PS Q & A
Q: Is PS recyclable?
A: Yes, but recycling rates vary by region. EPS is more challenging to recycle due to its lightweight nature.
Q: What's the difference between PS and PP?
A: PP (Polypropylene) has higher heat resistance and flexibility, while PS is more rigid and cost-effective.
Q: Can PS be used for food contact?
A: Yes, if it's FDA-approved food-grade PS.
Q: How do I store PS materials?
A: Keep in a dry, cool place away from direct sunlight to prevent degradation.
Q: What's the typical lead time for PS orders from China?
A: Usually 2-4 weeks, depending on order size and customization requirements.
