This zircon is cracked and undissociated. It usually exhibits zygomatic fractures or uneven fractures.

Ultra High Molecular Weight Polyethylene (UHMWPE) is a subset of thermoplastic polyethylene with extremely long chains, resulting in a very tough material. Notably, UHMWPE boasts a density of 0.93 to 0.94 g/cm³, which is slightly lower than that of water. This characteristic density, along with its high impact strength, abrasion resistance, and low friction coefficient, makes UHMWPE ideal for a wide range of applications, from medical devices and body armor to industrial machinery components. The material's unique properties stem from its high molecular weight, which ranges from 3.5 to 7.5 million atomic mass units, providing a combination of durability and lightweight characteristics that are unmatched by most other polymers.

Medical polypropylene is a thermoplastic polymer widely utilized in the healthcare industry due to its excellent chemical resistance, sterilizability, and flexibility. Its primary uses include manufacturing surgical instruments, syringes, and medical containers. Due to polypropylene's ability to withstand high temperatures, it is suitable for autoclaving, ensuring sterilization of medical tools without degrading its properties. Furthermore, its flexibility and lightweight nature make it an ideal material for creating comfortable and durable prosthetic limbs and devices. The material is also used in packaging for medical devices, ensuring safety and maintaining the sterility of products during transport and storage. Another significant application is in suture manufacturing, where its non-absorbable nature is essential for wound closure procedures. The contribution of polypropylene to medical applications showcases its versatility and importance in developing safe, reliable, and practical medical products.
