Frequently Asked Questions
Can black PP sheets be used for chemical tanks?
Yes! Black polypropylene offers excellent resistance to most acids, bases, and solvents - perfect for chemical tank liners. Our welding services can create leak-proof tanks and containers.
Is this FDA-approved for food contact?
Yes, our food-grade PP sheets meet FDA 21 CFR 177.1520 requirements. Safe for cutting boards, food trays, and kitchen equipment. We provide material certification with food-grade orders.
Can you provide CNC machining services?
Absolutely! We offer polypropylene CNC machining with 3/4/5-axis capabilities. Tolerances down to ±0.03mm. Upload your CAD file for a free quote within 1 business day.
How do I join PP sheets together?
PP cannot be glued with standard adhesives. Best methods: (1) Hot air welding - strongest for permanent joints (our welding service), (2) Ultrasonic welding for thin sheets, (3) Mechanical fasteners for assemblies.
What thickness should I choose for my application?
4-6mm: Lightweight panels, dividers, food trays
8-10mm: Machine guards, structural parts, cutting boards
12-20mm: Heavy-duty applications, thick wear plates, tank walls

CUSTOM FABRICATION
Can't Find the Right Size or Specification?
Send your drawing or dimensions, material grade if known, quantity and intended use. We review feasibility and confirm the specification for each quoted project.
Project Requirements
Identify the critical dimensions, tolerances, surface finish and inspection requirements. Any required food-contact, ESD, flame-retardant or other compliance documents should be specified so availability can be checked. Material names alone do not establish these properties.
Custom Order Process
Submit the requirements for review. The quotation will identify the agreed specification, quantity, production lead time and inspection requirements. Shipping method, shipping charges and tax responsibilities are confirmed separately from production timing. Approve the final quotation and specification before ordering.
Send Your Drawing or Requirements
Use the enquiry form to send your project details and a file link, or email drawings to custominsul@protonmail.com. Include the product and specification. If the material grade or tolerance is uncertain, describe the intended use for review.
