Product details
High Performance PP-C+H Sheet Material:
Engineering Solutions for Extreme Environments Choosing the right grade of polypropylene is the foundation of any successful industrial build.
At Foshan Anheda, we have the specialized Polypropylene Sheet material which is a compromise between mechanical rigidity and environmental resilience. Engineers around the world depend on our sheets for the reliability they need in applications from high-heat chemical processing to rugged outdoor infrastructure.

Primary Application Scenarios
1. A sound chemical infrastructure
Our high stiffness PP-C H Polypropylene sheet chemical grade is the choice for large scale structural projects. The homopolymer (PP-H) structure provides the needed stiffness to resist sagging or "bowing" under the weight of heavy acidic or alkaline solutions in tanks. It is able to maintain its structural integrity at temperatures up to 100°C and is a must-have for steel pickling and electroplating lines.
2. Tough Outdoor Gear
Polypropylene can become brittle if exposed to sunlight and cold for long periods of time. To counter this we have UV resistant Polypropylene Plastic Sheets +C H sheet outdoor versions available. These sheets are tough and flexible thanks to the impact-resistance of copolymer (PP-C) combined with UV stabilizers, even when exposed to changing temperatures and direct UV, so your outdoor chemical cabinets won’t crack or deteriorate over time.
3. Fabrication of Precision Components
To machine parts to high tolerances, you need a material that doesn't warp after the first cut. Our PP-C H plate is precision stress-relieved by a special annealing process to remove internal stresses from manufacture. This provides the “zero-drift” stability that is necessary for high-end industrial equipment when milling complex manifolds or pump impellers, so that the material remains perfectly flat.
One of the benefits of the natural translucent white finish that we often see clients overlook. In a recent project for a chemical supplier in Thailand, the customer switched from opaque grey to our natural white PP-C H sheet.
This simple innovation allowed their operators to see directly the sediment levels and chemical reactions through the tank walls. They used the high stiffness PP-C H sheet chemical grade together with the visual advantage to improve operational safety and reduce the need for expensive internal sensors that often corrode in acid environments.
Frequently Asked Questions (FAQs)
Q: When do I need to use PP-C over PP-H?
A: Use PP-H for high stiffness and high-heat applications. Use PP-C instead for applications requiring higher impact strength, especially if the equipment is to be used in colder climates or if the UV resistant PP-C H sheet must have outdoor properties.
Q: Is “stress-relieved” really that important in CNC machining?
A: That’s ok. If you don’t use a precision stress-relieved PP-C H plate, the material will have a curl to it as soon as you remove the top layer of skin, because of its internal “memory.” Our annealed plates lay flat saving you time and reducing scrap rates.
Q: Is the Natural White FDA approved?
A: Yes, our natural PP-C/H materials are non-toxic, halogen free and FDA compliant which makes them safe for both food processing and semiconductor wet-bench applications.
