Many metals, such as cast iron, ceramics, and certain polymers are known to be brittle. They lack the ability to deform plastically and instead fracture easily under stress. Examples include glass, carbon fiber, and some types of plastics.
To prevent plastic from becoming brittle over time, you can store it away from sunlight and heat, avoid exposing it to harsh chemicals, and regularly clean and maintain it. Additionally, using plastic products within their recommended temperature range can help prevent brittleness.
Yes, alcohol can degrade or break down certain types of plastic materials. Alcohol can weaken the structure of plastics, causing them to become brittle or disintegrate over time.
no, it is very brittle
The old branches of the tree were brittle and snapped easily in the wind.
endothermic glad to see you're doing your homework (:

Plastics can be designed to be very brittle or very tough and flexible. Polymethyl methacrylate is quite brittle for example.
keeps them strong, and prevents them from becoming brittle
The polymers in the plastic insulation oxidize over time and deteriorate, becoming brittle. Teflon and other modern plastics used for insulation are far more resistant to this process and will last many decades without becoming brittle compared to earlier plastics used before, especially natural rubber (which could become brittle in only a couple of years).
to reduce hardness to prevent the material from becoming brittle
There are many types of plastic. Brittle plastic can be broken, and softer plastics can usually be cut with scissors or a saw or sharp knife.

PVC is kind of brittle to start with, though it becomes more brittle with age if exposed to sunlight, because UV rays break some of the bonds in the molecules. "Vinyl" (flexible PVC) is flexible because it has additional compounds called "plasticizers" added to it. Over time, these can leach out, again leading to a more rigid and brittle material.
Improving impact strength for brittle plastics can be achieved through various methods such as incorporating impact modifiers like elastomers, using toughening agents such as rubber particles or fibers, optimizing processing conditions to reduce internal stresses, and designing components with geometric features that distribute stress more evenly.
Brittle materials are those that break or fracture easily when subjected to stress without significant deformation. Common examples include glass, ceramics, and some types of plastics. If you provide a specific list of options, I can help identify which one is brittle.
