A brush's service life is significantly impacted by how wear-resistant and resistant to deformation it is. We are all aware that nylon, PBT, and PP filament are the three most popular types of plastic brush filament. So, PP filament or nylon filament, which is more easily deformed?
Which one is easier to deformation, PP filament or nylon filament? In general, nylon filament is generally superior to PP filament. PP filament has excellent mechanical properties; its tensile strength can only reach 30 MPa or slightly higher. Meanwhile, PP filament has a small molecular weight, low density, high hardness, acid and alkali resistance, negligible water absorption, etc. The resilience and abrasion resistance, however, are not particularly good. It is typically used for medium and big outdoor cleaning brushes, domestic hygiene cleaning brooms, etc. because it is less expensive than nylon filament. Nylon filament has good toughness, strong abrasion resistance, oil resistance, shock resistance, good tensile and bending strength, negligible water absorption, good dimensional stability, etc. The melting and softening points are high, and the heat deformation stability can reach 80-100℃, so it is used to process various wear-resistant and high-strength parts.
