PVC Hoses: Material Selection Guide

PVC hoses are widely used in industrial, agricultural, automotive, construction and household applications. The performance of the hose is shaped according to material components such as plasticizer type, PVC resin quality, stabilizer structure and reinforcement type.

1. Plasticizer Selection

• DOTP

General purpose, high flexibility

• DINP

High mechanical strength

• DOA

Excellent flexibility at low temperature

• TOTM

Resistance to hot environments

2. Stabilizer Selection

• Ca-Zn stabilizers

Ideal for lead-free, reach compliant hoses.

3. Reinforcement Structure

• Straight hose

• Spiral reinforced hose

• Braided hose

• Double layer hose

Each structure offers different pressure and strength.

4. Performance Requirements

• Flexibility

• Compressive strength

• UV resistance

• Oil and chemical resistance

Conclusion

The hose quality depends on the correct PVC receiver, the right plasticizer and the right stabilizer. The more difficult the implementation, formulation becomes so critical.
