Viii. <\/span>FAQ (Frequently Asked Questions by Purchasers)<\/span><\/h2>\n

 <\/p>\n

Q1: Will the size of PA6 be affected after absorbing water?<\/span><\/strong><\/p>\n

A1: Yes. After absorbing moisture, the size will expand. It is recommended to use a glass fiber reinforced type or undergo drying treatment.<\/span><\/p>\n

Q2: Can POM be blended with PA6 for use?<\/span><\/strong><\/p>\n

A2: Not recommended. The two have poor compatibility and may cause delamination and cracking problems.<\/span><\/p>\n

Q3: Which material is more suitable for sliding parts?<\/span><\/strong><\/p>\n

A3: POM has natural self-lubricating properties and outperforms PA6 under dry friction conditions.<\/span><\/p>\n

Q4: Which is more heat-resistant, PA6 or POM?<\/span><\/strong><\/p>\n

A4: PA6 has a slight edge. The long-term service temperature is approximately 120\u2103, and POM is about 100\u2103.<\/span><\/p>\n

Q5: Which one is easier to injection mold?<\/span><\/strong><\/p>\n

A5: POM has higher fluidity, but attention should be paid to temperature control to avoid thermal degradation.<\/span><\/p>\n

 <\/p>\n
