05 | FAQ<\/span><\/h2>\n

 <\/p>\n

Q1: What's the difference between PPSU Unfilled Extruded and PPSU LSG?<\/span>
\nA1: Unfilled Extruded has a higher flame retardant grade (V-0), stronger electrical insulation strength, and is suitable for high-end fields.<\/span> LSG, on the other hand, emphasizes mechanical strength and impact toughness, offering better value for money.<\/span><\/span><\/p>\n

Q2: Why does LSG PPSU have fewer parameters?<\/span>
\nA2: LSG PPSU is a special application model, mainly used in scenarios with friction performance requirements, so the complete set of mechanical and thermal data is not provided.<\/span><\/p>\n

Q3: If I want to make a medical device shell, which model should I choose?<\/span>
\nA3: PPSU Unfilled Extruded (high flame retardancy and high strength) or PPSU LSG (balancing mechanical performance and cost-effectiveness) is recommended.<\/span><\/p>\n

Q4: Compared with PEI and PEEK, what are the advantages of PPSU?<\/span>
\nA4: PPSU has more advantages in chemical resistance, impact performance and cost control, and is an upgraded choice for PEI and a cost-effective alternative to PEEK.<\/span><\/p>\n

Q5: Are these models easy to procure in the supply chain?<\/span>
\nA5: As a professional trader, our company can supply the QUADRANT Cross-Jun PPSU series for a long time and provide customers with flexible purchasing and customization services.<\/span><\/p>\n
