1. Product Overview

Our High Density Polyethylene (HDPE) Flat Plate is a versatile engineering plastic known for its high strength-to-density ratio. It is a rigid, durable material that offers excellent chemical resistance and low moisture absorption.

Whether you need a smooth flat plate for chemical tank construction or a textured HDPE board for playground equipment, our factory provides precision-manufactured sheets that meet strict international quality standards, including FDA and REACH compliance.

2. Key Features

High Impact Resistance: Extremely tough and flexible, even at low temperatures.

Chemical & Corrosion Proof: Highly resistant to most acids, alcohols, and bases, making it ideal for chemical storage.

FDA & USDA Approved: Naturally non-toxic and odorless; safe for direct food contact and medical applications.

Zero Water Absorption: Does not rot, swell, or harbor bacteria, ensuring a long service life in moist environments.

Easy to Fabricate: Can be easily welded using plastic welders and is excellent for CNC routing, sawing, and drilling.

Lightweight & Cost-Effective: A more economical alternative to metal or other high-cost engineering plastics without sacrificing durability.

6. FAQ Section

Q: What is the main difference between HDPE and Polypropylene (PP)?

A: HDPE has better impact resistance at low temperatures and is more flexible, while PP has a higher melting point and better stiffness for high-heat applications.

Q: Is your HDPE plate UV resistant for outdoor use?

A: Our standard black HDPE has excellent UV resistance. For colored plates used outdoors, we can add UV stabilizers to prevent fading and brittleness.

We are a manufacturer of high-quality high-density polyethylene (HDPE) sheets, specializing in custom production.
