Polypropylene (PP) sheets are lightweight, durable thermoplastic materials widely recognized for their versatility and sustainability. With a density of 0.9–0.91 g/cm³, PP sheets offer exceptional strength-to-weight ratios, making them ideal for applications requiring portability without compromising structural integrity. These sheets exhibit outstanding chemical resistance, tolerating exposure to acids, alkalis, and salts, which ensures reliability in industrial and construction environments. Their thermal stability allows usage in temperatures ranging from subzero conditions to 100°C, suitable for outdoor applications and heat-resistant packaging.
A key advantage of PP sheets is their eco-friendliness. Fully recyclable and compliant with food-grade safety standards (e.g., ENF certification), they align with global sustainability trends, particularly in packaging and healthcare sectors. Customizable properties further enhance their appeal: flame-retardant or anti-static modifications cater to specialized industrial needs, while corona-treated surfaces enable high-quality printing for branding and signage.

1. Lightweight & High Strength-to-Weight Ratio
PP sheets have an exceptionally low density of 0.91–0.93 g/cm³, making them one of the lightest thermoplastic materials while maintaining structural rigidity and impact resistance. Their hollow-structured variants further enhance shock absorption for industrial applications.
2. Excellent Electrical Insulation Properties
As a non-polar, semi-crystalline polymer, PP exhibits high intrinsic breakdown strength (up to 700 V/μm for BOPP films) and ultra-low dielectric loss (tan δ < 3×10⁻⁴), ideal for capacitors, electrical insulation, and high-frequency applications.
3. Superior Thermal Stability
PP sheets withstand temperatures ranging from subzero conditions to 100°C, with heat-resistant grades maintaining dimensional stability even at 105°C continuous operation (common in capacitors and automotive components).
4. Chemical & Moisture Resistance
Highly resistant to acids, alkalis, salts, and moisture, PP sheets show <0.01% water absorption over 24 hours, ensuring reliability in corrosive environments and humid conditions.
5. Customizable Surface & Mechanical Properties
Surface Roughness Control: Adjustable roughness (smooth "glossy" films for metalization or textured "matt" films for oil impregnation) to meet specific electrical or adhesion requirements.
Flame Retardant/Anti-Static Modifications**: Enhanced safety for industrial and electronic applications.
High Crystallinity & Isotacticity: Improves heat resistance and reduces thermal shrinkage (e.g., <1% transverse shrinkage at 120°C).
6. Eco-Friendly & Processable
PP sheets are 100% recyclable and comply with food-grade standards. Their melt flow rate (MFR ~3.0 g/10 min) and broad molecular weight distribution enable efficient processing into ultra-thin films (as low as 1.9 μm) or thick panels while minimizing defects like "stretch voids".
PP rigid sheets, also known as polypropylene rigid sheets, are widely utilized across industries due to their durability, lightweight nature, and customizable properties. Below are key application scenarios based on their characteristics:
1. Packaging Solutions
Transportation Boxes: Used for shockproof containers, mailboxes, and gift boxes, leveraging their impact resistance and ability to be easily cut or bent into custom designs.
Food Packaging: Ideal for moisture-resistant food containers and pharmaceutical packaging due to their waterproof, non-toxic, and recyclable nature.
Electronics Protection: Employed in reusable turnover boxes to safeguard delicate electronics during shipping.
2. Advertising & Signage
Display Boards: Printed with vibrant graphics for yard signs, road signs, exhibition boards, and retail point-of-sale displays, enhanced by corona-treated surfaces for improved ink adhesion.
Temporary Structures: Lightweight yet rigid sheets are used for trade show booths and warning boards.
3. Industrial & Construction Use
Protective Panels: Serve as wall cladding, padding boards, or baseboards in factories and warehouses, offering resistance to corrosion and mechanical stress.
Building Materials: Applied as partitions, ceiling panels, and air conditioning ducts due to their thermal insulation and soundproofing properties.
Drainage Systems: Corrosion-resistant sheets are used in plumbing and drainage applications, outperforming traditional materials in humid environments.
4. Decorative & Creative Projects
Interior Design: Utilized for partitions, false ceilings, and wall cladding in both indoor and outdoor spaces, available in multiple colors for aesthetic flexibility.
Art & Stationery: Favored for art installations, custom gift boxes, and decorative patterns, benefiting from their smooth surface and printability.
5. Specialized Industrial Modifications
Flame-Retardant Applications: Modified sheets are used in environments requiring fire safety, such as electrical component housings.
Anti-Static Solutions: Employed in electronics manufacturing to prevent static damage.
