Frequently Asked Questions

What is the difference between rigid and flexible PVC?

Rigid PVC contains no plasticizers, offering high strength and stiffness for construction and piping applications. Flexible PVC includes plasticizers providing softness and flexibility for medical tubing, cables, and consumer products. We process both formulations based on your requirements.

Is PVC suitable for medical applications?

Yes, medical-grade PVC formulations are widely used in healthcare for blood bags, IV tubes, and disposable devices. We use FDA-approved materials and maintain clean room standards for medical-grade PVC molding with full material certification.

Does PVC require drying before processing?

PVC has low moisture absorption and typically does not require pre-drying. However, if material has been stored in humid conditions, light drying at 70-80°C for 1-2 hours may be beneficial to ensure optimal processing and part quality.

What tolerances can be achieved with PVC?

Typical tolerances for PVC injection molding range from ±0.05mm to ±0.15mm depending on part size and geometry. PVC has low shrinkage (0.2-0.6%) allowing for good dimensional accuracy with proper mold design and process control.

Is PVC environmentally friendly?

PVC is recyclable and has a long service life reducing replacement needs. Modern PVC formulations minimize environmental impact. We follow responsible manufacturing practices and can provide recycled PVC options for sustainable applications.

Can PVC parts be colored or transparent?

Yes, PVC accepts pigments well and can be produced in virtually any color. Clear transparent PVC is also available for applications requiring visibility. We offer custom color matching services to meet your specific aesthetic requirements.
