Flexible PVC Injection Molding: Properties, Applications and Design Guide
Flexible PVC compounds use plasticizer packages to deliver rubber-like feel while remaining thermoplastic for injection molding.

When to specify Flexible PVC
How procurement and design teams use Flexible PVC on injection molded programs.
Flexible PVC compounds use plasticizer packages to deliver rubber-like feel while remaining thermoplastic for injection molding. Typical parts include tubing connectors, soft-touch grips, and gaskets where TPE might also compete on feel and cost. Grade selection controls hardness (Shore A), extractables, and regulatory fit, so name the target durometer range on the RFQ. At NetProto, programs run from first-article validation through production on one hardened steel tool with no minimum order quantity. Upload CAD on the instant quote platform for DFM feedback before tooling release. For a higher-heat PVC, see the CPVC page. For a clear rigid alternative, see the SAN page.

Common grades
Common Flexible PVC grades by use case
Pick one of these on the instant quote, or name any other commercial grade in the RFQ notes. Plasticizer type varies by grade. Confirm phthalate-free or other regulatory limits on the supplier TDS.
| Use case | Example grade | Typical parts |
|---|---|---|
| General flexible | Geon Vinyl Flexible C8000 | Flexible seals, grips, and general soft moldings |
| General flexible | Geon Vinyl Flexible B6000 | Soft touch parts and flexible industrial components |
| Wire and cable jacket | Geon Vinyl Wire and Cable W3400L | Cord jacketing and cable applications |
| Flexible molding | Geon Vinyl Flexible WMJF260 | Custom flexible profiles and moldings |
Applications
Where this resin shows up on BOMs
Typical molded parts and what to specify on the purchase order.
| Application | Why this resin | Specify on the PO |
|---|---|---|
| Medical tubing connectors (non-implant) | Soft grip and seal surfaces | Grade + supplier compliance documents requested from resin vendor |
| Tool grips and handles | Lower cost than some TPEs at high hardness | Shore A target or sample to match |
| Gaskets and boots | Compression set depends on plasticizer stability | Fluid contact and temperature notes |
| Wire harness wrap | Flexibility and cold bend | Listing target and temperature class, verified on supplier documents |
Routing
Rigid or flexible PVC
Pick the PVC family first. Each has its own page. Check the Shore A range and plasticizer limits before switching families.
| Family | Typical parts | Watch for |
|---|---|---|
| Flexible PVC | Grips, seals, strain reliefs, tubing parts | Plasticizer choice and compliance documents |
| Rigid PVC | Pipe fittings, enclosures, electrical boxes | Heat limits and corrosive gases during molding |
| TPE instead of PVC | Soft parts without plasticizers | Bond to substrate and hardness range |

Flexible PVC injection molding FAQ
Flexible PVC vs TPE?
TPEs often simplify recycling and reduce odor concerns. Flexible PVC is the usual route when the part needs a specified plasticizer package and a wide hardness span. Choose TPE when the program needs a plasticizer-free compound. Confirm both on the supplier TDS.
Does flexible PVC need drying?
Some compounds are sensitive to moisture; follow the supplier TDS drying guidance.
Can flexible PVC overmold onto rigid PVC?
Often yes with compatible grades; specify both compounds on the BOM.
What is the minimum order quantity for molded parts at NetProto?
NetProto has no minimum order quantity on molded parts from your production tool. Upload CAD on the instant quote platform to scope tooling and part pricing for your volume.
How do I quote this resin without a final grade selected?
List the resin family on the RFQ, attach environment and compliance notes, and upload CAD. At NetProto, engineers use DFM review to narrow grades before tooling release.
