Because the Teardrop Anti-Theft Pull Box is an electric retractable device, it is mainly used for display and anti-theft in supermarkets and stores. Therefore, it needs to have good stickiness and lightness so that customers can hold it in their hands to view and prevent theft.After intensive screening, Bestmetal discovered the ABS material.
ABS plastic is a kind of "tough, hard and rigid" material with easy-to-obtain raw materials, good comprehensive performance, low price and wide range of uses. ABS plastic has been widely used in machinery, electrical, textile, automobile, aircraft, ship and other manufacturing industries and chemicals.
ABS is a terpolymer of acrylonitrile, butadiene and styrene. A stands for acrylonitrile, B stands for butadiene, and S stands for styrene. After actual use, it was found that: ABS plastic pipes are not resistant to sulfuric acid corrosion, and smashed and cracked when encountered with sulfuric acid.
Because of its three compositions, it has good performance; Acrylonitrile gives ABS resin chemical stability, oil resistance, certain stiffness and hardness; Butadiene improves its toughness, impact and cold resistance; Styrene gives it good dielectric properties and exhibits good processability.
Most ABS is non-toxic and impervious to water, but slightly permeable to water vapor, and has a low water absorption rate. The water absorption rate of room temperature immersion does not exceed 1% for one year without any change in physical properties. The surface of ABS resin products can be polished, and highly glossy products can be obtained. It is 3-5 times stronger than general plastics.
Because of these good characteristics, Best finally chose ABS as the main material of the Teardrop Anti-Theft Pull Box.
