PP sheet
PP sheet
A PP sheet (Polypropylene) is an incredibly lightweight, versatile, and economical commodity thermoplastic sheet known for its excellent chemical resistance to acids and alkalis. Unlike the precision focus of POM, PP is highly favored for applications requiring durability, good fatigue resistance (like in “living hinges”), and low moisture absorption.
Application: Common uses include chemical storage tanks, various food and non-food packaging, automotive parts, and construction materials like wall cladding and vapor barriers.
Color: Clear, Grey, White
Properties:
- excellent chemical resistance to acids, alkalis, and solvents
- Low density (very lightweight)
- High tensile strength and rigidity (stiffness)
- Excellent fatigue resistance (ideal for “living hinges”)
- Very low moisture absorption
- Good electrical insulation properties
- Up to 120 Celcius
PP rod
A Polypropylene (PP) rod is a solid, cylindrical piece of extruded thermoplastic. It is known for being a lightweight, economical, and highly versatile plastic with an exceptional balance of physical, chemical, and thermal properties. It is a common “workhorse” material used across many industries, similar in family to HDPE but generally offering better rigidity and heat resistance.
Key Properties
• Excellent Chemical Resistance
• Low Moisture Absorption
• Lightweight
• Good Mechanical Strength
• High Fatigue Resistance
• Good Thermal Resistance
• Weldability
• Food Safety
Common Applications
PP rod is machined, fabricated, and welded into a variety of components, including:
• Chemical Industry: Chemical storage tanks, tank linings, pipes, valves, and pump components.
• Food Processing: Cutting boards, food-safe machinery parts, conveyor components, and mixing paddles.
• Water Treatment: Filter housings, pump bodies, and fittings.
• Laboratory Equipment: Fume hoods, chemical-resistant work surfaces, and containment systems.
• General Manufacturing: Spacers, insulators, flanges, and rollers.
