**IV. Product Classification**
Based on different manufacturing processes and raw materials, HDPE sheets are categorized as follows:
1. **High-Density Polyethylene Sheet:** Density 0.96 - 0.98 g/cm³
**V. Chemical Resistance**
* Suitable for general acidic, alkaline, saline solutions, and organic solvents (especially active solvents).
However, it will be corroded by chemicals such as chlorinated solvents, aliphatic hydrocarbons,
and aromatic hydrocarbons. Not suitable for concentrated nitric acid, chromic acid, etc.
**VI. Food Contact Performance**
* **Food-grade material**, suitable for direct contact with food and pharmaceuticals.
**VII. Product Characteristics**
1. Excellent toughness and dimensional stability.
2. Reliable insulation performance, good heat resistance.
3. Resistant to acids, alkalis, and chemical corrosion.
4. Easy to process, excellent welding performance.
5. Non-toxic, environmentally friendly, durable.
**VIII. Processing Performance**
