Frequently Asked Questions (FAQs)
Q1: Does Sinopec Hunan Petrochemical BL1340H PA6 require pre-drying treatment before injection molding?
A: Given the hygroscopic nature of polyamide (PA6) materials, to prevent moisture from causing resin hydrolysis, generating bubbles, or reducing mechanical performance during high-temperature processing, strict drying treatment is recommended prior to injection molding (typically using a dehumidifying dryer at 80–90 ℃ for 4–6 hours to control moisture content below 0.2%).
Q2: What is the specific melt processing temperature range for this grade?
A: Based on the processing characteristics of conventional PA6 resin, barrel temperatures are generally recommended to be set between 230 ℃ and 270 ℃. Specific temperatures can be fine-tuned according to the injection molding machine model, mold structure, and part wall thickness, while mold temperatures are recommended to be maintained at 60–80 ℃ to ensure uniform crystallization and surface quality.
Q3: How can samples be requested and bulk supply capacity confirmed when evaluating material performance?
A: We support providing compliant laboratory test samples to industrial clients with actual application needs. Clients can submit specific application scenarios and testing requirements through official channels, and we will provide corresponding COAs and samples, while our professional supply chain team will confirm spot inventory and scheduling delivery plans based on order planning.
