Thermoset polymers, found in car parts and electrical appliances, have to be durable and heat-resistant, but typically cannot be easily recycled or broken down after use.

Thermoplastic elastomers (TPE) are a rubber-like material that combines the properties of rubber with the benefits of thermoplastics. The result is a flexible and recyclable material. Co-extrusion means that the TPE adheres to engineering plastics through melting when the surfaces are in contact with each other.

Bakelite is a cross linked polymer which after heating can’t be recovered in its original structure. Hence it is a thermosetting polymer. Rest all are thermoplastic polymer.

The primary difference between the two is that Thermoset is a material that strengthens when heated, but cannot be remolded or heated after the initial forming, while thermoplastics can be reheated, remolded, and cooled as necessary without causing any chemical changes.

The disadvantages of Polyacrylonitrile-butadiene-styrene (ABS) include:

• Poor solvent and fatigue resistance.
• Poor UV resistance unless protected.
• Maximum continuous use temperature approx. 70 °C ( 160 °F ).
• Poor bearing properties (high friction and wear).
• High smoke evolution.

Odor and emissions. ABS emits a strong odor when printed, the odor commonly known as burnt plastic. Not only does this smell makes it very uncomfortable to stay in the same room as the printer when it is working, but there are also studies that prove that the fumes are toxic.

PETG is more durable than ABS, but ABS is harder, and more rigid. PETG has a lower glass transition temperature, at 80C compared with ABS’s 105C. ABS is approximately 20% less dense than PETG. PETG won’t warp like ABS might (if printed incorrectly) and is generally odourless.

Yes, you are absolutely going to die if you print ABS.

Studies of the materials used for 3D printing, such as ABS, PLA, and nylon can be a source of dangerous VOCs such as styrene, butanol, cyclohexanone, ethylbenzene, and others. In particular, heating ABS at a temperature typical for 3D printing results in high VOC emission.

The results showed that the level of harmful particles and fumes depended mostly on the filament material, not the make of printer. ABS emitted styrene – a chemical that is both toxic and carcinogenic. The PLA filament emitted a benign chemical named lactide.

This thermoplastic material has excellent chemical, stress and creep resistance. ABS is considered a food grade thermoplastic, and can be safe for use in food processing. ABS plastic remains hard, rigid and tough even at low temperatures. It is available in fire-retardant, heat-resistant and platable grades.

Potential effects of ABS on the body Researchers have concluded that many of the constituents of ABS in their isolate form are carcinogenic. This means that if these substances are ingested, it increases the chance of cancer formation.

ABS is a very stable resin that does not leach chemicals into food or water. All IPS abs cements are safe for drinking water, however I dont believe #16 falls into this category.

ABS is relatively safe to handle as it cools down and hardens, making it one of the easiest plastics to handle, machine, paint, sand, glue, or otherwise manipulate.

A company that’s making parts for machines will be better off when choosing ABS, because of its lifespan, its strength and its higher melting point….ABS.

The muscles of your abs stabilize your torso to maintain good posture. Strong abs and back muscles are crucial for preventing lower back pain and injury. If your torso isn’t strong or is imbalanced, you’ll quickly become one of the millions of people with chronic lower back pain.

ABS (Acrylonitrile Butadiene Styrene) is a low-cost engineering plastic that bridges the gap between standard plastics and high-performance engineering thermoplastics. Natural (beige) ABS is FDA-compliant for use in food-processing applications.

While it’s true that the individual ingredients, such as styrene, may be toxic on their own in liquid/vapor forms, ABS plastic resin seems to be stable and non-leaching. It’s tossed into the “catch-all” category #7 of plastic recycling codes.

ABS (Acrylonitrile Butadiene Styrene), which Lego is made from, is a safe plastic. BabyBjorn also use ABS – it’s BPA free. Plastics made from corn starch resin are lumped into the #7 category, and these are BPA free too.
