There are two commen plastic materials for bristle block which is used on auto cutter. One is nylon ( Polyamide 6, PA6 ), and the other one is PP (Polypropylene ). Both of them are wildely used on plastic products. But due their different chemical character, you may choose the material for bristle based on different envirement .
|Material advantages||1.Excellent surface finish even when 2.reinforced|
5.Chemical resistance to hydrocarbons
|Material limitations||1.High water absorption|
2.Poor chemical resistance to strong acids
|1.Poor impact resistance at low temperature|
2.Difficult to paint or bond with adhesives
3.Molded surface is not smooth with glass 4.reinforcement
|Bristle advantage||1.Durable, long life |
2.Not easy be cut by blade
|1.Cheaper price than nylon bristle|
2.Size is stable even in wet weather
|Bristle disadvantage||1.Size will be bigger in wet enviroment||1.life is not as long as nylon bristle|
2.can easy be cut by blade due to it is not so flexible
|Apllication suggestion||1.work shop with air conditioner or dehumidifier |
|South Asia countries without air conditioner or dehumidifier|
Different auto cutters use different material
Based on above details, different fabric auto cutting machines use different material for their bristles. You may check below list for a reference.Some have both kinds of materials.And some only choose one .
|Shima Sakei bristle||yes||/|
You will see only Gerber have nylon bristle and PP bristle as their spare parts. Rest cutter companies only choose one material .As for Yilow, we will follow the material of original ones. But If clients asked new material, we can setup tooling for them and do OEM color. Please kindly note Nylon bristle and PP bristle can not share same tooling. If make both Nylon and PP in one tooling, the size will be different. That means, nylon bristle can only be made by tooling which designed for nylon .And meanwhile, PP bristle can only be made out by tooling which designed for PP.
