Key Considerations in PVC Hose Production

As a professional PVC compound supplier, we understand that producing high-quality hoses requires not only advanced equipment but also the right formulation and strict process control. Below are the key considerations in PVC hose production:

• Material Selection

  • Choose the right PVC compound based on hose applications (garden hoses, industrial hoses, medical hoses, etc.).

  • Ensure additives such as plasticizers, stabilizers, and colorants are well-balanced for flexibility, durability, and safety.

• Processing Temperature

  • Maintain precise temperature control during extrusion to avoid issues such as scorching, discoloration, or reduced mechanical strength.

  • Gradual heating and stable cooling are essential for dimensional stability.

• Pressure and Strength Requirements

  • Adjust formulation and reinforcement (braided or spiral layers) according to working pressure demands.

  • Regularly test tensile strength, burst pressure, and bending resistance.

• Surface Quality

  • Monitor extrusion speed and cooling to ensure smooth, bubble-free, and glossy surfaces.

  • Prevent contamination from dust or impurities during production.

• Flexibility and Weather Resistance

  • For outdoor hoses, UV resistance and anti-aging agents must be included to extend service life.

  • For low-temperature applications, special cold-resistant modifiers should be used.

• Compliance and Safety

  • Ensure products meet international standards such as RoHS, REACH, FDA, or other local regulations depending on application.

  • Use non-toxic plasticizers for hoses intended for potable water or food contact.

• Continuous Quality Control

  • Implement strict inspection procedures, including dimensional checks, impact resistance, and aging tests.

  • Keep production records to ensure traceability and consistency.
