• Excellent impact strength and wear resistance

• Low water absorption, ensuring stability in humid environments

• Smooth, hygienic surface that is easy to clean

• Lightweight yet durable, making fabrication and installation efficient

Specifications and Models

The anti-corrosion and acid-alkali resistant HDPE sheets are available in multiple sizes, thicknesses, and colors to meet diverse industrial requirements.

Note: Custom sizes, colors, and surface finishes are available upon request.

Installation Steps

Correct installation ensures that the HDPE engineering plastic sheet maintains its performance and structural integrity in corrosive environments.

Step 1: Preparation

• Clean the installation surface to remove dust, oil, or debris.

• Ensure the surface is level and free from sharp edges that may damage the sheet.

• Verify the sheet dimensions according to the project requirements.

Step 2: Cutting and Fabrication

• Use standard plastic cutting tools such as circular saws or routers.

• For welding and joining, use hot gas welding or extrusion welding techniques.

• Maintain proper ventilation during cutting and welding to ensure safety.

Step 3: Positioning

• Place the sheets in the required position, leaving minimal gaps.

• For applications requiring waterproofing or chemical containment, ensure tight alignment of edges.

Step 4: Fastening

• Fix the sheets using corrosion-resistant bolts, screws, or welding.

• Use expansion gaps when installing in environments with large temperature variations.

Step 5: Final Inspection

• Check for surface scratches or cracks caused during installation.

• Test joints and welded areas for leak resistance in containment applications.

• Ensure the installation meets safety and quality standards.

Fault Causes and Solutions

Even though HDPE sheets are durable, improper installation or environmental factors may cause issues. Below are common problems and troubleshooting solutions:
