Polypropylene Sheet Durable, Chemically Resistant, and Versatile

Polypropylene (PP) sheet is a highly underrated thermoplastic known for its outstanding balance of chemical resistance, mechanical performance, and cost-efficiency. With minimal moisture absorption (just 0.03%) and a wide continuous operating temperature range from -160°C (copolymer) to +100°C, and excursions up to +130°C, polypropylene is well-suited for a variety of industrial, fabrication, and chemical handling applications.

Key Properties:

• Excellent Chemical Resistance: Highly resistant to a wide range of acids, bases, and solvents, making it ideal for chemical storage tanks, liners, and process equipment.
• Superior Mechanical Strength: Excellent stiffness, impact strength, and very high fatigue resistance, even under long-term load and stress.
• Thermoformable: Easily formed into complex shapes using heat, making it ideal for custom trays, covers, and housings.
• Food-Safe: Natural grades (low transparency) are approved for food contact, suitable for food industry applications such as cutting boards, trays, and process equipment.
• Corona Treatable: Can be surface-treated for printing, gluing, or labelling via corona discharge.
• Electrical Performance: Available in electrically conductive and static dissipative grades for ESD-sensitive environments.
• Limitations:
  Not naturally UV-resistant – requires UV stabilisers for prolonged outdoor exposure.

Not resistant to aromatic or chlorinated hydrocarbons, and must avoid contact with copper or manganese, which can degrade the polymer structure.

Standard Applications:

• Bearings & bushings
• Pump components
• Tank and chemical liners
• Industrial trays and covers
• Cutting surfaces and worktops
• Cleanroom and food processing surfaces

Available Grades:

• Homopolymer – Higher stiffness and strength, ideal for machined parts.
• Copolymer – Better impact resistance and low-temperature performance.

Modified Grades:

• Glass-filled for added stiffness
• Electrically conductive
• Static dissipative
• Fire-retardant (FR) formulations

Standard Colours:

• Natural (translucent white)
• Grey
• Custom colours available on request
