Description
Reinforced Weather & Oil Resistant Rubber for Stable Gasket & Sealing Applications
Neoprene 65 Cotton Insertion Rubber Sheet is a premium-grade chloroprene (CR) rubber, reinforced with cotton fabric layers to improve dimensional stability, strength, and durability.
With a hardness of 65 Duro, this material offers a balance of firmness and flexibility, while the cotton reinforcement reduces stretching and deformation, making it ideal for gasket, sealing,
and isolation applications under load.
