For making bookbinding clips, you would need\u00a0<\/span>flexible PVC (PVC-P) granules<\/span><\/strong>\u00a0specifically engineered to be tough, durable, and to hold their shape while being gentle on paper. The clips need to be strong enough to bind stacks of paper but also flexible enough for easy use.<\/span><\/p>\n

Formulation Focus: The Right Kind of Flexibility<\/span><\/h3>\n

The core challenge is achieving\u00a0<\/span>long-term elasticity<\/span><\/strong>. Low-cost plasticizers can migrate to the surface over time, causing the clip to become sticky and then brittle, losing its clamping strength<\/span>\u2013<\/span>1<\/span><\/span><\/a>\u2013<\/span>3<\/span><\/span><\/a>.
