when I used to DIY car modifications with ABS sheets, there was one time I was welding nearby components on a hot day, and the ABS actually started to warp. After researching, I learned that ABS typically has a heat resistance range of around 85 to 105 degrees Celsius. Beyond this range, the plastic can easily soften or melt. Now, before starting any project, I always check if the ambient temperature is too high, especially near the engine or in direct sunlight areas. While ABS is affordable and easy to work with, its thermal stability isn’t top-tier, so extra caution is needed around heat sources. Since that lesson, I’ve added ventilation fans in my garage and avoid working during hot afternoons. Remember, prolonged exposure of ABS to environments above 90 degrees can lead to premature failure and increased maintenance costs. Choosing the right materials can save a lot of trouble.

When driving long distances frequently, temperature changes can be significant, and ABS material becomes very dangerous under extreme heat. Its heat resistance is approximately 80 to 100 degrees Celsius, beyond which it deforms. I have experienced issues with interior warping under the scorching sun in the south. Parking strategy is crucial: choose shaded areas or use reflective mats.
