One of the commonly used materials for making brushes is plastic, such as plastic brushed silk and plastic brushes, which can be processed into plastic silk brushes, plastic silk paint brushes and plastic handle paint brushes. There is also the use of plastic injection molding process to make large-scale roller roller core, etc., can be said that the plastic and brush industry is very close. The following brief introduction to the basic knowledge of several commonly used plastics.

PA, nylon plastic brush, its characteristics of tough, strong, wear-resistant, commonly used in the production of combs, toothbrushes, hooks, fan, net bag rope, fruit bags and so on. Non-toxic, but not long-term and acid-base contact. Brush industry is often used to do brush body, brush wire also used a lot.

PE, polyethylene plastic brush, chemical stability, usually making food bags and a variety of containers, acid, alkali and salt solution erosion, but not with a strong alkaline detergent wipe or soak.

PP, polypropylene plastic brush, non-toxic, tasteless, can be soaked in boiling water at 100 ℃ without deformation, no damage, common acid, alkali organic solvents almost no effect on it. Used for utensils. Brush industry is often used as a brush wire.

PVC, PVC plastic brush, bright color, corrosion resistance, durable, due to the increase in the manufacturing process of plasticizers, anti-aging agents and some other toxic auxiliary materials, so its products are generally not stored foods and medicines. Brush industry is often used to brush body or brush base.



PS, polystyrene plastic brush, easy to color, good transparency, and more for the production of shade, toothbrush handle, toys, electrical components. It is acid and alkali corrosion, but soluble in chloroform, vinylidene chloride, banana water and other organic solvents.



ABS, a plastic brush polymerized from acrylonitrile, butadiene and styrene. Its striking, heat-resistant and sturdy exterior can be plated with chrome, nickel and other metal films. It can be used to make keys, buttons, Umbrella handle and so on.
