Description

Polypropylene copolymer (PP-C) sheet is an extruded plastic commonly used for fabricated tanks, liners, and equipment in corrosive or wet environments. Compared with polypropylene homopolymer, PP-C is less rigid but tougher, with better impact strength at low temperatures and good resistance to stress cracking.

Buyers select it for chemical and corrosion resistance, low moisture absorption, light weight, and easy fabrication. It welds and thermoforms readily, and it stays flat and dimensionally stable during fabrication and machining, which helps production yield and finished part quality. The surface is scratch and stain resistant and easy to clean.

Advantages

Chemical resistance: resists many acids, alkalis, and salts in corrosive process environments; confirm compatibility for the specific chemical and conditions
Impact toughness: high impact strength and stress crack resistance, including at low temperatures
Low moisture absorption: practical in wet or humid settings
Lightweight: low density reduces the weight of fabricated assemblies
Fabrication options: can be machined, welded, and thermoformed
Service temperature: manufacturer data lists a maximum continuous service temperature of 180°F
Electrical properties: good dielectric behavior for nonconductive parts

Applications

Chemical tanks and equipment
Galvanizing tanks, plating lines, and related process equipment
Ducting and scrubbers
Wastewater management components
Fire truck tanks and equipment
Orthotic and prosthetic devices
Die pads and fabricated industrial parts
Food processing components

Buying Considerations

These sheets are not UV stabilized and are intended for indoor or sun-protected use. Chemical concentration, operating temperature, load, cleaning methods, and contact time all affect suitability. Confirm the material against the actual service conditions, including any food-contact or other regulatory requirements, before fabrication or installation.

Fabrication and Handling Notes

PP-C is commonly welded in tank and equipment fabrication, usually with matching polypropylene copolymer weld rod. It also machines well for custom parts, fixtures, and pads on standard woodworking and metalworking equipment. Use sharp tools, clear chips often, and control heat to keep edges clean and parts accurate.
