Natural cast tubular bars and plastic sheet are produced using a high-purity caprolactam monomer via an anionic polymerization casting process. Retaining the material's natural color without the addition of color masterbatches or modifying additives, the product boasts high purity and mechanical properties that closely match those of the virgin Nylon 6 base resin, making it an ideal choice for applications in food contact, medical equipment, and precision instruments.

Product Features
Pure Raw Materials
Contains no added pigments or fillers; features a simple composition, making it ideal for industries with stringent material requirements.
Consistent Quality
Molecular weight of 70,000–100,000; consistent mechanical properties across batches, free from impurity interference.
Clean Processing
Free from low-molecular-weight additives; no frosting or leaching during engraving and thermoforming, ensuring no contamination of molds or processing media.
Safe and Compliant
Meets FDA food-grade standards for direct food contact; suitable for food processing and packaging equipment.
Low Stress, No Warping
Cast using a process that minimizes internal stress, ensuring dimensional stability after machining and resistance to bending or deformation.
Wide Temperature Tolerance
Withstands long-term temperatures from -40°C to 110°C and short-term exposure exceeding 150°C.
Quality Assurance
Raw Material Control
Uses high-purity caprolactam monomer; no recycled materials used; purity and impurity levels tested for every incoming batch.
Process Purity
Strict contamination prevention during casting; separate production lines for natural-color and colored tubing to avoid cross-contamination.
Testing & Verification
Random sampling of each batch for tensile strength, impact toughness, and color/appearance to ensure batch-to-batch consistency.
Documentation
Material inspection reports and dimensional inspection reports provided with the shipment.
FAQ
Q: Does long-term storage affect the performance of Natural Cast Tubular Bar Plastic Sheet?
A: Performance remains stable over the long term when stored in a cool, dry place away from direct light. As no UV stabilizers are added, direct exposure to sunlight may cause slight yellowing, but this does not affect the material's strength.
Q: How should I choose between the three forms-tubes, rods, and sheets-of Natural Cast Tubular Bar Plastic Sheet?
A: Tubes are suitable for pipe sleeves; rods are ideal for shafts and small precision parts; and sheets are used for structural spacers and blanks for large components. All three forms share the same material composition; selecting the form that best matches the final part shape minimizes machining allowances and reduces costs.
Q: Can you provide a material composition statement or an SDS/MSDS?
A: Yes. A material declaration and Safety Data Sheet (SDS/MSDS) are provided with the shipment to facilitate compliance audits.
