PP Sheet Classification
Based on the material formula, structure, and application, polypropylene sheet can be divided into the following common types:
?
1. Standard PP Sheet (Homopolymer PP)
Made from homopolymer polypropylene, it has high crystallinity and strong rigidity, but slightly lower toughness.
?
Suitable for general industrial applications such as protective panels, partitions, and linings.
?
2. Copolymer PP Sheet (Block/Random Copolymer PP)
Through copolymerization modification (such as the addition of ethylene monomer), impact toughness and low-temperature performance are improved.
?
Suitable for applications requiring impact resistance and low-temperature resistance, such as cold storage pallets and cryogenic containers.
?
3. Glass Fiber Reinforced PP Sheet
Glass fiber (GF10%, 20%, etc.) is added to improve rigidity, dimensional stability, and heat resistance.
?
Suitable for structural supports, mechanical parts, and high-temperature platforms.
?
4. Flame Retardant PP Sheet
Flame retardants are added to achieve flame retardancy ratings such as UL94 V-0/V-2.
?
Suitable for use in fire-resistant applications such as electrical equipment enclosures, rail transit, and public facilities.
?
5. Antistatic/Conductive PP Sheet
Adjustable surface resistance is achieved by adding antistatic agents or conductive materials such as carbon black.
?
Suitable for electronics factories, clean rooms, and anti-static workbenches.
?
6. Food-Grade/Medical-Grade PP Sheet
Complies with food contact safety standards such as FDA and LFGB, as well as relevant medical industry certifications.
?
Used for food processing, pharmaceutical packaging, and laboratory equipment.
How to Choose the Right Polypropylene Sheet?
?
Using Temperature
For room temperature, choose standard PP; for low temperature, choose copolymer PP or toughened PP; for high temperature, choose glass fiber reinforced PP.
?
Load Requirements
For high loads, choose thickened sheet or glass fiber reinforced sheet.
?
Chemical Media
Select oxidation and corrosion resistance based on the type of chemical contact.
?
Appearance Requirements
Requires color, printing, or transparency.
?
Hygiene Requirements
For food/medical applications, choose FDA/medical-certified grades.
?
Processing Methods
Select process-friendly options for bending, welding, engraving, etc.
