Most metal detectors are capable of detecting titanium. but some low-cost ones may not be sensitive enough. This depends on the quality and type of metal detector. Airports and high-security areas. for example. usually have high-quality metal detectors capable of detecting titanium.

Polyethylene (PE) is a thermoplastic polymer composed of ethylene monomers (CH2=CH2) linked together. The chemical formula for the repeating unit can be represented as (C2H4)n, where 'n' denotes the number of ethylene units in the chain. The properties of polyethylene, such as density, stiffness, and melting point, vary significantly with the chain length and branch structure, leading to different grades like High-Density Polyethylene (HDPE) and Low-Density Polyethylene (LDPE). HDPE has a linear structure with minimal branching, resulting in stronger intermolecular forces and higher tensile strength. On the other hand, LDPE features considerable chain branching, which prevents the polymer chains from packing closely, making it less dense and more flexible. Polyethylene is widely used in packaging, containers, and plastic parts due to its durability, resistance to chemicals, and ease of processing.

Low density polyethylene (LDPE) is a thermoplastic polymer made from the monomer ethylene through a process known as free radical polymerization at high pressure. It is characterized by its soft, flexible nature, making it ideal for products like plastic bags, containers, and tubing. LDPE contains long-chain polymer units with significant branching, which reduces the density and makes the material less rigid and more pliable compared to its counterpart, high-density polyethylene (HDPE). Its properties make it a popular choice for applications requiring flexibility and durability.
