Plastisol
Understanding Plastisol
Plastisol is the most widely used material in modern soft plastic lure manufacturing.
From worms and grubs to swimbaits, creatures, tubes, and countless other designs, plastisol has become the foundation of the soft bait industry because it combines flexibility, durability, customization, and fish-catching action.
Although many soft plastic lures appear similar, small differences in plastisol formulation can dramatically affect how a lure moves, sinks, stretches, and performs in the water.
Understanding plastisol helps explain why different soft baits behave differently and why certain designs excel in specific fishing situations.
Why Plastisol Matters
The physical properties of plastisol influence:
- lure action
- flexibility
- sink rate
- buoyancy
- durability
- stretch resistance
- color retention
- fish response
Changes in softness, density, additives, and formulation can significantly alter lure performance.
Understanding these relationships is one of the foundations of soft plastic lure design.
