 （一）POM材 material brief introduction

advantages:

high rigidity, high strength, mechanical properties maintain stability property;

resistant creep, resistant fatigue, high elastic property modulus;

resistant scratch abrasion consumption, lubricated features;

resistant machine product and various type;

surface 美观, gloss degree high, easy molding;

suitable for parts 模塑, metal parts upper injection molding and 切削, and other.

disadvantages:

heat stabilized property 差, high temperature lower material easy separation understanding;

high crystallization, molding shrinkage large;

缺口 impact low;

不 resistant strong/high acid strong/high alkali.

（二）POM in automotive field/area application

automotive industrial is POM most large in market. POM质 light, low, processing molding 简便, production cost low 廉, can substitute/replace separation metal in automotive upper use, meet/satisfy automotive light amount development direction.

modified POM friction coefficient low, wear resistant consumption, rigid property strong/high, non combined manufacturing automotive 传动部 parts and function parts.

function parts POM modified material

4, modified POM in 车门部 parts upper application

5, modified POM in 油箱部 parts upper application

6, modified POM in safety belt/tape and upper application

M9010-ST series property can Comparison Table

(三）POM材 material processing process

high crystallization property, melt temperature degree narrow, material temperature low melt temperature degree 即发生 crystallization;

flow property in and other, melt degree 受剪切 speed rate effect/influence large temperature degree effect/influence;

water absorption low, molding front need micro drying 处理;

heat stabilized 差, easy separation understanding, separation understanding temperature degree is 240 ℃, processing ultra- melt time long;

molding shrinkage large is 1.5%~3%, shrinkage solution, in made process conditions and mold design 时应引起 attention/notes.
