We can find Plastic Buttons on a variety of clothing such as shirts and skirts. Of course, Snap fastener tape, Spring snap button, Printed Sewing Button, and Jeans Button are also commonly used button types, but today we mainly discuss Plastic Buttons.

The material of plastic buttons is of course plastic. There are also many types of plastic materials, and now people mainly use: ABS, PP, polycarbonate, AS, acrylic, etc. The main material of the button is ABS resin.

ABS resin is a copolymer of three monomers: Acrylonitrile, Butadiene, and Styrene. Among them, acrylonitrile accounts for 15% -35%, butadiene accounts for 5% -30%, and styrene accounts for 40% -60%. The most common ratio is A: B: S = 20: 30: 50. The melting point of the resin is 175 ° C. The combination of these three components gives the ABS resin good performance. Acrylonitrile makes it have chemical stability, oil resistance, certain rigidity and hardness; butadiene makes it tough, impact and cold resistance improved; styrene makes it have good dielectric properties and gloss, and shows good Processing characteristics.

Most ABS resins are non-toxic and have low water absorption. Experiments show that the water absorption of the sample at room temperature for one year does not exceed 1%, and its physical properties have not changed.The surface of ABS resin products can be polished to obtain high gloss products.

ABS has excellent physical and mechanical properties, excellent low temperature impact resistance, and has dimensional stability, abrasion resistance, chemical resistance, and dyeing properties. It is easy to be formed and machined. ABS resin is resistant to water, inorganic salts, alkalis and acids, and is insoluble in most alcohol and hydrocarbon solvents.

Sometimes, different fabrics and styles of clothing need buttons with different materials. If you have any questions about Apparel Button such as Alloy Jeans Button, Copper Jeans Button, Polyester Shirt Button, please contact us.
