Plexiglass, also known as acrylic, is one of the most transparent materials available today. With a light transmittance of up to 92%, it outperforms regular glass, which typically allows only about 80% of light through. This high transparency makes plexiglass ideal for applications where clarity is essential, such as in aquariums, signage, and even in medical equipment. In fact, the sun lamp, often called the "artificial sun," uses quartz because it's completely transparent to ultraviolet light. However, plexiglass can transmit up to 73% of UV light, compared to just 0.6% from ordinary glass, making it a better choice for UV-sensitive applications. Another major advantage of plexiglass is its high mechanical strength. With a molecular weight of around 2 million, it's a long-chain polymer that provides exceptional toughness. Its tensile and impact resistance are significantly higher than that of regular glass—up to 18 times stronger. When heated and stretched, the molecular structure becomes more ordered, increasing its durability even further. For instance, if you drive a nail through plexiglass, it won't crack or shatter. Even when shot at, it doesn't break into dangerous shards. This property makes it suitable for use as bulletproof glass or as protective canopies on military aircraft. In addition to its strength, plexiglass is remarkably lightweight. It has a density of 1.18 g/cm³, meaning it weighs about half as much as regular glass and only 43% of aluminum, which is already considered a light metal. This makes it an excellent material for applications where weight is a concern, such as in automotive parts, aerospace components, and large-scale structures. Plexiglass is also very easy to process. It can be cut with lathes, drilled with drills, or even dissolved using solvents like acetone or chloroform. It can be molded into complex shapes using techniques such as blow molding, injection molding, and extrusion. These properties allow it to be used in a wide range of products, from large aircraft cockpits to small dental trays and everyday items like food containers and display cases.
The welding back caps and the valve stems is also the important parts in the tig welding torches .They are all used in the torch bodies .The back caps have two :the long back cap and the short cap .The valve is used in the valve torch body .It also have a protection .The back caps have several series :the 41V,the 57Y ,the 56Y .The valve stem just have two ,the VS-1,VS-2 .The customer can choice based on their need .
