PP-C Sheet, Gray, Custom, Chemical Equipment . Accurate Solutions . No Surface Film Fabrication . Film Adhesive Fabrication Friction of Surface Film Adhesives.
Industrial panels usually have protective covers that leave a sticky residue when removed. It catches airborne dust, clogs CNC routing tools, and destroys plastic welding seams.
The custom grey PP Sheet overcomes this processing barrier. It is produced without a surface film, eliminating cleaning steps, so shops can move panels directly from inventory to the CNC router or welding bench.

Zero Glue Residue Processing
Normal panels use temporary films that degrade with heat or long storage. The Non-film grey Polypropylene Plastic Sheets is shipped bare and offers a smooth matte surface.
Clean Surface : Panels can be wiped down with no chemical solvents for processing.
CNC Tool Preservation : How to Avoid Sticky Build-Up on CNC Bits to Help Maintain Cutting Edge Sharpness
Direct Joining : Welding rods of plastic are joined without contamination by dissolved adhesive residues.
Copolymer Chemistry for Mechanical Equilibrium: This structural design offers improved impact resistance relative to conventional homopolymer versions, especially at lower operating temperatures.
When making custom tanks, the balanced flexibility prevents cracking around punched holes, rivet points or tight bend radii.
Chemical Resistance Properties
Structural materials for industrial process environments must tolerate continuous exposure to corrosive liquids
Compatibility with Media
Acids: Resists sulphuric acid up to 70% and solutions of hydrochloric acid.
Alkalis: Not affected by sodium hydroxide and potassium hydroxide wash baths.
Solvents: Maintains structural integrity in the presence of inorganic salt solutions and alcohol.
The polymer structure is non-polar and does not absorb fluid and in fluid collection systems there is no swelling or thinning of the walls.
Primary Use Cases
Chemical Pickling Tanks : High acid resistance & good welded joints
Scrubbing Towers : Low density reduces the load on the structural frame [ Electroplating Baths ] Heavy Metal Parts Impact Strength Handles
Chemical Storage & Pickling Baths
Fabricators employ these panels in the fabrication of acid pickling tanks, plating tubs, and neutralisation vessels. Smooth matte surface for easier fillet welds, with standard PP welding rod.
Ventilation and Ducting Systems
Lightweight materials with high tensile strength are required for fume extraction hoods and wet scrubbing towers. This material reduces total system weight and continuously handles corrosive vapour streams.
Machining Parts for Industry
These Polypropylene Plastic Sheets are cut in machining shops into custom baffles, valve bodies, flange gaskets and filter press plates. The copolymer composition provides clean edges without burr build-up during high-speed milling.
Custom Sizing & Wholesale Specifications

FAQs
Q: Why choose a custom grey PP-C sheet without protective film?
A: Film adhesives leave sticky glue on plastic panels. This residue takes time to remove and damages CNC tools Our non-film sheets are cut and ready for welding immediately.
Q: Is this sheet suitable for plastic welding?
A: Yes. There is no film residue that leaves the surface clean. Standard PP welding rods fuse cleanly with no adhesive contamination to weaken the joint.
