Pre-expanded silicone rubber sleeve shrinks at ambient temperature without heat.

Anti-slip texture with integrated core member (e.g., cork or EPDM) for ergonomic grip.

High elasticity (-55℃~150℃ range)，resistant to UV，saltwater，and abrasion.

Fish-scale texture or cross-line pattern for enhanced friction in wet conditions.

Ideal for saltwater environments due to corrosion-resistant materials.

Lightweight design (20%-30% lighter than EVA) reduces fatigue during casting.
