Frequently Asked Questions About HDPE & UHMWPE
What is the difference between HDPE and UHMWPE?
HDPE (high-density polyethylene) has a molecular weight of around 200,000–500,000 g/mol, while UHMWPE (ultra-high molecular weight polyethylene) has a molecular weight exceeding 3 million g/mol. UHMWPE offers superior abrasion resistance, impact strength, and self-lubrication, making it ideal for heavy-wear applications. HDPE is more cost-effective and easier to machine, suitable for general-purpose uses.
Can I buy HDPE rods or sheets directly from a China factory?
Yes, Kaxite Sealing is a direct China HDPE manufacturer, offering factory-direct pricing with no minimum order quantity for standard sizes. Submit your inquiry and we will provide a competitive quote within 24 hours.
What are the food-grade certifications for HDPE?
Our HDPE products are available with FDA 21 CFR 177.1520 and EU 10/2011 compliance for food contact applications. Please specify your requirement when requesting a quote.
Can you provide custom colors or additives for HDPE/UHMWPE?
Absolutely. We can add UV stabilizers, antistatic agents, or custom pigments to meet your application needs. We also offer machined parts – contact our China technical team for consultation.
What is the typical lead time for HDPE orders from China?
Standard sizes are usually in stock and ship within 3–5 working days. Custom orders typically require 7–15 working days, depending on quantity and specifications. We offer express shipping and sea freight options.
