PVC, Plastisol, Vinyl, Silicone, Urethane, Polyurethane, Latex, TPE, Thermo plastic elastomers - what's the difference?
A good question... each material has its benefits. Do you need thin walled medical tubing or medical balloons, good tear resistance, solvent resistance, elongation, maximum extension, or just cheap as possible!
Whatever your needs, dip molding provides intricate plastic or rubber shapes with minimal tooling costs with unbeatable turnaround time compared to expensive injection molding.
Typical values. Users should confirm results by their own tests.
