Shanghai Daoqin Plastics Co., Ltd.

improves nylon （PA, polyamide (PA) ）材 material wear resistance can through multiple methods achieve, 包括材 material modified, add filler, use reinforcement fiber and surface treatment and other. below/following is Common methods:  

1. add filler

glass fiber （GF）: glass fiber reinforcement nylon not only can improve/increase material strong/high degree and rigid property, also can significantly improves wear resistance.

carbon fiber （CF）: carbon fiber not only provide high strength, also tool has relatively low friction coefficient, has improve/increase wear resistance.

二硫化钼（MoS2）: as is solid lubricant add to nylon in, can significantly reduce friction coefficient, improve/increase wear resistance.

PTFE （PTFE）: PTFE pellets as is lubricant add to nylon in, can has drop low friction and abrasion loss.

2. add toughening agent and lubricant

toughening agent: 如橡胶 type toughening agent （SEBS, EPDM and other ） can improve/increase nylon tough property, from 而间接 improve/increase its wear resistance.

internal lubricant: add internal lubricant silicon or wax, has decrease/reduce scratch and abrasion loss.

3. chemical modified

copolymer modified: through and other mono copolymer （如 nylon 6 and nylon 66 copolymer ）, can adjustment material separation structure, improvement its wear resistance can.

grafting modified: through grafting mono or polymer, can reinforcement nylon surface hardness and wear resistance.

4. hot and crystallization degree control

hot 处理: through hot 处理, can improve/increase nylon crystallization degree, from improve/increase its wear resistance.

退火: process can understanding internal stress, improve/increase material uniform property and wear resistance.

5. surface treatment and coating

surface hard 化: through and other 离子体处理, 离子注入 and other methods, can hard nylon surface, significantly improve/increase its wear resistance.

coating: in nylon surface coating wear resistant coating （如PVD coating, carbon coating and other ）, can large improves surface wear resistance.

6. blending modified

blending other high property can polymer: and polyimide (PI) （PI） blending, can improves nylon wear resistance can and high temperature resistance property can.

nano material: add nano pellets （如 nano oxidation silicon, nano oxidation aluminum and other ）, can significantly improve/increase nylon wear resistance.
