Is the key buckle card made of ABS material? Or PVC material is better ? |

Today, a client asked me whether I should use ABS material to make a keychain card. Or PVC material is better? I believe there are many customers who do not know much about these two kinds of materials, so let me introduce them.
First of all, there is the introduction of ABS material. ABS is a kind of polymerization product synthesized from acrylonitrile (A), butadiene (B) and styrene (S). Its name is named after the first letter of the English name of the base material. And ABS is a kind of resin with high strength, good toughness and excellent comprehensive properties, so it is also known as ABS resin. ABS resin can be processed into plastics by injection molding, extrusion, vacuum, blow molding and rolling, as well as mechanical, adhesive, coating, vacuum steaming and other methods for secondary processing. Because of its excellent comprehensive performance and wide range of uses, it is mainly used as engineering materials and household appliances. Because of its good resistance to oil, acid, alkali, salt and chemical reagents, and electroplating, it has the advantages of good gloss, light specific gravity, low price and so on.
The second is the introduction of PVC material, PVC is a kind of polymer material in which a chlorine atom is used to replace a hydrogen atom in polyethylene. Therefore, it is called polyvinyl chloride (PVC). The density of rigid PVC is 1.38g / 1.43g / cm ~ 3. It has high mechanical strength and good chemical stability. The most important feature of PVC is flame retardant, so it is widely used in fire prevention applications. But PVC releases hydrochloric acid and other toxic gases during combustion.
Through the above understanding of the material characteristics of ABS and PVC, and then according to the use characteristics of the key card, I prefer the ABS material to do the key card, because ABS has high strength, good toughness, can be injection molding, extrusion, vacuum, blow molding and rolling, can make various styles of key card. In addition, ABS can be electroplated, so the key buckle card made by ABS has a more real and beautiful appearance. This is difficult for PVC materials to do. However, PVC material has the property of flame retardant, which is the most direct reason for its wide application. If you make a key lock card with flame retardancy, you should choose PVC material to do it. If you do not have too high requirements for flame retardancy, it is recommended that you choose ABS material to make key lock card.
